                              EMPLOYMENT AGREEMENT

            THIS AGREEMENT is made and entered into as of the 1st day of March,
2000, by and between LYDALL, INC., a Delaware corporation (the "Company"), and
Mona G. Estey (the "Executive").

                               W I T N E S S E T H

            WHEREAS, the Company and the Executive (the "Parties") have agreed
to enter into this agreement (the "Agreement) relating to the employment of the
Executive by the Company and/or one of its subsidiaries;

            NOW, THEREFORE, in consideration of the premises and mutual
covenants contained herein and for other good and valuable consideration, the
Parties, intending to be legally bound, agree as follows:

            1. Term of Employment; Termination of Prior Agreement.

            (a) The Company and/or one of its subsidiaries agrees to continue to
employ the Executive, and the Executive agrees to remain in the employment of
the Company and/or one of its subsidiaries, in accordance with the terms and
provisions of this Agreement.

            (b) The Employment Period under this Agreement shall be the period
commencing as of the date of this Agreement and, ending on the date of
termination of the Executive's employment pursuant to Section 5, 6 or 7 below,
whichever is applicable.

            (c) Immediately upon the commencement of the Executive's employment
pursuant to the terms of this Agreement, that certain Agreements by and between
the Executive and the Company dated as of February 1, 2000 and March 10, 1995
and shall terminate and shall be of no further force or effect.

            2. Duties. It is the intention of the Parties that during the term
of the Executive's employment under this Agreement, the Executive will serve as
Director, Human Resources of the Company or in such other senior management
position as the Company shall determine. During the Employment Period, the
Executive will devote her full business time and attention and best efforts to
the affairs of the Company and its subsidiaries

                                      -2-

and her duties as Director, Human Resources. The Executive will have such duties
as are appropriate to her position as Director, Human Resources, and will have
such authority as required to enable the Executive to perform these duties.
Consistent with the foregoing, the Executive shall comply with all reasonable
instructions of the Board of Directors of the Company (the "Board").

            3. Compensation and Benefits.

            3.1 Salary. During the Employment Period, the Company will pay the
Executive a base salary at an initial annual rate of One Hundred Fifteen
Thousand Dollars ($115,000). The Company may, in its sole and absolute
discretion, increase the Executive's base salary in light of the Executive's
performance, inflation, changes in the cost of living and other factors deemed
relevant by the Company. The Executive's base salary may not be decreased during
the term of this Agreement. The Chief Executive Officer of the Company shall
meet with the Executive annually to review the Executive's performance,
objectives and compensation, including salary, bonus and stock options, and the
Chief Executive Officer shall then meet with the Compensation and Stock Option
Committee of the Board (the "Compensation Committee") to discuss the same. If
the Compensation Committee determines that any adjustments thereto are
appropriate, such committee shall make a recommendation to the full Board and
the Board shall make such adjustments, if any, as the Board deems appropriate
and consistent with this Agreement. The Executive's base salary will be paid in
accordance with the standard practices for other corporate executives of the
Company.

            3.2 Bonuses. During the Employment Period, the Executive will be
eligible to receive annually or otherwise such bonus awards, if any, as shall be
determined by the Board in its sole and absolute discretion after receiving the
recommendation of the Compensation Committee.

            3.3 Benefit Programs. During the Employment Period, the Executive
will be entitled to participate on substantially the same terms as other senior
executives of the Company in all employee benefit plans and programs of the
Company (subject to any restrictions or eligibility requirements under such
plans and programs) from time to time in effect for the benefit of senior
executives of the Company, including, but not limited to, pension and other
retirement plans, profit sharing plans, stock incentive and annual incentive
bonus plans, group life insurance, hospitalization and surgical and major
medical cov-

                                      -3-

erages (excluding the Lydall, Inc. Executive Medical Plan), short-term and
long-term disability, and such other benefits as are or may be made available
from time to time to senior executives of the Company.

            3.4 Vacations and Holidays. During the Employment Period, the
Executive will be entitled to vacation leave of five (5) weeks per year at full
pay or such greater vacation benefits as may be provided for by the Company's
vacation policies applicable to senior executives. The Executive will be
entitled to such holidays as are established by the Company for all employees.

            4. Business Expenses. The Executive will be entitled to prompt
reimbursement for all reasonable, documented and necessary expenses incurred by
the Executive in performing her services hereunder, provided the Executive
properly accounts therefor in accordance with the policies and procedures
established by the Company.

            5. Termination of Employment by the Company.

            5.1 Involuntary Termination by the Company Other Than For Permanent
and Total Disability or Cause. The Company may terminate the Executive's
employment at any time other than (i) by reason of the Executive's Permanent and
Total Disability (as defined in Section 5.2) or (ii) for Cause (as defined in
Section 5.3), by giving the Executive a written notice of ter -mination at least
30 days before the date of termination (or such lesser notice period as the
Executive may agree to). In the event of such a termination of employment
pursuant to this Section 5.1, the Executive shall be entitled to receive (i) the
benefits described in Section 8 if such termination of employment does not occur
within 12 months following a "Change of Control" (as defined in Section 10), or
(ii) the benefits described in Section 9 if such termination of employment
occurs within 12 months following a "Change of Control" (as defined in Section
10).

            5.2 Termination Due to Permanent and Total Disability. If the
Executive incurs a Permanent and Total Disability, as defined below, the Company
may terminate the Executive's employment by giving the Executive written notice
of termination at least 30 days before the date of such termination (or such
lesser notice period as the Executive may agree to). In the event of such
termination of the Executive's employment because of Permanent and Total
Disability, the Executive shall be entitled to receive (i) her base salary
pursuant to Section 3.1

<PAGE>
                                      -4-

through the date which is twelve months following the date of such termination
of employment, reduced by any amounts paid to the Executive under any disability
program maintained by the Company, such base salary to be paid at the normal
time for the payment of such base salary, (ii) a bonus for the year of
termination of employment and for the next succeeding year (to be paid at the
normal time for payment of such bonuses) in an amount equal to the average of
the three highest annual bonuses earned by the Executive under the Company's
annual incentive bonus plan for any of the five calendar years preceding the
calendar year of her termination of employment (or, if the Executive was not
eligible for a bonus for at least three calendar years in such five-year period,
then the average of such bonuses for all of the calendar years in such five-year
period for which the Executive was eligible), with any deferred bonuses counting
for the year earned rather than the year paid; (iii) any other compensation and
benefits to the extent actually earned by the Executive under any other benefit
plan or program of the Company as of the date of such termination of employment,
such compensation and benefits to be paid at the normal time for payment of such
compensation and benefits, and (iv) any reimbursement amounts owing under
Section 4. In addition, if the Executive elects to continue coverage under the
Company's health plan pursuant to COBRA, the Company for a period of twelve
months following termination of the Executive's employment by reason of
Permanent and Total Disability will pay the same percentage of the Executive's
premium for COBRA coverage for the Executive and, if applicable, her spouse and
dependent children, as the Company paid at the applicable time for coverage
under such plan for actively employed senior executives generally. For the
period of twelve months following the termination of the Executive's employment
by reason of Permanent and Total Disability, the Company will continue to
provide the life insurance benefits that the Company would have provided to the
Executive if the Executive had continued in employment with the Company for such
period, but only if the Executive timely pays the portion of the premium for
such coverage that senior executives of the Company generally are required to
pay for such coverage, if any. For purposes of this Agreement, the Executive
shall be considered to have incurred a Permanent and Total Disability if and
only if the Executive has incurred a disability entitling the Executive to
disability benefits under the Company's long-term disability plan.

            5.3 Termination for Cause. The Company may terminate the Executive's
employment immediately for Cause for any of the following reasons: (i) an act or
acts of dishonesty or fraud on the part of the Executive resulting or intended
to re-

<PAGE>
                                      -5-

sult directly or indirectly in substantial gain or personal enrichment to which
the Executive was not legally entitled at the expense of the Company or any of
its subsidiaries; (ii) a willful material breach by the Executive of her duties
or responsibilities under this Agreement resulting in demonstrably material
injury to the Company or any of its subsidiaries; (iii) the Executive's
conviction of a felony or any crime involving moral turpitude, (iv) habitual
neglect or insubordination (defined as refusal to execute or carry out
directions from the Board or its duly appointed designees) where the Executive
has been given written notice of the acts or omissions constituting such neglect
or insubordination and the Executive has failed to cure such conduct, where
susceptible to cure, within thirty days following such notice, or (v) a material
breach by the Executive of any of his obligations under the Lydall Employee
Agreement executed by the Executive and attached hereto as Exhibit A. The
Company shall exercise its right to terminate the Executive's employment for
Cause by giving the Executive written notice of termination specifying in
reasonable detail the circumstances constituting such Cause. In the event of
such termination of the Executive's employment for Cause, the Executive shall be
entitled to receive only (i) her base salary pursuant to Section 3.1 earned
through the date of such termination of employment plus her base salary for the
period of any vacation time earned but not taken for the year of termination of
employment, such base salary to be paid at the normal time for payment of such
base salary, (ii) any other compensation and benefits to the extent actually
earned by the Executive under any other benefit plan or program of the Company
as of the date of such termination of employment, such compensation and benefits
to be paid and at the normal time for payment of such compensation and benefits
and (iii) any reimbursement amounts owing under Section 4.

            6. Termination of Employment by the Executive.

            (a) Good Reason. The Executive may terminate her employment for Good
Reason by giving the Company a written notice of termination at least 30 days
before the date of such termination (or such lesser notice period as the Company
may agree to) specifying in reasonable detail the circumstances constituting
such Good Reason. In the event of the Executive's termination of her employment
for Good Reason, the Executive shall be entitled to receive (i) the benefits
described in Section 8 if such termination of employment does not occur within
12 months following a "Change of Control" (as defined in Section 10), or (ii)
the benefits described in Section 9 if such termination of employment occurs
within 12 months following a

<PAGE>
                                      -6-

"Change of Control" (as defined in Section 10). For purposes of this Agreement,
Good Reason shall mean (i) a significant reduction in the scope of the
Executive's authority, functions, duties or responsibilities from that which is
contemplated by this Agreement, (ii) any reduction in the Executive's base
salary, (iii) a significant reduction in the employee benefits provided to the
Executive (excluding the Lydall, Inc. Executive Medical Plan) other than in
connection with an across-the-board reduction similarly affecting substantially
all senior executives of the Company, or (iv) any material breach by the Company
of any provision of this Agreement without the Executive having committed any
material breach of the Executive's obligations hereunder or under the Lydall
Employee Agreement which breach is not cured within thirty days following
written notice thereof to the Company of such breach. In addition, in the case
of a termination of employment within 12 months following a "Change of Control"
(as defined in Section 10), Good Reason shall also include the relocation of the
Executive's office location to a location more than 50 miles away from the
Executive's then current principal place of employment. If an event constituting
a ground for termination of employment for Good Reason occurs, and the Executive
fails to give notice of termination within 90 days after the occurrence of such
event, the Executive shall be deemed to have waived her right to terminate
employment for Good Reason in connection with such event (but not for any other
event for which the 90-day period has not expired).

            (b) Other. The Executive may terminate her employment at any time
and for any reason, other than pursuant to subsection (a) above, by giving the
Company a written notice of termination to that effect at least 30 days before
the date of termination (or such lesser notice period as the Company may agree
to); provided, however, that the Company following receipt of such notice from
the Executive may elect to have the Executive's employment terminate immediately
following its receipt of such notice. In the event of the Executive's
termination of her employment pursuant to this subsection (b), the Executive
shall be entitled to receive only (i) her base salary pursuant to Section 3.1
earned through the date of such termination of employment plus her base salary
for the period of vacation time earned but not taken for the year of termination
of employment, such base salary to be paid at the normal time for payment of
such base salary, (ii) any other compensation and benefits to the extent
actually earned by the Executive under any other benefit plan or program of the
Company as of the date of such termination of employment, such compensation and
benefits to be paid at the normal time for payment of such compen-

                                      -7-

sation and benefits, and (iii) any reimbursement amounts owing under Section 4.

            7. Termination of Employment By Death. In the event of the death of
the Executive during the course of her employment hereunder, the Executive's
estate (or other person or entity having such entitlement pursuant to the terms
of the applicable plan or program) shall be entitled to receive (i) the
Executive's base salary pursuant to Section 3.1 earned through the date of the
Executive's death plus the Executive's base salary for the period of vacation
time earned but not taken for the year of the Executive's death, such base
salary to be paid at the normal time for payment of such base salary, (ii) a
bonus for the year of the Executive's death (to be paid within 90 days after the
Executive's death) in an amount equal to a pro rata portion of the average of
the three highest annual bonuses earned by the Executive under the Company's
annual incentive bonus plan for any of the five calendar years preceding the
calendar year of the Executive's death (or, if the Executive was not eligible
for a bonus for at least three calendar years in such five-year period, then the
average of such bonuses for all of the calendar years in such five-year period
for which the Executive was eligible), with any deferred bonuses counting for
the year earned rather than the year paid and with the pro rata portion being
determined by dividing the number of days of the Executive's employment during
such calendar year up to her death by 365 (366 if a leap year), (iii) any other
compensation and benefits to the extent actually earned by the Executive under
any other benefit plan or program of the Company as of the date of such
termination of employment, such compensation and benefits to be paid at the
normal time for payment of such compensation and benefits, and (iv) any
reimbursement amounts owing under Section 4. In addition, in the event of such
death, the Executive's beneficiaries shall receive any death benefits owed to
them under the Company's employee benefit plans. If the Executive's spouse
and/or dependent children elect to continue coverage under the Company's health
plan following the Executive's death pursuant to COBRA, the Company for a period
of 12 months following the Executive's death will pay the same percentage of the
premium for COBRA coverage for the Executive's spouse and/or dependent children,
as applicable, as the Company would have paid in respect of the Executive's
coverage under such plan if the Executive had continued in employment with the
Company for such period.

            8. Benefits Upon Termination Without Cause or For Good Reason (No
Change of Control). If (a) the Executive's em-

<PAGE>
                                      -8-

ployment hereunder shall terminate (i) because of termination by the Company
other than for Cause or Permanent and Total Disability pursuant to Section 5.1,
or (ii) because of termination by the Employee for Good Reason pursuant to
Section 6(a), and (b) such termination of employment does not occur within 12
months following a "Change of Control" of the Company (as defined in Section
10), the Executive shall be entitled to the following:

            (a) The Company shall pay to the Executive her base salary pursuant
      to Section 3.1 earned through the date of such termination of employment
      and any other compensation and benefits to the extent actually earned by
      the Executive under any benefit plan or program of the Company as of the
      date of such termination of employment, such base salary, compensation and
      benefits to be paid at the normal time for payment of such base salary,
      compensation and benefits.

            (b) The Company shall pay the Executive any reimbursement amounts
      owing under Section 4.

            (c) The Company shall pay to the Executive in equal installments
      spread over the period of 12 months beginning on the date of the
      Executive's termination of employment an amount equal in the aggregate to
      the sum of (i) the Executive's annual rate of base salary immediately
      preceding her termination of employment, and (ii) the average of her
      annual bonuses earned under the Company's annual incentive bonus plan for
      the three calendar years preceding her termination of employment (or, if
      the Executive was not eligible for a bonus in each of those three calendar
      years, then the average of such bonuses for all of the calendar years in
      such three-year period for which she was eligible), with any deferred
      bonuses counting for the year earned rather than the year paid. Such
      installments shall be paid at the times that salary payments are normally
      made by the Company.

            (d) If the Executive elects to continue coverage under the Company's
      health plan pursuant to COBRA, then for the period beginning on the date
      of the Executive's termination of employment and ending on the earlier of
      (i) the date which is 12 months after the date of such termination of
      employment or (ii) the date on which the Executive commences substantially
      full-time employment as an employee of an employer that offers health
      benefits, the Company will pay the same percentage of the Executive's
      premium

<PAGE>
                                      -9-

      for COBRA coverage for the Executive and, if applicable, her spouse and
      dependent children, as the Company paid at the applicable time for
      coverage under such plan for actively employed senior executives
      generally. In addition, for the period beginning on the date of the
      Executive's termination of employment and ending on the earlier of (i) the
      date which is 12 months after the date of such termination of employment
      or (ii) the date on which the Executive commences substantially full-time
      employment as an employee of an employer that offers life insurance
      benefits, the Company will continue to provide the life insurance benefits
      that the Company would have provided to the Executive if the Executive had
      continued in employment with the Company for such period, but only if the
      Executive timely pays the portion of the premium for such coverage that
      senior executives of the Company generally are required to pay for such
      coverage, if any. The Executive shall notify the Company promptly if she,
      while eligible for benefits under this subsection (d), commences
      substantially full-time employment as an employee of an employer that
      offers health and/or life insurance benefits.

            (e) The Company will provide the Executive with outplacement
      services selected by the Executive, at the Company's expense not to exceed
      $10,000.

            9. Benefits Upon Termination Without Cause or For Good Reason
(Change of Control). If (a) the Executive's employment hereunder shall terminate
(i) because of termination by the Company other than for Cause or Permanent and
Total Disability pursuant to Section 5.1, or (ii) because of termination by the
Employee for Good Reason pursuant to Section 6(a), and (b) such termination of
employment occurs within 12 months following a "Change of Control" of the
Company (as defined in Section 10), the Executive shall be entitled to the
following:

            (a) The Company shall pay to the Executive her base salary pursuant
      to Section 3.1 earned through the date of such termination of employment
      and any other compensation and benefits to the extent actually earned by
      the Executive under any benefit plan or program of the Company as of the
      date of such termination of employment, such base salary, compensation and
      benefits to be paid at the normal time for payment of such base salary,
      compensation and benefits.

            (b) The Company shall pay the Executive any reimbursement amounts
      owing under Section 4.

<PAGE>
                                      -10-

            (c) The Company shall pay to the Executive as a severance benefit an
      amount equal to two (2) times the sum of (i) her annual rate of base
      salary immediately preceding her termination of employment, and (ii) the
      average of her three highest annual bonuses earned under the Company's
      annual incentive bonus plan for any of the five calendar years preceding
      her termination of employment (or, if the Executive was not eligible for a
      bonus for at least three calendar years in such five-year period, then the
      average of such bonuses for all of the calendar years in such five-year
      period for which the Executive was eligible), with any deferred bonuses
      counting for the year earned rather than the year paid. Such severance
      benefit shall be paid in a lump sum within 30 days after the date of such
      termination of employment.

            (d) The Company shall pay to the Executive as a bonus for the year
      of termination of her employment an amount equal to a portion (determined
      as provided in the next sentence) of the Executive's maximum bonus
      opportunity under the Company's annual incentive bonus plan for the
      calendar year of termination of the Executive's employment or, if none,
      such portion of the bonus awarded to the Executive under the Company's
      annual incentive bonus plan for the calendar year immediately preceding
      the calendar year of the termination of her employment, with deferred
      bonuses counting for the year earned rather than the year paid. Such
      portion shall be determined by dividing the number of days of the
      Executive's employment during such calendar year up to her termination of
      employment by 365 (366 if a leap year). Such payment shall be made in a
      lump sum within 30 days after the date of such termination of employment,
      and the Executive shall have no right to any further bonuses under said
      plan.

            (e) During the period of 24 months beginning on the date of the
      Executive's termination of employment, the Executive (and, if applicable,
      the Executive's spouse and dependent children) shall remain covered by the
      medical, dental, life insurance, and, if reasonably commercially available
      through nationally reputable insurance carriers, long-term disability
      plans of the Company that covered the Executive immediately prior to her
      termination of employment as if the Executive had remained in employment
      for such period; provided, however, that the coverage under any such plan
      is conditioned on the timely payment by the Executive (or her spouse or
      dependent children) of the portion of the premium for such coverage that
      actively em-

<PAGE>
                                      -11-

      ployed senior executives with the Company generally are required to pay
      for such coverage. In the event that the Executive's participation in any
      such plan is barred, the Company shall arrange to provide the Executive
      (and, if applicable, her spouse and dependent children) with substantially
      similar benefits (but, in the case of long-term disability benefits, only
      if reasonably commercially available).

            (f) The Company shall supplement the benefits payable in respect of
      the Executive under the Company's Pension Plan and Supplemental Executive
      Retirement Plan (and any successor plans thereto) (collectively, the
      "Pension Plans") by paying the difference between (i) the benefits that
      the Executive would have been entitled to receive under the Pension Plans
      if she had been credited with two additional years of service (but no
      additional years of age) for purposes of the benefit accrual formula under
      the Pension Plans as of the date of termination of the Executive's
      employment and (ii) the benefits that the Executive is entitled to receive
      under the Pension Plans determined without regard to this subsection (f).
      Such benefits shall be payable in the same form and at the same time as
      the benefits under the respective Pension Plans.

            (g) Each stock option granted by the Company to the Executive and
      outstanding immediately prior to termination of her employment shall be
      fully vested and immediately exercisable and may be exercised by the
      Executive (or, following her death, by the person or entity to which such
      option passes) at any time prior to the expiration date of the applicable
      option (determined without regard to any earlier termination of the option
      that would otherwise occur by reason of termination of her employment).
      Each restricted stock award granted by the Company to the Executive and
      outstanding immediately prior to termination of the Executive's employment
      shall be fully vested upon such termination of employment.

            (h) The Company will provide the Executive with out-placement
      services selected by the Executive, at the Company's expense not to exceed
      $10,000.

            (i) The Company shall promptly pay all reasonable attorneys' fees
      and related expenses incurred by the Executive in seeking to obtain or
      enforce any right or benefit under this Agreement or to defend against any
      claim or

<PAGE>
                                      -12-

      assertion in connection with this Agreement, but only to the extent the
      Executive substantially prevails.

            10. Change of Control. For the purposes of this Agreement, a "Change
of Control" shall be deemed to have occurred if (a) any person or persons acting
together which would constitute a "group" for purposes of Section 13(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), (other than
the Company or any subsidiary of the Company) shall beneficially own (as defined
in Rule 13d-3 of the Exchange Act), directly or indirectly, at least 25% of the
total voting power of all classes of capital stock of the Company entitled to
vote generally in the election of the Board; (b) Current Directors (as herein
defined) shall cease for any reason to constitute at least a majority of the
members of the Board (for this purpose, a "Current Director" shall mean any
member of the Board as of the date hereof and any successor of a Current
Director whose election, or nomination for election by the Company's
shareholders, was approved by at least a majority of the Current Directors then
on the Board); (c) the shareholders of the Company approve (i) a plan of
complete liquidation of the Company or (ii) an agreement providing for the
merger or consolidation of the Company other than a merger or consolidation in
which (x) the holders of the common stock of the Company immediately prior to
the consolidation or merger have, directly or indirectly, at least a majority of
the common stock of the continuing or surviving corporation immediately after
such consolidation or merger or (y) the Board immediately prior to the merger or
consolidation would, immediately after the merger or consolidation, constitute a
majority of the board of directors of the continuing or surviving corporation;
or (d) the shareholders of the Company approve an agreement (or agreements)
providing for the sale or other disposition (in one transaction or a series of
transactions) of all or substantially all of the assets of the Company.

            11. Golden Parachute Excise Tax.

            (a) In the event that any payment or benefit received or to be
received by the Executive pursuant to this Agreement or any other plan, program
or arrangement of the Company or any of its affiliates would constitute an
"excess parachute payment" within the meaning of Section 280G of the Internal
Revenue Code of 1986, as amended (the "Code"), then the payments under this
Agreement shall be reduced (by the minimum possible amounts) until no amount
payable to the Executive under this Agreement constitutes an "excess parachute
payment" within the meaning of Section 280G of the Code; provided, how-

<PAGE>
                                      -13-

ever, that no such reduction shall be made if the net after-tax payment (after
taking into account Federal, state, local or other income and excise taxes) to
which the Executive would otherwise be entitled without such reduction would be
greater than the net after-tax payment (after taking into account Federal,
state, local or other income and excise taxes) to the Executive resulting from
the receipt of such payments with such reduction. If, as a result of subsequent
events or conditions (including a subsequent payment or absence of a subsequent
payment under this Agreement or other plan, program or arrangement of the
Company or any of its affiliates), it is determined that payments under this
Agreement have been reduced by more than the minimum amount required to prevent
any payments from constituting an "excess parachute payment", then an additional
payment shall be promptly made to the Executive in an amount equal to the
additional amount that can be paid without causing any payment to constitute an
excess parachute payment.

            (b) All determinations required to be made under this Section 11
shall be made by a nationally recognized independent accounting firm mutually
agreeable to the Company and the Executive (the "Accounting Firm") which shall
provide detailed supporting calculations to the Company and the Executive as
requested by the Company or the Executive. All fees and expenses of the
Accounting Firm shall be borne solely by the Company and shall be paid by the
Company upon demand of the Executive as incurred or billed by the Accounting
Firm. All determinations made by the Accounting Firm pursuant to this Section 11
shall be final and binding upon the Company and the Executive.

            (c) To the extent any payment or benefit is to be reduced pursuant
to this Section 11, the severance payment described in Section 8(c) or 9(c) will
first be reduced, then the bonus described in Section 9(d), and then the
supplemental pension benefits described in Section 9(f), in each case only to
the extent necessary.

            12. Entitlement to Other Benefits. Except as otherwise provided in
this Agreement, this Agreement shall not be construed as limiting in any way any
rights or benefits that the Executive or her spouse, dependents or beneficiaries
may have pursuant to any other plan or program of the Company.

            13. Indemnification. The parties agree to execute a separate
Indemnification Agreement in the form attached as Exhibit B.

                                      -14-

            14. General Provisions.

            14.1 No Duty to Seek Employment. The Executive shall not be under
any duty or obligation to seek or accept other employment following termination

except as expressly set forth herein.

            14.2 Deductions and Withholding. All amounts payable or which become

Executive's employment.

                                      -15-

            14.5 Proprietary Information and Inventions. The Lydall Employee
Agreement previously executed by the Executive and attached hereto as Exhibit A
is incorporated by reference in this Agreement, and the Executive agrees to
continue to be bound thereby.

            14.6 Covenant to Notify Management. The Executive agrees to abide by
the ethics policies of the Company as well as the Company's other rules,
regulations, policies and procedures. The Executive agrees to comply in full
with all governmental laws and regulations as well as ethics codes applicable.
In the event that the Executive is aware or suspects the Company, or any of its
officers or agents, of violating any such laws, ethics, codes, rules,
regulations, policies or procedures, the Executive agrees to bring all such
actual and suspected violations to the attention of the Company immediately so
that the matter may be properly investigated and appropriate action taken. The
Executive understands that the Executive is precluded from filing a complaint
with any governmental agency or court having jurisdiction over wrongful conduct
unless the Executive has first notified the Company of the facts and permits it
to investigate and correct the concerns.

            14.7 Amendments and Waivers. No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing signed by the Executive and the Company. No waiver by
either Party hereto at any time of any breach by the other Party hereto of, or
compliance with, any condition or provision of this Agreement to be performed by
such other Party shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time.

            14.8 Beneficial Interests. This Agreement shall inure to the benefit
of and be enforceable by a) the Company's successors and assigns and b) the
Executive's personal and legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If the Executive shall
die while any amounts are still payable to her hereunder, all such amounts,
unless otherwise provided herein, shall be paid in accordance with the terms of
this Agreement to the Executive's devisee, legatee, or other designee or, if
there be no such designee, to the Executive's estate.

            14.9 Successors. The Company will require any successors (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and

<PAGE>
                                      -16-

agree to perform this Agreement in the same manner and to the same extent that
the Company would be required to perform.

            14.10 Assignment. This Agreement and the rights, duties, and
obligations hereunder may not be assigned or delegated by any Party without the
prior written consent of the other Party and any attempted assignment or
delegation without such prior written consent shall be void and be of no effect.
Notwithstanding the foregoing provisions of this Section 14.10, the Company may
assign or delegate its rights, duties and obligations hereunder to any affiliate
or to any person or entity which succeeds to all or substantially all of the
business of the Company or one of its subsidiaries through merger, consolation,
reorganization, or other business combination or by acquisition of all or
substantially all of the assets of the Company or one of its subsidiaries.

            14.11 Choice of Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Connecticut.

            14.12 Statute of Limitations. The Executive and the Company hereby
agree that there shall be a one year statute of limitations for the filing of
any requests for arbitration or any lawsuit relating to this Agreement or the
terms or conditions of Executive's employment by the Company. If such a claim is
filed more than one year subsequent to the Executive's last day of employment it
shall be precluded by this provision, regardless of whether or not the claim has
accrued at that time.

            14.13 Right to Injunctive and Equitable Relief. The Executive's
obligations under Section 14.4 are of a special and unique character, which
gives them a peculiar value. The Company cannot be reasonably or adequately
compensated for damages in an action at law in the event the Executive breaches
such obligations. Therefore, the Executive expressly agrees that the Company
shall be entitled to injunctive and other equitable relief without bond or other
security in the event of such breach in addition to any other rights or remedies
which the Company may possess or be entitled to pursue. Furthermore, the
obligations of the Executive and the rights and remedies of the Company under
Section 14.4 and this Section 14.13 are cumulative and in addition to, and not
in lieu of, any obligations, rights, or remedies as created by applicable law.

            14.14 Severability or Partial Invalidity. The invalidity or
unenforceability of any provisions of this Agree-

<PAGE>
                                      -17-

ment shall not affect the validity or enforceability of any other provision of
this Agreement, which shall remain in full force and effect.

            14.15 Entire Agreement. This Agreement, along with the Lydall
Employee Agreement and the Indemnification Agreement by and between the
Executive and the Company, constitutes the entire agreement of the Parties and
supersedes all prior written or oral and all contemporaneous oral agreements,
understandings, and negotiations between the Parties with respect to the subject
matter hereof. This Agreement may not be changed orally and may only be modified
in writing signed by both Parties. This Agreement, along with the Lydall
Employee Agreement and the Indemnification Agreement, is intended by the Parties
as the final expression of their agreement with respect to such terms as are
included herein and therein and may not be contradicted by evidence of any prior
or contemporaneous agreement. The Parties further intend that this Agreement,
along with the Lydall Employee Agreement and the Indemnification Agreement,
constitutes the complete and exclusive statement of their terms and that no
extrinsic evidence may be introduced in any judicial proceeding involving such
agreements.

            14.16 Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed an original but all
of which together shall constitute one and the same instrument.

            IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed by its duly authorized officer and the Employee has hereunto set her
hand as of the day and year first above written.

                              EMPLOYMENT AGREEMENT

            THIS AGREEMENT is made and entered into as of the 1st day of March,
2000, by and between LYDALL, INC., a Delaware corporation (the "Company"), and
Mary A. Tremblay (the "Executive").

                               W I T N E S S E T H

            WHEREAS, the Company and the Executive (the "Parties") have agreed
to enter into this agreement (the "Agreement) relating to the employment of the
Executive by the Company and/or one of its subsidiaries;

            NOW, THEREFORE, in consideration of the premises and mutual
covenants contained herein and for other good and valuable consideration, the
Parties, intending to be legally bound, agree as follows:

            1. Term of Employment; Termination of Prior Agreement.

            (a) The Company and/or one of its subsidiaries agrees to continue to
employ the Executive, and the Executive agrees to remain in the employment of
the Company and/or one of its subsidiaries, in accordance with the terms and
provisions of this Agreement.

            (b) The Employment Period under this Agreement shall be the period
commencing as of the date of this Agreement and ending on the date of
termination of the Executive's employment pursuant to Section 5, 6 or 7 below,
whichever is applicable.

            (c) Immediately upon the commencement of the Executive's employment
pursuant to the terms of this Agreement, that certain Agreements by and between
the Executive and the Company dated as of February 1, 2000 and March 10, 1995
and shall terminate and shall be of no further force or effect.

            2. Duties. It is the intention of the Parties that during the term
of the Executive's employment under this Agreement, the Executive will serve as
General Counsel/Corporate Secretary of the Company or in such other senior
management position as the Company shall determine. During the Employment
Period, the Executive will devote her full business time and attention and best
efforts to the affairs of the Company and

<PAGE>
                                      -2-

its subsidiaries and her duties as General Counsel/Corporate Secretary. The
Executive will have such duties as are appropriate to her position as General
Counsel/Corporate Secretary, and will have such authority as required to enable
the Executive to perform these duties. Consistent with the foregoing, the
Executive shall comply with all reasonable instructions of the Board of
Directors of the Company (the "Board").

            3. Compensation and Benefits.

            3.1 Salary. During the Employment Period, the Company will pay the
Executive a base salary at an initial annual rate of One Hundred Twenty-Five
Thousand Dollars ($125,000). The Company may, in its sole and absolute
discretion, increase the Executive's base salary in light of the Executive's
performance, inflation, changes in the cost of living and other factors deemed
relevant by the Company. The Executive's base salary may not be decreased during
the term of this Agreement. The Chief Executive Officer of the Company shall
meet with the Executive annually to review the Executive's performance,
objectives and compensation, including salary, bonus and stock options, and the
Chief Executive Officer shall then meet with the Compensation and Stock Option
Committee of the Board (the "Compensation Committee") to discuss the same. If
the Compensation Committee determines that any adjustments thereto are
appropriate, such committee shall make a recommendation to the full Board and
the Board shall make such adjustments, if any, as the Board deems appropriate
and consistent with this Agreement. The Executive's base salary will be paid in
accordance with the standard practices for other corporate executives of the
Company.

            3.2 Bonuses. During the Employment Period, the Executive will be
eligible to receive annually or otherwise such bonus awards, if any, as shall be
determined by the Board in its sole and absolute discretion after receiving the
recommendation of the Compensation Committee.

            3.3 Benefit Programs. During the Employment Period, the Executive
will be entitled to participate on substantially the same terms as other senior
executives of the Company in all employee benefit plans and programs of the
Company (subject to any restrictions or eligibility requirements under such
plans and programs) from time to time in effect for the benefit of senior
executives of the Company, including, but not limited to, pension and other
retirement plans, profit sharing plans, stock incentive and annual incentive
bonus plans, group life insurance, hospitalization and surgical and major
medical cov-

<PAGE>
                                      -3-

erages (exluding the Lydall, Inc. Executive Medical Plan), short-term and
long-term disability, and such other benefits as are or may be made available
from time to time to senior executives of the Company.

            3.4 Vacations and Holidays. During the Employment Period, the
Executive will be entitled to vacation leave of three (3) weeks per year at full
pay or such greater vacation benefits as may be provided for by the Company's
vacation policies applicable to senior executives. The Executive will be
entitled to such holidays as are established by the Company for all employees.

            4. Business Expenses. The Executive will be entitled to prompt
reimbursement for all reasonable, documented and necessary expenses incurred by
the Executive in performing her services hereunder, provided the Executive
properly accounts therefor in accordance with the policies and procedures
established by the Company.

            5. Termination of Employment by the Company.

            5.1 Involuntary Termination by the Company Other Than For Permanent
and Total Disability or Cause. The Company may terminate the Executive's
employment at any time other than (i) by reason of the Executive's Permanent and
Total Disability (as defined in Section 5.2) or (ii) for Cause (as defined in
Section 5.3), by giving the Executive a written notice of termination at least
30 days before the date of termination (or such lesser notice period as the
Executive may agree to). In the event of such a termination of employment
pursuant to this Section 5.1, the Executive shall be entitled to receive (i) the
benefits described in Section 8 if such termination of employment does not occur
within 12 months following a "Change of Control" (as defined in Section 10), or
(ii) the benefits described in Section 9 if such termination of employment
occurs within 12 months following a "Change of Control" (as defined in Section
10).

            5.2 Termination Due to Permanent and Total Disability. If the
Executive incurs a Permanent and Total Disability, as defined below, the Company
may terminate the Executive's employment by giving the Executive written notice
of termination at least 30 days before the date of such termination (or such
lesser notice period as the Executive may agree to). In the event of such
termination of the Executive's employment because of Permanent and Total
Disability, the Executive shall be entitled to receive (i) her base salary
pursuant to Section 3.1

<PAGE>
                                      -4-

through the date which is twelve months following the date of such termination
of employment, reduced by any amounts paid to the Executive under any disability
program maintained by the Company, such base salary to be paid at the normal
time for the payment of such base salary, (ii) a bonus for the year of
termination of employment and for the next succeeding year (to be paid at the
normal time for payment of such bonuses) in an amount equal to the average of
the three highest annual bonuses earned by the Executive under the Company's
annual incentive bonus plan for any of the five calendar years preceding the
calendar year of her termination of employment (or, if the Executive was not
eligible for a bonus for at least three calendar years in such five-year period,
then the average of such bonuses for all of the calendar years in such five-year
period for which the Executive was eligible), with any deferred bonuses counting
for the year earned rather than the year paid; (iii) any other compensation and
benefits to the extent actually earned by the Executive under any other benefit
plan or program of the Company as of the date of such termination of employment,
such compensation and benefits to be paid at the normal time for payment of such
compensation and benefits, and (iv) any reimbursement amounts owing under
Section 4. In addition, if the Executive elects to continue coverage under the
Company's health plan pursuant to COBRA, the Company for a period of twelve
months following termination of the Executive's employment by reason of
Permanent and Total Disability will pay the same percentage of the Executive's
premium for COBRA coverage for the Executive and, if applicable, her spouse and
dependent children, as the Company paid at the applicable time for coverage
under such plan for actively employed senior executives generally. For the
period of twelve months following the termination of the Executive's employment
by reason of Permanent and Total Disability, the Company will continue to
provide the life insurance benefits that the Company would have provided to the
Executive if the Executive had continued in employment with the Company for such
period, but only if the Executive timely pays the portion of the premium for
such coverage that senior executives of the Company generally are required to
pay for such coverage, if any. For purposes of this Agreement, the Executive
shall be considered to have incurred a Permanent and Total Disability if and
only if the Executive has incurred a disability entitling the Executive to
disability benefits under the Company's long-term disability plan.

            5.3 Termination for Cause. The Company may terminate the Executive's
employment immediately for Cause for any of the following reasons: (i) an act or
acts of dishonesty or fraud on the part of the Executive resulting or intended
to re-

<PAGE>
                                      -5-

sult directly or indirectly in substantial gain or personal enrichment to which
the Executive was not legally entitled at the expense of the Company or any of
its subsidiaries; (ii) a willful material breach by the Executive of her duties
or responsibilities under this Agreement resulting in demonstrably material
injury to the Company or any of its subsidiaries; (iii) the Executive's
conviction of a felony or any crime involving moral turpitude, (iv) habitual
neglect or insubordination (defined as refusal to execute or carry out
directions from the Board or its duly appointed designees) where the Executive
has been given written notice of the acts or omissions constituting such neglect
or insubordination and the Executive has failed to cure such conduct, where
susceptible to cure, within thirty days following such notice, or (v) a material
breach by the Executive of any of his obligations under the Lydall Employee
Agreement executed by the Executive and attached hereto as Exhibit A. The
Company shall exercise its right to terminate the Executive's employment for
Cause by giving the Executive written notice of termination specifying in
reasonable detail the circumstances constituting such Cause. In the event of
such termination of the Executive's employment for Cause, the Executive shall be
entitled to receive only (i) her base salary pursuant to Section 3.1 earned
through the date of such termination of employment plus her base salary for the
period of any vacation time earned but not taken for the year of termination of
employment, such base salary to be paid at the normal time for payment of such
base salary, (ii) any other compensation and benefits to the extent actually
earned by the Executive under any other benefit plan or program of the Company
as of the date of such termination of employment, such compensation and benefits
to be paid and at the normal time for payment of such compensation and benefits
and (iii) any reimbursement amounts owing under Section 4.

            6. Termination of Employment by the Executive.

            (a) Good Reason. The Executive may terminate her employment for Good
Reason by giving the Company a written notice of termination at least 30 days
before the date of such termination (or such lesser notice period as the Company
may agree to) specifying in reasonable detail the circumstances constituting
such Good Reason. In the event of the Executive's termination of her employment
for Good Reason, the Executive shall be entitled to receive (i) the benefits
described in Section 8 if such termination of employment does not occur within
12 months following a "Change of Control" (as defined in Section 10), or (ii)
the benefits described in Section 9 if such termination of employment occurs
within 12 months following a

<PAGE>
                                      -6-

"Change of Control" (as defined in Section 10). For purposes of this Agreement,
Good Reason shall mean (i) a significant reduction in the scope of the
Executive's authority, functions, duties or responsibilities from that which is
contemplated by this Agreement, (ii) any reduction in the Executive's base
salary, (iii) a significant reduction in the employee benefits provided to the
Executive (excluding the Lydall, Inc. Executive Medical Plan) other than in
connection with an across-the-board reduction similarly affecting substantially
all senior executives of the Company, or (iv) any material breach by the Company
of any provision of this Agreement without the Executive having committed any
material breach of the Executive's obligations hereunder or under the Lydall
Employee Agreement which breach is not cured within thirty days following
written notice thereof to the Company of such breach. In addition, in the case
of a termination of employment within 12 months following a "Change of Control"
(as defined in Section 10), Good Reason shall also include the relocation of the
Executive's office location to a location more than 50 miles away from the
Executive's then current principal place of employment. If an event constituting
a ground for termination of employment for Good Reason occurs, and the Executive
fails to give notice of termination within 90 days after the occurrence of such
event, the Executive shall be deemed to have waived her right to terminate
employment for Good Reason in connection with such event (but not for any other
event for which the 90-day period has not expired).

            (b) Other. The Executive may terminate her employment at any time
and for any reason, other than pursuant to subsection (a) above, by giving the
Company a written notice of termination to that effect at least 30 days before
the date of termination (or such lesser notice period as the Company may agree
to); provided, however, that the Company following receipt of such notice from
the Executive may elect to have the Executive's employment terminate immediately
following its receipt of such notice. In the event of the Executive's
termination of her employment pursuant to this subsection (b), the Executive
shall be entitled to receive only (i) her base salary pursuant to Section 3.1
earned through the date of such termination of employment plus her base salary
for the period of vacation time earned but not taken for the year of termination
of employment, such base salary to be paid at the normal time for payment of
such base salary, (ii) any other compensation and benefits to the extent
actually earned by the Executive under any other benefit plan or program of the
Company as of the date of such termination of employment, such compensation and
benefits to be paid at the normal time for payment of such compen-

<PAGE>
                                      -7-

sation and benefits, and (iii) any reimbursement amounts owing under Section 4.

            7. Termination of Employment By Death. In the event of the death of
the Executive during the course of her employment hereunder, the Executive's
estate (or other person or entity having such entitlement pursuant to the terms
of the applicable plan or program) shall be entitled to receive (i) the
Executive's base salary pursuant to Section 3.1 earned through the date of the
Executive's death plus the Executive's base salary for the period of vacation
time earned but not taken for the year of the Executive's death, such base
salary to be paid at the normal time for payment of such base salary, (ii) a
bonus for the year of the Executive's death (to be paid within 90 days after the
Executive's death) in an amount equal to a pro rata portion of the average of
the three highest annual bonuses earned by the Executive under the Company's
annual incentive bonus plan for any of the five calendar years preceding the
calendar year of the Executive's death (or, if the Executive was not eligible
for a bonus for at least three calendar years in such five-year period, then the
average of such bonuses for all of the calendar years in such five-year period
for which the Executive was eligible), with any deferred bonuses counting for
the year earned rather than the year paid and with the pro rata portion being
determined by dividing the number of days of the Executive's employment during
such calendar year up to her death by 365 (366 if a leap year), (iii) any other
compensation and benefits to the extent actually earned by the Executive under
any other benefit plan or program of the Company as of the date of such
termination of employment, such compensation and benefits to be paid at the
normal time for payment of such compensation and benefits, and (iv) any
reimbursement amounts owing under Section 4. In addition, in the event of such
death, the Executive's beneficiaries shall receive any death benefits owed to
them under the Company's employee benefit plans. If the Executive's spouse
and/or dependent children elect to continue coverage under the Company's health
plan following the Executive's death pursuant to COBRA, the Company for a period
of 12 months following the Executive's death will pay the same percentage of the
premium for COBRA coverage for the Executive's spouse and/or dependent children,
as applicable, as the Company would have paid in respect of the Executive's
coverage under such plan if the Executive had continued in employment with the
Company for such period.

            8. Benefits Upon Termination Without Cause or For Good Reason (No
Change of Control). If (a) the Executive's em-

<PAGE>
                                      -8-

ployment hereunder shall terminate (i) because of termination by the Company
other than for Cause or Permanent and Total Disability pursuant to Section 5.1,
or (ii) because of termination by the Employee for Good Reason pursuant to
Section 6(a), and (b) such termination of employment does not occur within 12
months following a "Change of Control" of the Company (as defined in Section
10), the Executive shall be entitled to the following:

            (a) The Company shall pay to the Executive her base salary pursuant
      to Section 3.1 earned through the date of such termination of employment
      and any other compensation and benefits to the extent actually earned by
      the Executive under any benefit plan or program of the Company as of the
      date of such termination of employment, such base salary, compensation and
      benefits to be paid at the normal time for payment of such base salary,
      compensation and benefits.

            (b) The Company shall pay the Executive any reimbursement amounts
      owing under Section 4.

            (c) The Company shall pay to the Executive in equal installments
      spread over the period of 12 months beginning on the date of the
      Executive's termination of employment an amount equal in the aggregate to
      the sum of (i) the Executive's annual rate of base salary immediately
      preceding her termination of employment, and (ii) the average of her
      annual bonuses earned under the Company's annual incentive bonus plan for
      the three calendar years preceding her termination of employment (or, if
      the Executive was not eligible for a bonus in each of those three calendar
      years, then the average of such bonuses for all of the calendar years in
      such three-year period for which she was eligible), with any deferred
      bonuses counting for the year earned rather than the year paid. Such
      installments shall be paid at the times that salary payments are normally
      made by the Company.

            (d) If the Executive elects to continue coverage under the Company's
      health plan pursuant to COBRA, then for the period beginning on the date
      of the Executive's termination of employment and ending on the earlier of
      (i) the date which is 12 months after the date of such termination of
      employment or (ii) the date on which the Executive commences substantially
      full-time employment as an employee of an employer that offers health
      benefits, the Company will pay the same percentage of the Executive's
      premium

<PAGE>
                                      -9-

      for COBRA coverage for the Executive and, if applicable, her spouse and
      dependent children, as the Company paid at the applicable time for
      coverage under such plan for actively employed senior executives
      generally. In addition, for the period beginning on the date of the
      Executive's termination of employment and ending on the earlier of (i) the
      date which is 12 months after the date of such termination of employment
      or (ii) the date on which the Executive commences substantially full-time
      employment as an employee of an employer that offers life insurance
      benefits, the Company will continue to provide the life insurance benefits
      that the Company would have provided to the Executive if the Executive had
      continued in employment with the Company for such period, but only if the
      Executive timely pays the portion of the premium for such coverage that
      senior executives of the Company generally are required to pay for such
      coverage, if any. The Executive shall notify the Company promptly if she,
      while eligible for benefits under this subsection (d), commences
      substantially full-time employment as an employee of an employer that
      offers health and/or life insurance benefits.

            (e) The Company will provide the Executive with outplacement
      services selected by the Executive, at the Company's expense not to exceed
      $10,000.

            9. Benefits Upon Termination Without Cause or For Good Reason
(Change of Control). If (a) the Executive's employment hereunder shall terminate
(i) because of termination by the Company other than for Cause or Permanent and
Total Disability pursuant to Section 5.1, or (ii) because of termination by the
Employee for Good Reason pursuant to Section 6(a), and (b) such termination of
employment occurs within 12 months following a "Change of Control" of the
Company (as defined in Section 10), the Executive shall be entitled to the
following:

            (a) The Company shall pay to the Executive her base salary pursuant
      to Section 3.1 earned through the date of such termination of employment
      and any other compensation and benefits to the extent actually earned by
      the Executive under any benefit plan or program of the Company as of the
      date of such termination of employment, such base salary, compensation and
      benefits to be paid at the normal time for payment of such base salary,
      compensation and benefits.

            (b) The Company shall pay the Executive any reimbursement amounts
      owing under Section 4.

<PAGE>
                                      -10-

            (c) The Company shall pay to the Executive as a severance benefit an
      amount equal to two (2) times the sum of (i) her annual rate of base
      salary immediately preceding her termination of employment, and (ii) the
      average of her three highest annual bonuses earned under the Company's
      annual incentive bonus plan for any of the five calendar years preceding
      her termination of employment (or, if the Executive was not eligible for a
      bonus for at least three calendar years in such five-year period, then the
      average of such bonuses for all of the calendar years in such five-year
      period for which the Executive was eligible), with any deferred bonuses
      counting for the year earned rather than the year paid. Such severance
      benefit shall be paid in a lump sum within 30 days after the date of such
      termination of employment.

            (d) The Company shall pay to the Executive as a bonus for the year
      of termination of her employment an amount equal to a portion (determined
      as provided in the next sentence) of the Executive's maximum bonus
      opportunity under the Company's annual incentive bonus plan for the
      calendar year of termination of the Executive's employment or, if none,
      such portion of the bonus awarded to the Executive under the Company's
      annual incentive bonus plan for the calendar year immediately preceding
      the calendar year of the termination of her employment, with deferred
      bonuses counting for the year earned rather than the year paid. Such
      portion shall be determined by dividing the number of days of the
      Executive's employment during such calendar year up to her termination of
      employment by 365 (366 if a leap year). Such payment shall be made in a
      lump sum within 30 days after the date of such termination of employment,
      and the Executive shall have no right to any further bonuses under said
      plan.

            (e) During the period of 24 months beginning on the date of the
      Executive's termination of employment, the Executive (and, if applicable,
      the Executive's spouse and dependent children) shall remain covered by the
      medical, dental, life insurance, and, if reasonably commercially available
      through nationally reputable insurance carriers, long-term disability
      plans of the Company that covered the Executive immediately prior to her
      termination of employment as if the Executive had remained in employment
      for such period; provided, however, that the coverage under any such plan
      is conditioned on the timely payment by the Executive (or her spouse or
      dependent children) of the portion of the premium for such coverage that
      actively em-

<PAGE>
                                      -11-

      ployed senior executives with the Company generally are required to pay
      for such coverage. In the event that the Executive's participation in any
      such plan is barred, the Company shall arrange to provide the Executive
      (and, if applicable, her spouse and dependent children) with substantially
      similar benefits (but, in the case of long-term disability benefits, only
      if reasonably commercially available).

            (f) The Company shall supplement the benefits payable in respect of
      the Executive under the Company's Pension Plan and Supplemental Executive
      Retirement Plan (and any successor plans thereto) (collectively, the
      "Pension Plans") by paying the difference between (i) the benefits that
      the Executive would have been entitled to receive under the Pension Plans
      if she had been credited with two additional years of service (but no
      additional years of age) for purposes of the benefit accrual formula under
      the Pension Plans as of the date of termination of the Executive's
      employment and (ii) the benefits that the Executive is entitled to receive
      under the Pension Plans determined without regard to this subsection (f).
      Such benefits shall be payable in the same form and at the same time as
      the benefits under the respective Pension Plans.

            (g) Each stock option granted by the Company to the Executive and
      outstanding immediately prior to termination of her employment shall be
      fully vested and immediately exercisable and may be exercised by the
      Executive (or, following her death, by the person or entity to which such
      option passes) at any time prior to the expiration date of the applicable
      option (determined without regard to any earlier termination of the option
      that would otherwise occur by reason of termination of her employment).
      Each restricted stock award granted by the Company to the Executive and
      outstanding immediately prior to termination of the Executive's employment
      shall be fully vested upon such termination of employment.

            (h) The Company will provide the Executive with out-placement
      services selected by the Executive, at the Company's expense not to exceed
      $10,000.

            (i) The Company shall promptly pay all reasonable attorneys' fees
      and related expenses incurred by the Executive in seeking to obtain or
      enforce any right or benefit under this Agreement or to defend against any
      claim or

<PAGE>
                                      -12-

      assertion in connection with this Agreement, but only to the extent the
      Executive substantially prevails.

            10. Change of Control. For the purposes of this Agreement, a "Change
of Control" shall be deemed to have occurred if (a) any person or persons acting
together which would constitute a "group" for purposes of Section 13(d) of the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), (other than
the Company or any subsidiary of the Company) shall beneficially own (as defined
in Rule 13d-3 of the Exchange Act), directly or indirectly, at least 25% of the
total voting power of all classes of capital stock of the Company entitled to
vote generally in the election of the Board; (b) Current Directors (as herein
defined) shall cease for any reason to constitute at least a majority of the
members of the Board (for this purpose, a "Current Director" shall mean any
member of the Board as of the date hereof and any successor of a Current
Director whose election, or nomination for election by the Company's
shareholders, was approved by at least a majority of the Current Directors then
on the Board); (c) the shareholders of the Company approve (i) a plan of
complete liquidation of the Company or (ii) an agreement providing for the
merger or consolidation of the Company other than a merger or consolidation in
which (x) the holders of the common stock of the Company immediately prior to
the consolidation or merger have, directly or indirectly, at least a majority of
the common stock of the continuing or surviving corporation immediately after
such consolidation or merger or (y) the Board immediately prior to the merger or
consolidation would, immediately after the merger or consolidation, constitute a
majority of the board of directors of the continuing or surviving corporation;
or (d) the shareholders of the Company approve an agreement (or agreements)
providing for the sale or other disposition (in one transaction or a series of
transactions) of all or substantially all of the assets of the Company.

            11. Golden Parachute Excise Tax.

            (a) In the event that any payment or benefit received or to be
received by the Executive pursuant to this Agreement or any other plan, program
or arrangement of the Company or any of its affiliates would constitute an
"excess parachute payment" within the meaning of Section 280G of the Internal
Revenue Code of 1986, as amended (the "Code"), then the payments under this
Agreement shall be reduced (by the minimum possible amounts) until no amount
payable to the Executive under this Agreement constitutes an "excess parachute
payment" within the meaning of Section 280G of the Code; provided, how-

<PAGE>
                                      -13-

ever, that no such reduction shall be made if the net after-tax payment (after
taking into account Federal, state, local or other income and excise taxes) to
which the Executive would otherwise be entitled without such reduction would be
greater than the net after-tax payment (after taking into account Federal,
state, local or other income and excise taxes) to the Executive resulting from
the receipt of such payments with such reduction. If, as a result of subsequent
events or conditions (including a subsequent payment or absence of a subsequent
payment under this Agreement or other plan, program or arrangement of the
Company or any of its affiliates), it is determined that payments under this
Agreement have been reduced by more than the minimum amount required to prevent
any payments from constituting an "excess parachute payment", then an additional
payment shall be promptly made to the Executive in an amount equal to the
additional amount that can be paid without causing any payment to constitute an
excess parachute payment.

            (b) All determinations required to be made under this Section 11
shall be made by a nationally recognized independent accounting firm mutually
agreeable to the Company and the Executive (the "Accounting Firm") which shall
provide detailed supporting calculations to the Company and the Executive as
requested by the Company or the Executive. All fees and expenses of the
Accounting Firm shall be borne solely by the Company and shall be paid by the
Company upon demand of the Executive as incurred or billed by the Accounting
Firm. All determinations made by the Accounting Firm pursuant to this Section 11
shall be final and binding upon the Company and the Executive.

            (c) To the extent any payment or benefit is to be reduced pursuant
to this Section 11, the severance payment described in Section 8(c) or 9(c) will
first be reduced, then the bonus described in Section 9(d), and then the
supplemental pension benefits described in Section 9(f), in each case only to
the extent necessary.

            12. Entitlement to Other Benefits. Except as otherwise provided in
this Agreement, this Agreement shall not be construed as limiting in any way any
rights or benefits that the Executive or her spouse, dependents or beneficiaries
may have pursuant to any other plan or program of the Company.

            13. Indemnification. The parties agree to execute a separate
Indemnification Agreement in the form attached as Exhibit B.

<PAGE>
                                      -14-

            14. General Provisions.

            14.1 No Duty to Seek Employment. The Executive shall not be under
any duty or obligation to seek or accept other employment following termination
of employment, and no amount, payment or benefits due to the Executive hereunder
shall be reduced or suspended if the Executive accepts subsequent employment,
except as expressly set forth herein.

            14.2 Deductions and Withholding. All amounts payable or which become
payable under any provision of this Agreement shall be subject to any deductions
authorized by the Executive and any deductions and withholdings required by law.

            14.3 Notices. All notices, demands, requests, consents, approvals or
other communications (collectively "Notices") required or permitted to be given
hereunder or which are given with respect to this Agreement shall be in writing

States mail, registered or certified, return receipt requested, postage prepaid,

                              Attn: Chief Executive Officer

      To the Executive:       Mary A. Tremblay
                              116 Prospect Hill Road
                              Colchester, CT 06415

or such other address as such party shall have specified most recently by
written notice. Notice mailed as provided herein shall be deemed given on the
fifth business day following the date so mailed or on the date of actual
receipt, whichever is earlier.

            14.4 No Disparagement. The Executive shall not during the period of
her employment with the Company, nor during the two-year period beginning on the
date of termination of her employment for any reason, disparage the Company or
any of its subsidiaries or affiliates or any of their shareholders, directors,
officers, employees or agents. The Executive agrees that the terms of this
Section 14.4 shall survive the term of this Agreement and the termination of the
Executive's employment.

<PAGE>
                                      -15-

            14.5 Proprietary Information and Inventions. The Lydall Employee
Agreement previously executed by the Executive and attached hereto as Exhibit A
is incorporated by reference in this Agreement, and the Executive agrees to
continue to be bound thereby.

            14.6 Covenant to Notify Management. The Executive agrees to abide by
the ethics policies of the Company as well as the Company's other rules,
regulations, policies and procedures. The Executive agrees to comply in full
with all governmental laws and regulations as well as ethics codes applicable.
In the event that the Executive is aware or suspects the Company, or any of its
officers or agents, of violating any such laws, ethics, codes, rules,
regulations, policies or procedures, the Executive agrees to bring all such
actual and suspected violations to the attention of the Company immediately so
that the matter may be properly investigated and appropriate action taken. The
Executive understands that the Executive is precluded from filing a complaint
with any governmental agency or court having jurisdiction over wrongful conduct
unless the Executive has first notified the Company of the facts and permits it
to investigate and correct the concerns.

            14.7 Amendments and Waivers. No provision of this Agreement may be
modified, waived or discharged unless such waiver, modification or discharge is
agreed to in writing signed by the Executive and the Company. No waiver by
either Party hereto at any time of any breach by the other Party hereto of, or
compliance with, any condition or provision of this Agreement to be performed by
such other Party shall be deemed a waiver of similar or dissimilar provisions or
conditions at the same or at any prior or subsequent time.

            14.8 Beneficial Interests. This Agreement shall inure to the benefit
of and be enforceable by a) the Company's successors and assigns and b) the
Executive's personal and legal representatives, executors, administrators,
successors, heirs, distributees, devisees and legatees. If the Executive shall
die while any amounts are still payable to her hereunder, all such amounts,
unless otherwise provided herein, shall be paid in accordance with the terms of
this Agreement to the Executive's devisee, legatee, or other designee or, if
there be no such designee, to the Executive's estate.

            14.9 Successors. The Company will require any successors (whether
direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to assume
expressly and

<PAGE>
                                      -16-

agree to perform this Agreement in the same manner and to the same extent that
the Company would be required to perform.

            14.10 Assignment. This Agreement and the rights, duties, and
obligations hereunder may not be assigned or delegated by any Party without the
prior written consent of the other Party and any attempted assignment or
delegation without such prior written consent shall be void and be of no effect.
Notwithstanding the foregoing provisions of this Section 14.10, the Company may
assign or delegate its rights, duties and obligations hereunder to any affiliate
or to any person or entity which succeeds to all or substantially all of the
business of the Company or one of its subsidiaries through merger, consolation,
reorganization, or other business combination or by acquisition of all or
substantially all of the assets of the Company or one of its subsidiaries.

            14.11 Choice of Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of Connecticut.

            14.12 Statute of Limitations. The Executive and the Company hereby
agree that there shall be a one year statute of limitations for the filing of
any requests for arbitration or any lawsuit relating to this Agreement or the
terms or conditions of Executive's employment by the Company. If such a claim is
filed more than one year subsequent to the Executive's last day of employment it
shall be precluded by this provision, regardless of whether or not the claim has
accrued at that time.

            14.13 Right to Injunctive and Equitable Relief. The Executive's
obligations under Section 14.4 are of a special and unique character, which
gives them a peculiar value. The Company cannot be reasonably or adequately
compensated for damages in an action at law in the event the Executive breaches
such obligations. Therefore, the Executive expressly agrees that the Company
shall be entitled to injunctive and other equitable relief without bond or other
security in the event of such breach in addition to any other rights or remedies
which the Company may possess or be entitled to pursue. Furthermore, the
obligations of the Executive and the rights and remedies of the Company under
Section 14.4 and this Section 14.13 are cumulative and in addition to, and not
in lieu of, any obligations, rights, or remedies as created by applicable law.

            14.14 Severability or Partial Invalidity. The invalidity or
unenforceability of any provisions of this Agree-

<PAGE>
                                      -17-

ment shall not affect the validity or enforceability of any other provision of
this Agreement, which shall remain in full force and effect.

            14.15 Entire Agreement. This Agreement, along with the Lydall
Employee Agreement and the Indemnification Agreement by and between the
Executive and the Company, constitutes the entire agreement of the Parties and
supersedes all prior written or oral and all contemporaneous oral agreements,
understandings, and negotiations between the Parties with respect to the subject
matter hereof. This Agreement may not be changed orally and may only be modified
in writing signed by both Parties. This Agreement, along with the Lydall
Employee Agreement and the Indemnification Agreement, is intended by the Parties
as the final expression of their agreement with respect to such terms as are
included herein and therein and may not be contradicted by evidence of any prior
or contemporaneous agreement. The Parties further intend that this Agreement,
along with the Lydall Employee Agreement and the Indemnification Agreement,
constitutes the complete and exclusive statement of their terms and that no
extrinsic evidence may be introduced in any judicial proceeding involving such
agreements.

            14.16 Counterparts. This Agreement may be executed in any number of
counterparts, each of which when so executed shall be deemed an original but all
of which together shall constitute one and the same instrument.

                                      -18-

            IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed by its duly authorized officer and the Employee has hereunto set her
hand as of the day and year first above written.
