EXECUTIVE EMPLOYMENT AGREEMENT    
  

    This EMPLOYMENT AGREEMENT (the "Agreement") is dated effective as of the 1st day of January, 2001 (the
"Effective Date"), between PolyVision Corporation, a New York corporation (the "Employer") and Michael H. Dunn (the "Executive"). 

 
 

W I T N E S S E T H    
  

    WHEREAS, the Employer and the Executive have previously entered into an employment agreement dated as of
November 20, 1998 (the "Employment Agreement") pursuant to which the Executive is currently employed as Chief Executive Officer of the Employer, and has and will continue to provide services to
the Employer and all of its operational businesses; 

    WHEREAS, the Employer and the Executive desire to amend and restate the Employment Agreement, effective as of the date set forth above;
and 

    WHEREAS, the parties hereto desire to set forth in writing the terms and conditions of their understandings and agreements. 

    NOW THEREFORE, in consideration of the foregoing, of the mutual promises contained herein and of other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 

    1.  POSITION/DUTIES.  

    (a) During
the Employment Term (as hereinafter defined), the Executive shall serve as the Chief Executive Officer of the Employer, with the responsibility and authority
to supervise and direct the management of all the activities of the Employer, any subsidiary thereof or any successor to the Employer in the ordinary course of its business and shall have such
responsibilities, duties and authority as are generally associated with each such position, and, provided that they are not inconsistent with the foregoing, such as are from time to time assigned to
the Executive by the Board of Directors of the Employer (the "Board"). 

    (b) During
the Employment Term (as such term is defined in Section 2 of the Agreement), and excluding any periods of vacation and sick leave to which the
Executive is entitled, the Executive agrees to devote all or substantially all of his full business time, energy and skill in the performance of his duties for the Employer and to perform faithfully
and efficiently such duties. During the Employment Term, it shall not be a violation of this Agreement for the Executive to (A) serve on corporate, civic or charitable boards or committees and
(B) manage personal investments, so long as such activities do not significantly interfere with the performance of the Executive's responsibilities as an employee of the Employer in accordance
with this Agreement and are not competitive with the operating businesses of the Employer. 

    (c) The
Executive agrees to serve without additional compensation, if elected or appointed thereto, as a director of the Employer and any of its subsidiaries and in one
or more executive offices of any of the Employer's subsidiaries, provided that the Executive is indemnified for serving in any and all such capacities. The Employer shall cause the Executive to be
nominated to its Board throughout the Employment Term. 

    2.  EMPLOYMENT TERM.  The Executive's term of employment under this Agreement
(such term of employment is herein referred to as the "Employment Term") shall commence on the Effective Date and shall continue until terminated by either party as provided in Section 8. In no
event, however, shall the Employment Term extend beyond the end of the month in which the Executive's sixty-fifth birthday occurs. 

    3.  BASE SALARY.  During the Employment Term, the Employer agrees to pay the
Executive a base salary ("Base Salary") at an annual rate of not less than $300,000 or such higher rate as may from 

 

time to time by determined by the Board, payable in substantially equal installments in accordance with the normal payroll practices of the Employer. The Executive's Base Salary shall be subject to
annual review by the Board and shall be increased as of each anniversary of the Effective Date pursuant to such review by a percentage no less than the percentage increase in the consumer price index,
as published by the Bureau of Labor Statistics of the U.S. Department of Labor, for the calendar year immediately preceding such review. Any increase in Base Salary shall not serve to limit or reduce
any
other obligation to the Executive under this Agreement. Base Salary shall not be reduced after any such increase and the term Base Salary as utilized in this Agreement shall refer to Base Salary as so
increased. 

    4.  ANNUAL BONUS.  During the Employment Term, in addition to the Base Salary,
the Executive will be eligible to receive an annual bonus (the "Annual Bonus") equal to up to 50% of Base Salary, payable within 90 days following the last day of the Employer's fiscal year for
which the Annual Bonus is awarded. The actual amount of any such Annual Bonus will be determined by the Board (or a designated committee thereof), with such determination to be based upon the
Employer's and the Executive's achievement of budgetary and other objectives, as set by the Board (or designated committee thereof), and upon its discretionary evaluation of the Executive's
performance provided, however, on or after a Change of Control (as defined in Appendix A), the dollar amount of the Annual Bonus shall be at least equal to the Executive's highest cash bonus
under the Employer's annual cash bonus program, or any comparable cash bonus under any predecessor or successor plan, for the last three full fiscal years prior to a Change of Control. 

    5.  EMPLOYEE BENEFITS  

    (a)  WELFARE BENEFITS.  During the Employment Term, the Executive and/or the
Executive's family, as the case may be, shall be eligible for participation in and shall receive all benefits under welfare benefit plans, practices, policies and programs provided by the Employer
(including, without limitation, medical, prescription, dental, disability, salary continuance, employee life, group life, accidental death and travel accident insurance plans and programs) to the
extent applicable generally to the most senior executives of the Employer, but in no event shall such plans, practices, policies and programs provide the Executive with benefits which are materially
less favorable, in the aggregate, than the most favorable of such plans, practices, policies and programs in effect for the Executive as of the date hereof or, if more favorable to the Executive,
those provided generally at any time to any other executive of the Employer. 

    (b)  INCENTIVE, SAVINGS AND RETIREMENT PLANS.  During the Employment Term, the
Executive shall be entitled to participate in all incentive, savings and retirement plans, practices, policies and programs applicable generally to the most senior executives of the Employer. 

    (c)  FRINGE BENEFITS.  During the Employment Term: 

    (i)  The
Employer shall reimburse the Executive for the reasonable expenses incurred by the Executive in undergoing an annual physical examination by a licensed
physician. 

    (ii) The
Employer shall reimburse the Executive for the reasonable expenses incurred by the Executive in connection with obtaining professional tax and financial
planning advice. 

    (iii) The
Employer shall pay, at the direction of the Executive, up to $2,500 per annum on account of premiums for an existing life insurance policy insuring the life
of and owned by the Executive. 

    (d)  VACATION.  During the Employment Term, the Executive shall be entitled to
paid vacation of four weeks per year, any unused portion of which shall be forfeited as of the end of each year. 

2

 

    (e)  EXPENSES.  During the Employment Term, the Executive shall be entitled to
receive prompt reimbursement for all reasonable and customary expenses incurred by the Executive in performing services hereunder, including (i) all expenses of travel and living expenses while
away from home or business or at the request of and in the service of the Employer and (ii) an automobile, plus all reasonable expenses of maintaining and operating the automobile, provided
that all such expenses are accounted for in accordance with the policies and procedures established by the Employer, or a monthly cash allowance in lieu thereof. 

    (f)  DISABILITY OFFSET.  Payments made to the Executive pursuant to this
Section 5 shall be reduced by the sum of the amounts, if any, payable to the Executive at or prior to the time of any such payment under disability benefit plans of the Employer or under the
Social Security disability insurance program, and which amounts were not previously applied to reduce any such payments. 

    6.  STOCK OPTIONS.  

    (a)  GRANT.  As soon as administratively practical following the execution
hereof, the Compensation Committee of the Board shall grant to the Executive an option (the "Option") to purchase 150,000 shares of the Employer's common stock, par value $.001 (the "Common Stock")
under the Employer's Stock Option Plan as may be in effect from time to time (the "Stock Option Plan") at an exercise price equal to the fair market value (as defined in the Stock Option Plan) of the
Common Stock on the Grant Date. The Option shall, to the maximum extent permitted by applicable law, be designated as an incentive stock option within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "Code") and to the extent not allowable, the Option shall be a non-qualified stock option. 

    (b)  VESTING.  The Option shall vest and become exercisable in installments as
provided herein, which shall be cumulative. Subject to the terms in this Section 6, the Option shall vest and become exercisable in equal annual installments of 33% each, on the first, second
and third anniversary of the Effective Date, provided the Executive is employed by the Employer on each such vesting date. In the event of
the Executive's termination of employment (i) by the Executive other than because of death, Disability (as defined below) or Good Reason (as defined below) or (ii) by the Employer for
Cause (as defined below), all stock options to purchase shares of Common Stock (including, without limitation, the Option) not theretofore exercisable will lapse and be forfeited. In the event the
Executive's employment is terminated for any other reason, including, without limitation, a termination because of death or Disability, Good Reason or without Cause, all stock options to purchase
shares of Common Stock (including, without limitation, the Option) not theretofore exercisable will thereupon become exercisable. 

    (c)  FORM OF OPTION.  The Option shall be granted pursuant to and, to the extent
not contrary to the terms of this Agreement, shall be subject to all of the terms and conditions imposed under the Employer's standard stock option agreement and the Stock Option Plan or any other
stock option plan sponsored by the Employer. 

    (d)  DISCRETIONARY GRANTS.  In addition to the Option grants, at the sole
discretion of the Board (or a duly authorized committee thereof), the Executive shall be eligible for additional annual grants of stock options commencing on January 2, 2002. 

    7.  RESTRICTED STOCK.  

    (a)  GRANT.  As soon as administratively practical following the execution
hereof, the Compensation Option Committee of the Board will grant to the Executive 40,000 restricted shares of Common Stock, which restricted shares shall be set aside in the custody, control and
possession of the Employer and will be released to the Executive at the rate of 25% on January 15, 2002, 25% on February 15, 2003 and 50% on February 15, 2004. In the event of the
Executive's termination of employment prior to the third anniversary of the Effective Date (i) by the Executive other than because 

3

 

of death, Disability (as defined below) or Good Reason or (ii) by the Employer for Cause, then the scheduled releases on any subsequent anniversary shall be cancelled and all restricted shares
of Common Stock not theretofore released shall be forfeited by the Executive and shall be cancelled and retired by the Employer. In the event the Executive's employment is terminated for any other
reason prior to the third anniversary of the Effective Date, including, without limitation, a termination because of death or Disability, Good Reason or without Cause, all restricted shares of Common
Stock granted pursuant to this Section 7(a) not theretofore released shall thereupon become released. The Executive recognizes and understands that the restricted securities provided for
hereunder will bear a restrictive legend reflecting the foregoing restrictions and that such securities have not been registered under the Securities Act of 1933. 

    (b)  TAX LOAN.  Not less than 10 days prior to the due date of the
Executive's federal income tax return for every taxable year of the Executive in which his income tax liability is increased by or as a result of the grant of restricted shares of Common Stock
pursuant to Section 7(a) hereof, the Employer shall lend to the Executive an amount equal to such increased tax liability. The Employer and the Executive shall enter into an appropriate
agreement providing for the repayment by the Executive of such loan, which agreement shall provide that (i) if the principal amount of such loan (together with the aggregate outstanding amount
of other loans between the Employer and the Executive) exceeds the de minimis amount set forth in Section 7872(c)(3) of the Code (or any
successor provision thereof), then such loan shall bear interest at a rate not less than the applicable Federal rate determined in accordance with Section 7872(f)(2) of the Code (or any
successor provision thereof) and (ii) if the Executive disposes of any of the shares of restricted Common Stock prior to the third anniversary of the date any loan is advanced to the Executive
pursuant to this Section 7(b), the principal balance of the loan shall become immediately due and payable in cash or shares of Common Stock owned by the Executive for a period of at least six
months or such other period necessary to avoid a charge, for accounting purposes, against the Employer's earnings as reported in the Employer's financial statements. The Compensation Committee of the
Board will approve the delivery of previously owned shares of Common Stock held for at least six months by the Executive to satisfy his obligation to repay the loan advanced to the Executive pursuant
to this Section 7(b). 

    8.  TERMINATION.  The Executive's employment and the Employment Term shall
terminate without any breach of this Agreement on the first of the following to occur: 

    (a)  DISABILITY.  Upon 90 days' written notice by the Employer to the
Executive of termination due to Disability during the Employment Term, provided that, within the 90 days after such receipt, the Executive shall not have returned to full-time
performance of the Executive's duties. For purposes of this Agreement, "Disability" shall mean the absence of the Executive from the Executive's duties with the Employer on a full-time
basis for 180 consecutive days (or such shorter period as will suffice for the Executive to qualify for full disability benefits under the applicable disability insurance policy or policies of the
Employer) as a result of incapacity due to mental or physical illness which is determined to be total and permanent by a physician selected by the Employer or its insurers and reasonably acceptable to
the Executive or the Executive's legal representative. 

    (b)  DEATH.  Automatically on the date of death of the Executive during the
Employment Term. 

    (c)  CAUSE.  Immediately upon written notice by the Employer to the Executive of
a termination for Cause during the Employment Term provided, such notice is given within 90 days of the Board's discovery of the Cause event. For purposes of this Agreement, "Cause" shall mean: 

    (i)  the
willful and continued failure of the Executive to perform substantially the Executive's duties pursuant to this Agreement (other than any such failure
resulting from incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to the Executive by the Board which specifically identifies the manner in
which the Board believes that the Executive has not substantially performed the Executive's duties; or 

4

 

    (ii) the willful engaging by the Executive in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Employer. 

For
purposes of this provision, no act or failure to act, on the part of the Executive, shall be considered "willful" unless it is done, or omitted to be done, by the Executive in bad faith or without
reasonable belief that the Executive's action or omission was in the best interests of the Employer. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the
Board or based upon the advice of counsel for the Employer shall be conclusively presumed to be done, or omitted to be done, by the Executive in good faith and in the best interests of the Employer.
The cessation of employment of the Executive shall not be deemed to be for Cause unless and until there shall have been delivered to the Executive a copy of a resolution duly adopted by the
affirmative vote of not less than a majority of the entire membership of the Board at a meeting of the Board called and held for such purpose (after reasonable notice is provided to the Executive and
the Executive is given an opportunity, together with counsel, to be heard before the Board), finding that, in the good faith opinion of the Board, the Executive is guilty of the conduct described in
subparagraph (i) or (ii) above, and specifying the particulars thereof in detail. 

    (d)  WITHOUT CAUSE.  Upon 60 days' written notice by the Employer to the
Executive of an involuntary termination without Cause during the Employment Term. 

    (e)  GOOD REASON.  Upon written notice by the Executive to the Employer of a
termination for Good Reason during the Employment Term provided, such notice is given within 90 days of the Executive's discovery of the Good Reason event. For purposes of this Agreement, "Good
Reason" shall mean: 

    (i)  the
assignment to the Executive of any duties materially inconsistent with the Executive's position (including status, titles and reporting requirements),
authority, duties or responsibilities as contemplated by Section 1(a) of this Agreement, or any other action by the Employer which results in a material diminution in such position, authority,
duties or responsibilities, excluding for this purpose isolated and inadvertent action(s) not taken in bad faith and remedied by the Employer promptly after receipt of notice thereof given by the
Executive; provided that during any Transition Period (as defined in Section 9(a)), Good Reason shall include any assignment of duties inconsistent with the Executive's position or any
diminution (whether or not material); 

    (ii) any
material failure by the Employer to comply with any of the provisions of Sections 3, 4, 5, 6, 7, 9, 10 or 11 of this Agreement or any other failure with regard
to a material provision of this Agreement, other than isolated and inadvertent failure(s) not occurring in bad faith and remedied by the Employer promptly after receipt of notice thereof given by the
Executive; provided that during any Transition Period, Good Reason shall include any failure (whether or not material); 

    (iii) any
termination by the Employer of the Executive's employment otherwise than as expressly permitted by this Agreement; 

    (iv) any
failure by the Employer to comply with and satisfy Section 16(a) of this Agreement; 

    (v) during
any Transition Period, any failure of the Employer to continue in effect any health or welfare plan, employee benefit plan, pension plan, fringe benefit
plan, vacation or compensation plan, arrangement or program in which the Executive (and eligible dependents) are participating at any time during the 120-day period immediately preceding
the Change of Control or, if more favorable to the Executive, those provided generally at any time after the Change of Control to any other executive of the Employer and their beneficiaries, unless
the Executive (and eligible dependents) are permitted to participate in other plans providing the Executive (and eligible dependents) with substantially comparable benefits at no greater
after-tax cost to the Executive (and eligible dependents), or the taking of any action by the Employer which would adversely 

5

 

affect the Executive's (and eligible dependents) participation in or reduce the Executive's (and eligible dependents) benefits under any such plan; 

    (vi) during
any Transition Period, any failure of the Employer to provide the Executive with an office or offices of a size and with furnishings and other appointments,
and to personal secretarial and other assistance, at least equal to the most favorable of the foregoing provided to the Executive by the Employer at any time during the 120-day period
immediately preceding the Change of Control or, if more favorable to the Executive, those provided generally at any time after the Change of Control to any other executive (except for the Chief
Executive Officer) of the Employer; or 

    (vii) any
termination by the Executive during the 30-day period immediately following the date which is six months after any Change of Control. 

    During
any Transition Period, any good faith determination of "Good Reason" made by the Executive shall be conclusive. 

    (f)  WITHOUT GOOD REASON.  Upon 120 days' written notice by the Executive
to the Employer of the Executive's voluntary termination of employment without Good Reason (which the Employer may, in its sole discretion, make effective earlier than any notice date). 

    (g)  NOTICE OF TERMINATION.  Any termination of the Executive's employment by the
Employer or by the Executive (other than termination by reason of the Executive's death) shall be communicated by written Notice of Termination to the other party hereto in accordance with
Section 17 hereof. For purposes of this Agreement, a "Notice of Termination" means a written notice which (i) indicates the specific termination provision in this Agreement relied upon
(ii) other than in connection with a termination pursuant to Section 8(d), to the extent applicable, sets forth in reasonable detail the facts and circumstances claimed to provide a
basis for termination of the Executive's employment under the provision so indicated and (iii) if the date of termination is other than the date of receipt of such notice, specifies the
termination date. The good faith failure by the Executive or the Employer to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Good Reason or Cause
shall not waive any right of the Executive or the Employer, respectively, hereunder or preclude the Executive or the Employer, respectively, from asserting such fact or circumstance in enforcing the
Executive's or the Employer's rights hereunder. If within 30 days after any Notice of Termination is given the party receiving such Notice of Termination notifies the other party that a good
faith dispute exists concerning the termination, the date of termination shall be the date on which the dispute is finally determined, either by mutual written agreement of the parties, (or if agreed
to by the parties) by a binding and final arbitration award or by a final judgment, order or decree of a court of competent jurisdiction (the time for appeal therefrom having expired and no appeal
having been perfected). 

    9.  COMPENSATION UPON TERMINATION.  

    (a)  COMPENSATION UPON TERMINATION FOR DISABILITY.  If the Executive's employment
by the Employer is terminated by reason of the Executive's Disability during the Employment Term, the Employer shall pay or provide the Executive the sum of (i) the Executive's Base Salary
through the date of termination to the extent not theretofore paid, (ii) the product of (x) the Annual Bonus paid or payable, including any bonus or portion thereof which has been earned
but deferred, for the most recently completed fiscal year during the Employment Term, if any, (the "Annual Bonus Amount"), multiplied by (y) a fraction, the numerator of which is the number of
days in the current fiscal year through the date of termination, and the denominator of which is 365, (iii) any compensation previously deferred by the Executive (together with any accrued
interest or earnings thereon) and any accrued vacation pay, in each case to the extent not theretofore paid and (iv) reimbursement for any unreimbursed expenses incurred through the date of
termination (the sum 

6

 

of the amounts described in clauses (i), (ii), (iii) and (iv)) shall be referred to in this Agreement as the "Accrued Obligations"). The Accrued Obligations shall be paid to the Executive in a
lump sum in cash within 30 days of the date of termination. 

    In
addition, to the extent not theretofore paid or provided, the Employer shall timely pay or provide to the Executive's legal representatives any other amounts or benefits required
to be paid or provided or which the Executive is eligible to receive under any plan, program, policy or practice or contract or
agreement of the Employer (such other amounts and benefits shall be referred to in this Agreement as the "Other Benefits"). Notwithstanding the foregoing, if the Executive's employment by the Employer
is terminated by reason of the Executive's Disability during the period commencing six months prior to a Change of Control and ending on the third anniversary of a Change of Control (the "Transition
Period"), the term "Other Benefits" shall include, and the Executive shall be entitled after the date of termination to receive, disability and other benefits at least equal to the most favorable of
those generally provided by the Employer to disabled executives and/or their families in accordance with such plans, programs, practices and policies relating to disability, if any, as in effect
generally with respect to the most senior executives and their families at any time during the 120-day period immediately preceding the Change of Control or, if more favorable to the
Executive and/or the Executive's family, as in effect at any time thereafter generally with respect to any other executive of the Employer and their families. 

    Notwithstanding
the foregoing, the Employer shall maintain, at the Employer's sole expense, in full force and effect, for the continued benefit of the Executive for 12 months
following the date of termination, all employee welfare benefit plans and programs in which the Executive was entitled to participate immediately prior to the date of termination provided that the
Executive's continued participation is possible under the general terms and provisions of such plans and programs ("Continued Welfare Benefits"). In the event that the Executive's participation in any
such plan or program is barred, the Employer shall arrange to provide the Executive with benefits substantially similar to those which the Executive would otherwise have been entitled to receive under
such plans and programs from which his continued participation is barred. 

    (b)  COMPENSATION UPON TERMINATION FOR DEATH.  If the Executive's employment by
the Employer is terminated by reason of the Executive's death during the Employment Term, the Employer shall (i) pay the Accrued Obligations and an amount equal to the sum of the Executive's
Base Salary in effect immediately prior to termination and the Annual Bonus Amount to the Executive's legal representatives in a lump sum in cash within 30 days of the date of termination;
(ii) timely pay or provide the Other Benefits; and (iii) timely pay or provide the Continued Welfare Benefits for twelve months following the date of termination of employment.
Notwithstanding the foregoing, if the Executive's employment by the Employer is terminated by reason of the Executive's death during the Transition Period, the term Other Benefits shall include,
without limitation, and the Executive's estate and/or beneficiaries shall be entitled to receive, benefits at least equal to the most favorable benefits provided by the Employer to the estates and
beneficiaries of the most senior executives of the Employer under such plans, programs, practices and policies relating to death benefits, if any, as in effect with respect to the most senior
executives and their beneficiaries at any time during the 120-day period immediately preceding the Change of Control or, if more favorable to the Executive's estate and/or the Executive's
beneficiaries, as in effect on the date of the Executive's death with respect to any other executive of the Employer and their beneficiaries. 

    (c)  COMPENSATION UPON TERMINATION FOR CAUSE.  If the Executive's employment is
terminated for Cause during the Employment Term, this Agreement shall terminate without further obligation to the Executive, except that the Employer shall pay or provide the Executive the sum of
(i) the Executive's Base Salary through the date of termination, (ii) the amount of any compensation previously deferred by the Executive and (iii) Other Benefits, in each case to
the extent theretofore unpaid. 

7

 

    (d)  COMPENSATION UPON TERMINATION WITHOUT GOOD REASON.  If the Executive's
employment is terminated by the Executive without Good Reason during the Employment Term, this Agreement shall terminate without further obligation to the Executive, except that the Employer shall
(i) pay the Accrued Obligations to the Executive in a lump sum in cash within 30 days of the date of termination; and (ii) timely pay or provide the Other Benefits. 

    (e)  COMPENSATION UPON TERMINATION WITHOUT CAUSE OR FOR GOOD REASON.  If the
Executive's employment by the Employer is terminated by the Employer other than for Cause in accordance with Section 8(d) hereof or by the Executive for Good Reason in accordance with
Section 8(e) hereof (i) the Employer shall pay to the Executive a lump sum in cash within 30 days of the date of termination in an amount equal to (x) the sum of
(1) the Base Salary in effect immediately prior to termination and (2) the greater of the Annual Bonus paid or payable, including any bonus or portion thereof which has been earned but
deferred, for the most recently completed fiscal year during the Employment Term, multiplied by one and one-half, plus (y) the Accrued Obligations; (ii) the Employer shall
timely pay or provide the Other Benefits; and (iii) the Employer shall continue to comply with its obligations under Section 7(b) without regard to such termination. 

    (f)  COMPENSATION UPON TERMINATION WITHOUT CAUSE OR FOR GOOD REASON FOLLOWING A CHANGE OF
CONTROL.  If the Executive's employment by the Employer is terminated by the Employer without Cause or by Executive for Good Reason at any time during the
Transition Period (as defined in Section 9(a)), then the Employer shall pay or provide the Executive with the following payments and benefits as soon as practical following the later of the
date of the Executive's termination or the date of the Change of Control but in no event later than 30 days following the Change of Control (except as specifically otherwise provided herein): 

    (i)  the
Employer shall pay to the Executive in a lump sum in cash within 30 days after the date of termination the aggregate of the following amounts: 

    (A) Accrued
Obligations; 

    (B) a
lump sum cash payment equal to three times the sum of (x) Executive's Base Salary in effect immediately prior to termination and (y) the highest
Annual Bonus paid or payable to the Executive during the three full fiscal years prior to the Change of Control; and 

    (C) an
amount equal to the excess of (x) the actuarial equivalent of the benefit under the Employer's defined benefit retirement plans, including any excess or
supplemental retirement plan in which the
Executive participates (if any) (together, the "Retirement Plans") (utilizing actuarial assumptions no less favorable to the Executive than those in effect under the Retirement Plans immediately prior
to the Change of Control), which the Executive would receive if the Executive's employment continued for three years after the date of termination assuming for this purpose that all accrued benefits
are fully vested, and, assuming that the Executive's compensation in each of the three years is that required by Sections 3 and 4, reduced by (y) the actuarial equivalent of the Executive's
actual benefit (paid or payable), if any, under the Retirement Plans as of the date of termination. 

    (ii) for
three years after the Executive's date of termination, or such longer period as may be provided by the terms of the appropriate plan, program, practice or
policy, the Employer shall continue benefits to the Executive and/or the Executive's family at least equal to those which would have been provided to them in accordance with the plans, programs,
practices and policies described in Section 5(a) of this Agreement if the Executive's employment had not been terminated or, if more favorable to the Executive, as in effect generally at any
time thereafter with respect to any other executive of the Employer and their families, provided, however, that if the Executive becomes reemployed with another employer and is eligible to receive
medical or other welfare benefits under another employer provided plan, the medical and other welfare benefits 

8

 

described herein shall be secondary to those provided under such other plan during such applicable period of eligibility. For purposes of determining eligibility (but not the time of commencement of
benefits) of the Executive for retiree benefits pursuant to such plans, practices, programs and policies, the Executive shall be considered to have remained employed until three years after the date
of termination and to have retired on the last day of such period; 

    (iii) the
Employer shall, at its sole expense as incurred, provide the Executive with outplacement services the scope and provider of which shall be selected by the
Executive in his sole discretion, and which shall include the provision of reasonable office space and secretarial assistance for the Executive; 

    (iv) timely
pay or provide the Other Benefits; 

    (v) the
Employer shall cause all stock options to purchase shares of Common Stock (including, without limitation, the Option) and restricted shares of Common Stock held
by or for the benefit of the Executive to become immediately fully vested and/or exercisable upon the occurrence of a Change of Control; 

    (vi) the
Employer shall forgive all outstanding indebtedness of the Executive to the Employer under any loan arrangements or agreements entered into by the Employer and
the Executive pursuant to Section 7(b) hereof; and 

    (vii) notwithstanding
anything to the contrary in subparagraph (ii) above, for three years after the Executive's date of termination, Executive shall be
entitled, consistent with past practice, to receive prompt reimbursement for the reasonable and customary expenses incurred by the Executive for an automobile, plus all expenses of maintaining and
operating the automobile, provided that all such expenses are accounted for in accordance with the policies and procedures established by the Employer, or a monthly cash allowance in lieu thereof. 

    10.  EXCISE TAX.  In the event that the Executive becomes entitled to payments
and/or benefits which would constitute "parachute payments" within the meaning of Section 280G(b)(2) of the Code, the provisions of Exhibit B shall apply. 

    11.  STOCK OPTIONS AND COMPANY STOCK.  

    (a) In
the event of the Executive's death, whether his death occurs during or after the Employment Term, all unexercised and exercisable stock options to purchase
shares of Common Stock (including, without limitation, the Option) will be assigned to his estate. 

    (b) In
the event of the termination of the employment of the Executive for any reason, all unexercised and exercisable stock options (including, without limitation, the
Option) must be exercised by him, or his estate (or heir(s)) as the case may be, before the second anniversary of the termination of his employment, but in no event after the tenth anniversary of the
date of grant thereof, and any such stock options not exercised by that date will lapse immediately thereafter. 

    (c) In
the event of any change in the number of issued shares of Common Stock resulting from a subdivision or consolidation of shares or other capital adjustment, or
the payment of a stock dividend, or other increase or decrease in such shares, then appropriate adjustments in the terms of any unexercised stock options shall be made by the Compensation Committee of
the Board. 

    12.  NON-EXCLUSIVITY OF RIGHTS.  Nothing in this Agreement shall
prevent or limit the Executive's continuing or future participation in any plan, program, policy or practice provided by the Employer and for which the Executive may qualify, nor, subject to
Section 21, shall anything herein limit or otherwise affect such rights as the Executive may have under any contract or agreement with the Employer. Amounts which are vested benefits or which
the Executive is otherwise entitled to receive under any plan, policy, practice or program of or any contract or agreement with the Employer 

9

 

at or subsequent to the date of termination shall be payable in accordance with such plan, policy, practice or program or contract or agreement except as explicitly modified by this Agreement. 

    13.  LEGAL FEES.  Following any termination of the Executive's employment that
gives rise to a right to payments and benefits under Section 9(f) or, during the Transition Period, Sections 9(a) or 9(b), the Employer shall pay as incurred, to the full extent permitted by
law, all legal fees and expenses which the Executive may reasonably incur as a result of any contest (regardless of the outcome thereof) by the Employer, the Executive or others of the validity or
enforceability of, or liability under, any provision of this Agreement or any guarantee of performance thereof (including as a result of any contest by the Executive about the amount of any payment
pursuant to this Agreement), plus in each case interest on any delayed payment at the applicable Federal rate provided for in Section 7872(f)(2)(A) of the Code. 

    14.  NONCOMPETITION AND CONFIDENTIALITY.  

    (a) So
long as the Executive is employed by the Employer under this Agreement and unless this Agreement is terminated for any reason, the Executive agrees not to enter
into competitive endeavors. 

    (b) During
the Employment Term and any period thereafter during which or in respect of which the Executive receives payments from the Employer under Section 9,
the Executive shall hold in a fiduciary capacity for the benefit of the Employer all secret or confidential information, knowledge or data relating to the Employer, and their respective businesses,
which shall have been obtained by the Executive during the Executive's employment by the Employer and which shall not be or become public knowledge (other than by acts by the Executive or
representatives of the Executive in violation of this Agreement). After termination of the Executive's employment with the Employer, the Executive shall not, without the prior written consent of the
Employer or as may otherwise be required by law or legal process, communicate or divulge any such information, knowledge or data to anyone other than the Employer and those designated by it. In no
event shall an asserted violation of the provisions of this Section 14 constitute a basis for deferring or withholding any amounts otherwise payable to the Executive under Section 9(f)
or, during the Transition Period, Sections 9(a) or 9(b) of this Agreement. 

    15.  FULL SETTLEMENT.  The Employer's obligation to make the payments provided
for in this Agreement and otherwise to perform its obligations hereunder shall not be affected by any set-off, counterclaim, recoupment, defense or other claim, right or action which the
Employer may have against the Executive or others. In no event shall the Executive be obligated to seek other employment or take any other action by way of mitigation of the amounts payable to the
Executive under any of the provisions of this Agreement. Unless the Executive's termination of employment gives rise to a right to payments and benefits described in Section 9(f) or, during the
Transition Period, Sections 9(a) or 9(b), if the Executive secures other employment, any benefits the Employer is required to provide to the Executive following termination of the Executive's
employment shall be secondary to those provided by another employer (if any). However, if the Executive's employment is terminated such that the Executive has a right to payments and benefits under
Section 9(f) or, during the Transition Period, Sections 9(a) or 9(b), such amounts shall not be reduced whether or not the Executive obtains other employment. 

    16.  SUCCESSORS; BINDING AGREEMENT.  

    (a) The
Employer will require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business
and/or assets of the Employer, by agreement in form and substance satisfactory to the Executive, to expressly assume and agree to perform this Agreement in the same manner and to the same extent that
the Employer would be required to perform it if no such succession had taken place. Failure of the Employer to obtain such assumption and agreement prior to the effectiveness of any such succession
shall be a breach of the Agreement and shall entitle the Executive to compensation from the Employer in the same amount 

10

 

and on the same terms as he would be entitled to hereunder if he terminated his employment for Good Reason, except that for purposes of implementing the foregoing, the date on which any such
succession becomes effective shall be deemed the date of termination. As used in the Agreement, Employer shall mean the Employer as herein before defined and any successor to its business and/or
assets as aforesaid which executes and delivers the agreement provided for in this Section 16 or which otherwise becomes bound by all the terms and provisions of this Agreement by operation of
law. 

    (b) This
Agreement and all rights of the Executive hereunder shall inure to the benefit of and be enforceable by the Executive's personal or legal representatives,
executors, administrators, successors, heirs, distributees, devises and legatees. If the Executive should die while any amounts would still be payable to him hereunder if he had continued to live, all
such amounts unless otherwise provided herein, shall be paid in accordance with the terms of this Agreement to the Executive's devise, legatee, or other designee or, if there be no such designee, to
the Executive's estate. 

    17.  NOTICE.  For the purposes of this Agreement, notices, demands and all other
communications provided for in this Agreement shall be in writing and shall be deemed to have been duly given when delivered or (unless otherwise specified) mailed by United States certified or
registered mail, return receipt requested, postage prepaid, addressed as follows:

    18.  MISCELLANEOUS.  No provisions 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 such officer of the Employer as may be specifically designated by the Board. 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. No agreements or representations, oral or otherwise, express or implied, with respect to the
subject matter hereof have been made by either party which are not set forth expressly in this Agreement. The validity, interpretation, construction and performance of this Agreement shall be governed
by the laws of New York without regard to its conflicts of law principles. 

    19.  VALIDITY.  The invalidity or unenforceability of any provision or provisions
of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect. 

    20.  COUNTERPARTS.  This Agreement may be executed in one or more counterparts,
each of which shall be deemed to be an original but all of which together will constitute one and the same instrument.

hereto sets forth the entire agreement of the parties hereto in respect of the subject matter contained herein and supersedes all prior agreements, promises, covenants, arrangements, communications, 

11

 

representations or warranties, whether oral or written, by any officer, employee or representative of any party hereto; and any prior agreement of the parties hereto in respect of the subject matter
contained herein is hereby terminated and cancelled, provided, however, that this Agreement should not supersede any existing benefit or agreement which provides such benefit, including, without
limitation, life or disability insurance agreements and retirement plans currently in effect. 

    22.  INDEMNIFICATION.  The Employer hereby covenants and agrees to indemnify the
Executive and hold him harmless to the fullest extent permitted by law and under the By-laws of the Employer against and in respect to any and all actions, suits, proceedings, claims,
demands, judgments, costs, expenses (including reasonable attorneys' fees), losses, and damages resulting from the Executive's good faith performance of his duties and obligations hereunder. The
Employer, within 10 days of presentation of invoices, shall advance to the Executive reimbursement of all legal fees and disbursements incurred by the Executive in connection with any
potentially indemnifiable matter. The Employer will cover the Executive under directors' and officers' liability insurance both during and, while potential liability exists (for such reasonable period
taking into account the applicable statute of limitations but in no event for less than six years), after the Executive's termination of employment in the same amount and to the same extent as the
Employer covers its other officers and directors. 

    23.  WITHHOLDING TAXES.  The Employer may withhold from any and all amounts
payable under this Agreement such Federal, state and local taxes as may be required to be withheld pursuant to any applicable law or regulation. 

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

EXHIBIT A
  
    CHANGE OF CONTROL    
  

    For the purpose of this Agreement, a "Change of Control" shall mean: 

    (a) the
acquisition by any individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act")), other than The Alpine Group, Inc., Steven S. Elbaum or any affiliates thereof (as such term is defined under the Exchange Act) (collectively, "Alpine") (a "Person"), of
beneficial ownership (within the meaning of Rule 13d-3 promulgated under the Exchange Act) of voting securities of the Employer where such acquisition causes such Person to own more
than 20% or more of the combined voting power of the then outstanding voting securities of the Employer entitled to vote generally in the election of directors (the "Outstanding Voting Securities");  provided, however,
 that for purposes of this subsection (a), the following acquisitions shall not be deemed to result in a Change of Control:
(i) any acquisition directly from the Employer, (ii) any acquisition by the Employer, (iii) any acquisition by any employee benefit plan (or related trust) sponsored or maintained
by the Employer or any corporation controlled by the Employer or (iv) any acquisition by any corporation pursuant to a transaction that complies with clauses (i), (ii) and
(iii) of subsection (c) below; and provided, further, that if any Person's beneficial ownership of the Outstanding Voting Securities reaches or exceeds more than 20% as a result of a
transaction described in clause (i) or (ii) above, and such Person subsequently acquires beneficial ownership of additional voting securities of the Employer, such subsequent acquisition
shall be treated as an acquisition that causes such Person to own more than 20% or more of the Outstanding Voting Securities and, further provided,
however, such referenced percentage in this clause (a) shall be 30% if, and so long as, Alpine maintains beneficial ownership of 40% or more on a fully diluted basis of the Employer's capital
stock; or 

    (b) individuals
who, as of the date hereof, constitute the Board (the "Incumbent Board") cease for any reason to constitute at least a majority of the Board; provided,
however, that any individual becoming a director subsequent to the date hereof whose election, or nomination for election by the Employer's shareholders, was approved by a vote of at least a majority
of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose
initial assumption of office occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies
or consents by or on behalf of a Person other than the Board; or 

    (c) the
consummation of a reorganization, merger or consolidation or sale or other disposition of all or substantially all of the assets of the Employer or the
acquisition of assets of another corporation
("Business Combination"); excluding, however, such a Business Combination pursuant to which (i) all or substantially all of the individuals and entities who were the beneficial owners of the
Outstanding Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of, respectively, the then outstanding shares of common stock and
the combined voting power of the then outstanding voting securities entitled to vote generally in the election of directors, as the case may be, of the corporation resulting from such Business
Combination (including, without limitation, a corporation that as a result of such transaction owns the Employer or all or substantially all of the Employer's assets either directly or through one or
more subsidiaries) in substantially the same proportions as their ownership, immediately prior to such Business Combination of the Outstanding Voting Securities, (ii) no Person (excluding
Alpine or any employee benefit plan (or related trust) of the Employer or such corporation resulting from such Business Combination) beneficially owns, directly or indirectly, more than 20% or more
of, respectively, the then outstanding shares of common stock of the corporation resulting from such Business Combination or the combined voting power of the then outstanding voting securities of such
Business Combination except to the 

A–1

 

extent that such Person owned 20% or more of the Outstanding Voting Securities prior to the Business Combination and (iii) at least a majority of the members of the board of directors of the
corporation resulting from such Business Combination were members of the Incumbent Board at the time of the execution of the initial agreement, or of the action of the Board, providing for such
Business Combination; or 

    (d) approval
by the shareholders of the Employer of a complete liquidation or dissolution of the Employer. 

A–2

  

 
 

EXHIBIT B
  
    GOLDEN PARACHUTE PROVISIONS    
  

    (a) Anything
in this Agreement to the contrary notwithstanding and except as set forth below, in the event it shall be determined that any payment or distribution by
the Employer to or for the benefit of the Executive (whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, but determined without regard to any
additional payments required under this Exhibit B) (a "Payment") would be subject to the excise tax imposed by Section 4999 of the Code or any interest or penalties are incurred by the
Executive with respect to such excise tax (such excise tax, together with any such interest and penalties, are hereinafter collectively referred to as the "Excise Tax"), then the Executive shall be
entitled to receive an additional payment (a "Gross-Up Payment") in an amount such that after payment by the Executive of all taxes (including any interest or penalties imposed with
respect to such taxes), including, without limitation, any income taxes (and any interest and penalties imposed with respect thereto) and Excise Tax imposed upon the Gross-Up Payment, the
Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payments. Notwithstanding the foregoing, if it shall be determined that the Executive is
entitled to a Gross-Up Payment, but that the Payments do not exceed 110% of the greatest amount (the "Reduced Amount") that could be paid to the Executive such that the receipt of Payments
would not give rise to any Excise Tax, then no Gross-Up Payment shall be made to the Executive and the Payments, in the aggregate, shall be reduced to the Reduced Amount. 

    (b) Subject
to the provisions of paragraph (c), all determinations required to be made under this Exhibit B, including whether and when a
Gross-Up Payment is required and the amount of such Gross-Up Payment and the assumptions to be utilized in arriving at such determination, shall be made by Arthur Andersen LLP
or such other certified public accounting firm as may be designated by the Executive (the "Accounting Firm") which shall provide detailed supporting calculations both to the Parent and the Executive
within 15 business days of the receipt of notice from the Executive that there has been a Payment, or such earlier time as is requested by the Parent. In the event that the Accounting Firm is serving
as accountant or auditor for the individual, entity or group effecting the Change of Control or other change of ownership as defined under Section 280G of the Code, the Executive shall appoint
another nationally recognized accounting firm to make the determinations required hereunder (which accounting firm shall then be referred to as the Accounting Firm hereunder). All fees and expenses of
the Accounting Firm shall be borne solely by the Parent. Any Gross-Up Payment, as determined pursuant to this Exhibit B, shall be paid by the Parent to the Executive within five
days of the receipt of the Accounting Firm's determination. Any determination by the Accounting Firm shall be binding upon the Employer and the Executive. As a result of the uncertainty in the
application of Section 4999 of the Code at the time of the initial determination by the Accounting Firm hereunder, it is possible that Gross-Up Payments which will not have been
made by the Parent should have been made ("Underpayment"), consistent with the calculations required to be
made hereunder. In the event that the Parent exhausts its remedies pursuant to paragraph (c) and the Executive thereafter is required to make a payment of any Excise Tax, the Accounting Firm
shall determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Parent to or for the benefit of the Executive. 

    (c) The
Executive shall notify the Parent in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Parent of the
Gross-Up Payment. Such notification shall be given as soon as practicable but no later than 10 business days after the Executive is informed in writing of such claim and shall apprise the
Parent of the nature of such claim and the date on which such claim is requested to be paid. The Executive shall not pay such claim prior to the expiration of the 30-day period following
the date on which it gives such notice to the Parent (or such shorter period ending on the date that any payment of taxes with respect to such claim is due). If the Parent notifies 

B–1

 

the Executive in writing prior to the expiration of such period that it desires to contest such claim, the Executive shall: 

    (i)  give
the Parent any information reasonably requested by the Parent relating to such claim, 

    (ii) take
such action in connection with contesting such claim as the Parent shall reasonably request in writing from time to time, including, without limitation,
accepting legal representation with respect to such claim by an attorney reasonably selected by the Parent, 

    (iii) cooperate
with the Parent in good faith in order effectively to contest such claim, and 

    (iv) permit
the Parent to participate in any proceedings relating to such claim; 

provided,
however, that the Parent shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and
hold the Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and
payment of costs and expenses. Without limitation on the foregoing provisions of this paragraph (c), the Parent shall control all proceedings taken in connection with such contest and, at its
sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct
the Executive to pay the tax claimed and sue for a refund or contest the claim in any permissible manner, and the Executive agrees to prosecute such contest to a determination before any
administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Parent shall determine; provided, however, that if the Parent
directs the Executive to pay such claim and sue for a refund, the Parent shall advance the amount of such payment to the Executive, on an interest-free basis and shall indemnify and hold
the Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect
to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations relating to payment of taxes for the taxable year of the Executive with
respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Parent's control of the contest shall be limited to issues with respect to
which a Gross-Up Payment would be payable hereunder and the Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or
any other taxing authority. 

    (d) If,
after the receipt by the Executive of an amount advanced by the Parent pursuant to paragraph (c), the Executive becomes entitled to receive any refund
with respect to such claim, the Executive shall (subject to the Parent's complying with the requirements of paragraph (c)) promptly pay to the Parent the amount of such refund (together with
any interest paid or credited thereon after taxes applicable thereto). If, after the receipt by the Executive of an amount advanced by the Parent pursuant to paragraph (c), a determination is
made that the Executive shall not be entitled to any refund with respect to such claim and the Parent does not notify the Executive in writing of its intent to contest such denial of refund prior to
the expiration of 30 days after such determination, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent
thereof, the amount of Gross-Up Payment required to be paid.
