                           NATIONAL DENTEX CORPORATION

                          1992 LONG TERM INCENTIVE PLAN

              Adopted by the Board of Directors as of May 22, 1992

SECTION 1.        Purpose.

         The purpose of National Dentex Corporation's 1992 Long Term Incentive
Plan (the "LTIP") is to promote the interests of National Dentex Corporation
(the "Company") and its Subsidiaries, Affiliates and stockholders by enabling
the Company to attract, retain and reward employees, officers and directors of
the Company and its Subsidiaries and Affiliates, and strengthening the mutuality
of interests between such employees, officers and directors and the Company's
stockholders, by offering such employees, officers and directors
performance-based stock incentives and/or other equity interests or equity-based
incentives in the Company, as well as performance-based incentives payable in
cash.

         Certain terms used herein are defined in Section 17 of the LTIP.

SECTION 2.        Stock Subject to the LTIP.

         The maximum aggregate number of shares of Stock reserved and available
for distribution under the LTIP shall be 150,000 shares of Stock. Such shares
may consist, in whole or in part, of authorized and unissued shares or treasury
shares.

         Subject to Section 6(b)(iv) below, if any shares of Stock that have
been optioned under the LTIP cease to be subject to a Stock Option, or if any
such shares of Stock that are subject to any Restricted Stock or Deferred Stock
award, Stock Purchase Right or Other Stock-Based Award granted hereunder are
forfeited or any such Award otherwise terminates, without a payment being made
to the participant in the form of Stock, such shares shall be available for
distribution in connection with future awards under the LTIP. Notwithstanding
any other provision of the LTIP, shares issued under the LTIP and later
repurchased by the Company shall not become available for future distribution
under the LTIP.

         In the event of any recapitalization, Stock dividend, Stock split,
reclassification or other change in corporate structure affecting the Stock,
such substitution or adjustment shall be made in the aggregate number of shares
reserved for issuance under the LTIP, in the number and option price of shares
subject to outstanding Options granted under the LTIP, in the number and
purchase price of shares subject to outstanding Stock Purchase Rights under the
LTIP, and in the number of shares subject to other outstanding Awards granted
under the LTIP as may be determined to be appropriate by the Board, in its sole
discretion, provided that the number of shares subject to any Award shall always
be a whole number. Such adjusted option price shall also be used to determine
the amount payable by the Company upon the exercise of any Stock Appreciation
Right associated with any Stock Option.

         In the event of a merger or consolidation of the Company with another
corporation such that the Company is not the surviving entity, the Board may
decide in its discretion: (i) to terminate all the outstanding Stock Options
issued hereunder, and to provide that all Deferred Stock and Restricted Stock
which is subject to forfeiture or which has not been received shall be forfeited
or not received, or (ii) arrange to have the merged or consolidated corporation
assume such Stock Options, Deferred Stock or Restricted Stock or issue
substitute Stock Options, Deferred Stock or Restricted Stock therefor. In the
event the merged or consolidated corporation does not assume such Stock Options,
Deferred Stock or Restricted Stock or issue substitute Stock Options, Deferred
Stock or Restricted Stock therefor, or such Stock Options, Deferred Stock or
Restricted Stock are terminated or forfeited, as the case may be, the Board in
its

<PAGE>

discretion may provide that (i) each optionee shall have the right, immediately
prior thereto, to exercise his Stock Option(s) in whole or in part without
regard to any installment restrictions as to time of exercise otherwise imposed
under the LTIP, and (ii) each holder of Deferred Stock or Restricted Stock shall
have the right, immediately prior thereto, to receive and own all such stock
without regard to any restrictions otherwise imposed under the LTIP.

SECTION 3.        Eligibility.

         Employees, officers and directors of the Company and its Subsidiaries
and Affiliates who are responsible for or contribute to the management, growth
and/or profitability of the business of the Company and/or its Subsidiaries and
Affiliates are eligible to be granted Awards under the LTIP; provided, however,
that only Employees of the Company and its Subsidiaries are eligible to be
granted Incentive Stock Options under the LTIP.

SECTION 4.        Administration.

         a.       General Administration. The LTIP shall be administered by the
Board, which shall have full authority to grant Awards, pursuant to the terms of
the LTIP, to Employees eligible under Section 3.

         In particular, the Board shall have the authority:

                  (i)      to select the Employees of the Company and its
         Subsidiaries and Affiliates to whom Awards may from time to time be
         granted hereunder;

                  (ii)     to determine whether and to what extent Awards are to
         be granted hereunder to one or more eligible Employees;

                  (iii)    to determine the number of shares to be covered by
         each such Award granted hereunder;

                  (iv)     to determine the terms and conditions, not
         inconsistent with the terms of the LTIP, of any Award granted hereunder
         (including, but not limited to, the share price and any restriction or
         limitation, or any vesting, acceleration or waiver of forfeiture
         restrictions regarding any Stock Option or other Award and/or Deferred
         Stock under Sections 5(k) or (1), as applicable, instead of Stock);

                  (v)      to determine whether and under what circumstances a
         Stock Option may be settled in Stock, Restricted Stock and/or Deferred
         Stock under Sections 5(k) or (1), as applicable, instead of cash;

                  (vi)     to determine whether, to what extent and under what
         circumstances grants and/or other Awards under the LTIP and/or other
         cash awards made by the Company are to be made, and operate, on a
         tandem basis vis-a-vis other Awards under the LTIP and/or cash awards
         made outside of the LTIP, or on an additive basis;

                  (vii)    to determine whether, to what extent and under what
         circumstances Stock and other amounts payable with respect to an Award
         under the LTIP shall be deferred either automatically or at the
         election of the participant (including providing for and determining
         the amount (if any) of any deemed earnings on any deferred amount
         during any deferral period); and

                  (viii)   to determine the terms and restrictions applicable to
         Stock Purchase Rights and the Stock purchased by exercising such Stock
         Purchase Rights.

<PAGE>

         The Board shall have the authority to adopt, alter and repeal such
rules, guidelines and practices governing the LTIP as it shall, from time to
time, deem advisable; to interpret the terms and provisions of the LTIP and any
Award issued under the LTIP (and any agreements relating thereto); and to
otherwise supervise the administration of the LTIP.

         All decisions made by the Board pursuant to the provisions of the LTIP
shall be made in the Board's sole discretion and shall be final and binding on
all persons, including the Company and LTIP participants.

         b.       Compliance with Rule 16b-3. It is the intention of the Company
that the LTIP comply with Rule 16b-3 and therefore, notwithstanding the
foregoing, Awards to persons subject to Section 16 shall be made by a Committee
of not less than two (2) Disinterested Persons (none of whom have received an
Award under the LTIP during the one-year period prior to service on such
Committee, or during such service, any grant of equity securities of the Company
pursuant to the LTIP or any other plan of the Company) who shall be appointed by
the Board and who shall serve at the pleasure of the Board. The Committee shall
have the same authority with respect to Awards as the Board under the Plan,
except that such authority is limited in the following respects:

                  (i)      the price per share of any Stock, Stock Option, Stock
         Appreciation Right, Restricted Stock, Deferred Stock, Stock Purchase
         Right, Other Stock-Based Award or any other derivative security (as
         defined in Rule 16a-1(c) of Section 16) awarded under the LTIP shall
         never be less than the par value of the Stock; and

                  (ii)     any Stock granted must be held for six (6) months
         from the date of grant, or, if a derivative security has been granted
         under the LTIP, at least six (6) months must elapse from the date of
         acquisition of the derivative security to the date of disposition of
         the derivative security (other than upon exercise or conversion) or the
         underlying Stock.

         To the extent any provision of the Plan or action by the Board fails to
comply with Rule 16b-3, it shall be deemed null and void.

SECTION 5.        Stock Options.

         Stock Options may be granted alone, in addition to or in tandem with
other Awards granted under the LTIP and/or cash awards made outside of the LTIP.
Each Stock Option granted under the LTIP shall be in such form as the Board may
from time to time approve.

         Stock Options granted under the LTIP may be of two types: (i) Incentive
Stock Options, and (ii) Non-Qualified Stock Options.

         The Board shall have the authority to grant to any optionee Incentive
Stock Options, Non-Qualified Stock Options, or both types of Stock Options (in
each case with or without Stock Appreciation Rights).

         Options granted under the LTIP shall be subject to the following terms
and conditions and shall contain such additional terms and conditions, not
inconsistent with the terms of the LTIP, as the Board shall deem desirable:

         a.       Option Price. The option price per share of Stock purchasable
under a Stock Option shall be determined by the Board at the time of grant and
may be equal to, greater than or less than one hundred percent (100%) of the
Fair Market Value of the Stock at the date of grant; provided, however, that the
option price per share of Stock purchasable under an Incentive Stock Option
shall not be less than one hundred percent (100%) of the Fair Market Value of
the Stock at the date of grant; and provided further however, that in the case
of an Incentive Stock Option granted to an Employee who, at the time of grant,
owns Stock possessing more than ten percent (10%) of the total combined voting
power of all classes of Stock of the Company, its Subsidiaries or Affiliates,
the option price per share

<PAGE>

of Stock shall not be less than one hundred ten percent (110%) of the Fair
Market Value of the Stock at the date of grant.

         b.       Option Term. The term of each Stock Option shall be fixed by
the Board, but no Stock Option shall be exercisable more than ten (10) years
after the date the Option is granted.

         c.       Exercisability. Stock Options shall be exercisable at such
time or times and subject to such terms and conditions as shall be determined by
the Board at or after grant; provided, however, that, except as provided in
Sections 2, 5(f) and 5(g), unless and otherwise determined by the Board at or
after grant, no Stock Option shall be exercisable prior to the first anniversary
of the granting of the Option. If the Board provides, in its sole discretion,
that any Stock Option is exercisable only in installments, the Board may waive
such installment exercise provisions at any time at or after grant in whole or
in part, based on such factors as the Board shall determine in its sole
discretion.

         d.       Method of Exercise. Subject to whatever installment exercise
provisions apply under Section 5(c), Stock Options may be exercised in whole or
in part at any time during the option period, by giving written notice of
exercise to the Company specifying the number of shares to be purchased.

         Such notice shall be accompanied by payment in full of the purchase
price, either by check, note or such other instrument as the Board may accept.
As determined by the Board, in its sole discretion, at or after grant, payment
in full or in part may also be made in the form of unrestricted Stock already
owned by the optionee or, in the case of the exercise of a Non-Qualified Stock
Option, payment in full or in part may be made in the form of Restricted Stock
or Deferred Stock subject to an Award hereunder (based, in each case, on the
Fair Market Value of the Stock on the date the option is exercised, as
determined by the Board).

         If payment of the option exercise price of a Non-Qualified Stock Option
is made in whole or in part in the form of Restricted Stock or Deferred Stock,
such Restricted Stock or Deferred Stock (and any replacement shares relating
thereto) shall remain (or be) restricted or deferred, as the case may be, in
accordance with the original terms of the Restricted Stock award or Deferred
Stock award in question, and any additional Stock received upon the exercise
shall be subject to the same forfeiture restrictions or deferral limitations,
unless otherwise determined by the Board, in its sole discretion, at or after
grant.

         No shares of Stock shall be issued until full payment therefor has been
made. Until the issuance (as evidenced by the appropriate entry on the books of
the Company or of a duly authorized transfer agent of the Company) of the stock
certificate evidencing such Stock, and compliance with the applicable
requirements, if any, of Section 14(a), no right to vote or receive dividends or
any other rights as a stockholder shall exist with respect to such Stock Option.

         e.       Non-Transferability of Options. No Stock Option shall be
transferable by the optionee otherwise than by will or by the laws of descent
and distribution or pursuant to a qualified domestic relations order, as defined
by the Code, or Title I of the Employee Retirement Income Security Act, or the
rules thereunder, and all Stock Options shall be exercisable, during the
optionee's lifetime, only by the Optionee.

         f.       Termination by Death. Subject to Section 5(j), if an
optionee's employment by the Company and any Subsidiary or Affiliate terminates
by reason of death, any Stock Option held by such optionee may thereafter be
exercised, to the extent such option was exercisable at the time of death or on
such accelerated basis as the Board may determine at or after grant (or as may
be determined in accordance with procedures established by the Board), by the
legal representative of the estate or by the legatee of the optionees under the
will of the optionee, for a period of one year (or such other period as the
Board may specify at grant) from the date of such death or until the expiration
of the stated term of such Stock Option, whichever period is the shorter.

         g.       Termination by Reason of Disability. Subject to Section 5(j),
if an optionee's employment by the Company and any Subsidiary or Affiliate
terminates by reason of Disability, any Stock Option held by such optionee may
thereafter be exercised by the optionee, to the extent it was exercisable at the
time of termination or on such

<PAGE>

accelerated basis as the Board may determine at or after grant (or as may be
determined in accordance with procedures established by the Board), for a period
of ninety (90) days (or such other period as the Board may specify at grant)
from the date of such termination of employment or until the expiration of the
stated term of such Stock Option, whichever period is the shorter; provided,
however, that, if the optionee dies within such ninety (90) day period (or such
other period as the Board shall specify at grant), any unexercised Stock Option
held by such optionee shall thereafter be exercisable to the extent to which it
was exercisable at the time of death for a period of twelve (12) months, from
the date of such death or until the expiration of the stated term of such Stock
Option, whichever period is the shorter. In the event of termination of
employment by reason of Disability, if an Incentive Stock Option is exercisable
after the expiration of the exercise periods that apply for purposes of Section
422 of the Code, such Stock Option will thereafter be treated as a Non-Qualified
Stock Option.

         h.       Termination by Reason of Retirement. Subject to Section 5(j),
if an optionee's employment by the Company and any Subsidiary or Affiliate
terminates by reason of Normal or Early Retirement, any Stock Option held by
such optionee may thereafter be exercised by the optionee, to the extent it was
exercisable at the time of such Retirement or on such accelerated basis as the
Board may determine at or after grant (or as may be determined in accordance
with procedures established by the Board), for a period of ninety (90) days (or
such other period as the Board may specify at grant) from the date of such
termination of employment or the expiration of the stated term of such Stock
Option, whichever period is the shorter; provided, however, that, if the
optionee dies within such ninety (90) day period (or such other period as the
Board may specify at grant), any unexercised Stock Option held by such optionee
shall thereafter be exercisable, to the extent to which it was exercisable at
the time of death, for a period of twelve (12) months from the date of such
death or until the expiration of the stated term of such Stock Option, whichever
period is the shorter. In the event of termination of employment by reason of
Retirement, if an Incentive Stock Option is exercised after the expiration of
the exercise periods that apply for purposes of Section 422 of the Code, such
Stock Option will thereafter be treated as a Non-Qualified Stock Option.

         i.       Other Termination. Unless otherwise determined by the Board
(or pursuant to procedures established by the Board) at or after grant, if an
optionee's employment by the Company and any Subsidiary or Affiliate terminates
for any reason other than death, Disability or Normal or Early Retirement, the
Stock Option shall thereupon terminate, except that such Stock Option may be
exercised, to the extent otherwise then exercisable, for the lesser of three (3)
months or the balance of such Stock Option's term if the optionee is
involuntarily terminated without Cause by the Company and any Subsidiary or
Affiliate. For purposes of the LTIP, "Cause" means a felony conviction of a
participant or the failure of a participant to contest prosecution for a felony,
or a participant's willful misconduct or dishonesty, any of which is directly
and materially harmful to the business or reputation of the Company or any
Subsidiary or Affiliate.

         j.       Incentive Stock Options. Anything in the LTIP to the contrary
notwithstanding, no term of this LTIP relating to Incentive Stock Options shall
be interpreted, amended or altered, nor shall any discretion or authority
granted under the LTIP be so exercised, so as to disqualify the LTIP under
Section 422 of the Code, or, without the consent of the optionee(s) affected, to
disqualify any Incentive Stock Option under such Section 422.

         Incentive Stock Options shall not be treated as "incentive stock
options" to the extent that the aggregate Fair Market Value (determined at the
time an Incentive Stock Option is granted) of Stock with respect to which
Incentive Stock Options meeting the requirements of Section 422(b) of the Code
are exercisable for the first time by any participant during any calendar year
(under all plans of the Company and its Subsidiaries) exceeds $100,000, and such
excess shall be treated as a Non-Qualified Stock Option.

         To the extent permitted under Section 422 of the Code or the applicable
regulations thereunder or any applicable Internal Revenue Service pronouncement:

                  (i)      if (x) a participant's employment is terminated by
         reason of death, Disability or Normal or Early Retirement, and (y) the
         portion of any Incentive Stock Option exercisable during the
         post-termination period specified under Sections 5(f), (g) or (h) is
         greater than the portion of such option that is immediately

<PAGE>

         exercisable as an "incentive stock option" during such post-termination
         period under Section 422, such excess shall be treated as a
         Non-Qualified Stock Option; and

                  (ii)     if the exercise of an Incentive Stock Option is
         accelerated by reason of a merger or consolidation of the Company with
         another company whereby the Company is not the surviving corporation,
         any portion of such option that is not exercisable as an Incentive
         Stock Option by reason of the $100,000 limitation contained in Section
         422(d) of the Code shall be treated as a Non-Qualified Stock Option.

         k.       Buyout Provisions. The Board may at any time offer to purchase
an Option previously granted for a payment in cash, Stock, Deferred Stock or
Restricted Stock, based on such terms and conditions as the Board shall
establish and communicate to the optionee at the time that such offer is made.

         l.       Settlement Provisions. If the option agreement so provides at
grant or is amended after grant and prior to exercise to so provide (with the
optionee's consent), the Board may require that all or part of the shares to be
issued with respect to an exercised Option take the form of Deferred or
Restricted Stock, which shall be valued on the date of exercise on the basis of
the Fair Market Value (as determined by the Board) of such Deferred or
Restricted Stock determined without regard to the deferral limitations and/or
forfeiture restrictions involved.

SECTION 6.        Stock Appreciation Rights.

         a.       Grant and Exercise. Stock Appreciation Rights may be granted
in conjunction with all or part of any Stock Option granted under the LTIP. In
the case of a Non-Qualified Stock Option, such rights may be granted either at
or after the time of the grant of such Stock Option. In the case of an Incentive
Stock Option, such rights may be granted only at the time of the grant of such
Stock Option.

         A Stock Appreciation Right or applicable portion thereof granted with
respect to a given Stock Option shall terminate and no longer be exercisable
upon the termination or exercise of the related Stock Option, subject to such
provisions as the Board may specify at grant where a Stock Appreciation Right is
granted with respect to less than the full number of shares covered by a related
Stock Option.

         A Stock Appreciation Right may be exercised by an optionee, subject to
Section 6(b), in accordance with the procedures established by the Board for
such purpose. Upon such exercise, the optionee shall be entitled to receive an
amount determined in the manner prescribed in Section 6(b). Stock Options
relating to exercised Stock Appreciation Rights shall no longer be exercisable
to the extent that the related Stock Appreciation Rights have been exercised.

         b.       Terms and Conditions. Stock Appreciation Rights shall be
subject to such terms and conditions, not inconsistent with the provisions of
the LTIP, as shall be determined from time to time by the Board, including the
following:

                  (i)      Stock Appreciation Rights shall be exercisable only
         at such time or times and to the extent that Stock Options to which
         they relate shall be exercisable in accordance with the provisions of
         Section 5 and this Section 6 of the LTIP;

                  (ii)     Upon the exercise of a Stock Appreciation Right, an
         optionee shall be entitled to receive an amount in cash and/or shares
         of Stock equal in value to the excess of the Fair Market Value of one
         share of Stock over the option price per share specified in the related
         Stock Option multiplied by the number of shares in respect of which the
         Stock Appreciation Right shall have been exercised, with the Board
         having the right to determine the form of payment. When payment is to
         be made in shares of Stock, the number of shares to be paid shall be
         calculated on the basis of the average of the highest and lowest quoted
         selling price, regular way, of the Stock on the National Association of
         Securities Dealers Automated Quotation System during the applicable
         period referred to in Rule 16b-3(e) promulgated under the Exchange Act.

<PAGE>

                  (iii)    Stock Appreciation Rights shall be transferable only
         when and to the extent that the underlying Stock Option would be
         transferable under Section 5(e) of the LTIP.

                  (iv)     Upon the exercise of a Stock Appreciation Right, the
         Stock Option or part thereof to which such Stock Appreciation Right is
         related shall be deemed to have been exercised for the purpose of the
         limitation set forth in Section 3 of the LTIP on the number of shares
         of Stock to be issued under the LTIP, but only to the extent of the
         number of shares issued under the Stock Appreciation Right at the time
         of exercise based on the value of the Stock Appreciation Right at such
         time.

SECTION 7.        Restricted Stock.

         a.       Administration. Shares of Restricted Stock may be issued
either alone, in addition to or in tandem with other Awards granted under the
LTIP and/or cash awards made outside the LTIP. The Board shall determine the
eligible persons to whom, and the time or times at which, awards of Restricted
Stock will be made, the number of shares to be awarded, the price (if any) to be
paid by the recipient of Restricted Stock (subject to Section 7(b)), the time or
times within with such awards may be subject to forfeiture, and all other terms
and conditions of the awards of Restricted Stock.

         The Board may condition an award of Restricted Stock upon the
attainment of specified performance goals or such other factors as the Board may
determine, in its sole discretion.

         The provisions of Restricted Stock awards need not be the same with
respect to each recipient.

         b.       Awards and Certificates. The prospective recipient of a
Restricted Stock award shall not have any rights with respect to such award,
unless and until such recipient has executed an agreement evidencing the award
and has delivered a fully executed copy thereof to the Company, and has
otherwise complied with the applicable terms and conditions of such award.

                  (i)      The purchase price for shares of Restricted Stock
         shall be equal to, less than or greater than their par value and may be
         zero.

                  (ii)     Awards of Restricted Stock must be accepted within a
         period of sixty (60) days (or such shorter period as the Board may
         specify at grant) after the award date, by executing a Restricted Stock
         award agreement and paying whatever price (if any) is required under
         Section 7(b)(i).

                  (iii)    Each participant receiving a Restricted Stock award
         shall be issued a stock certificate in respect of such shares of
         Restricted Stock. Such certificate shall be registered in the name of
         such participant, and shall bear an appropriate legend referring to the
         terms, conditions, and restrictions applicable to such award.

                  (iv)     The Board shall require that the stock certificates
         evidencing such shares be held in custody by the Company until the
         restrictions thereon shall have lapsed, and that, as a condition of any
         Restricted Stock award, the participant shall have delivered a stock
         power, endorsed in blank, relating to the Stock covered by such award.

         c.       Restrictions and Conditions. The shares of Restricted Stock
awarded pursuant to this Section 7 shall be subject to the following
restrictions and conditions:

                  (i)      Subject to the provisions of the LTIP and the award
         agreement, during a period set by the Board commencing with the date of
         such award (the "Restricted Period"), the participant shall not be

         permitted to sell, transfer, pledge or assign shares of Restricted
         Stock awarded under the LTIP. Within these limits, the Board, in its
         sole discretion, may provide for the lapse of such restrictions in
         installments and may accelerate or waive such restriction in whole or
         in part, based on service, performance and/or such other factors or
         criteria as the Board may determine, in its sole discretion.

                  (ii)     Except as provided in this paragraph (ii) and Section
         7(c)(i), the participant shall have, with respect to the shares of
         Restricted Stock, all of the rights of a stockholder of the Company,
         including the right to vote the shares, and the right to receive any
         cash dividends. The Board, in its sole discretion, as determined at the
         time of award, may permit or require the payment of cash dividends to
         be deferred and, if the Board so determines, reinvested, subject to
         Section 14(e), in additional Restricted Stock to the extent shares are
         available under Section 3, or otherwise reinvested. Pursuant to Section
         3 above, Stock dividends issued with respect to Restricted Stock shall
         be treated as additional shares of Restricted Stock that are subject to
         the same restrictions and other terms and conditions that apply to the
         shares with respect to which such dividends are issued.

                  (iii)    Subject to the applicable provisions of the award
         agreement and this Section 7, upon termination of a participant's
         employment with the Company and any Subsidiary or Affiliate for any
         reason during the Restriction Period, all shares still subject to
         restriction will vest, or be forfeited, in accordance with the terms
         and conditions established by the Board at or after grant.

                  (iv)     If and when the Restriction Period expires without a
         prior forfeiture of the Restricted Stock subject to such Restriction
         Period, certificates for an appropriate number of unrestricted shares
         shall be delivered to the participant promptly.

         d.       Minimum Value Provision. In order to better ensure that Award
payments actually reflect the performance of the Company and service of the
participant, the Board may provide, in its sole discretion, for a tandem
performance-based or other Award designed to guarantee a minimum value, payable
in cash or Stock to the recipient of a Restricted Stock award, subject to such
performance, future service deferral and other terms and conditions as may be
specified by the Board.

SECTION 8.        Deferred Stock.

         a.       Administration. Deferred Stock may be awarded either alone, in
addition to or in tandem with other Awards granted under the LTIP and/or cash
awards made outside the LTIP. The Board shall determine the eligible persons to
whom and the time or times at which Deferred Stock shall be awarded, the number
of shares of Deferred Stock to be awarded to any person, the duration of the
period (the "Deferral Period") during which, and the conditions under which,
receipt of the Stock will be deferred, and the other terms and conditions of the
award in addition to those set forth in Section 8(b).

         The Board may condition the grant of Deferred Stock upon the attainment
of specified performance goals or such other factors or criteria as the Board
shall determine, in its sole discretion.

         The provisions of Deferred Stock awards need not be the same with
respect to each recipient.

         b.       Terms and Conditions. The shares of Deferred Stock awarded
pursuant to this Section 8 shall be subject to the following terms and
conditions:

                  (i)      Subject to the provisions of the LTIP and the award
         agreement referred to in Section 8(b)(vi) below, Deferred Stock awards
         may not be sold, assigned, transferred, pledged or otherwise encumbered
         during the Deferral Period. At the expiration of the Deferral Period
         (or the Elective Deferral

<PAGE>

         Period referred to in Section 8(b)(v), where applicable), share
         certificates shall be delivered to the participant, or his legal
         representative, in a number equal to the shares covered by the Deferred
         Stock award.

                  (ii)     Unless otherwise determined by the Board at grant,
         amounts equal to any dividends declared during the Deferral Period with
         respect to the number of shares covered by a Deferred Stock award will
         be paid to the participant currently, or deferred and deemed to be
         reinvested in additional Deferred Stock, or otherwise reinvested, all
         as determined at or after the time of the award by the Board, in its
         sole discretion.

                  (iii)    Subject to the provision of the award agreement and
         this Section 8, upon termination of a participant's employment with the
         Company and any Subsidiary or Affiliate for any reason during the
         Deferral Period for a given award, the Deferred Stock in question will
         vest, or be forfeited, in accordance with the terms and conditions
         established by the Board at or after grant.

                  (iv)     Based on service, performance and/or such other
         factors or criteria as the Board may determine, the Board may, at or
         after grant, accelerate the vesting of all or any part of any Deferred
         Stock award and/or waive the deferral limitations for all or any part
         of such award.

                  (v)      A participant may elect to further defer receipt of
         an award (or an installment of an award) for a specified period or
         until a specified event (the "Elective Deferral Period"), subject in
         each case to the Board's approval and to such terms as are determined
         by the Board, all in its sole discretion. Subject to any exceptions
         adopted by the Board, such election must generally be made at least
         twelve (12) months prior to completion of the Deferral Period for such
         Deferred Stock award (or such installment).

                  (vi) Each award shall be confirmed by, and subject to the
         terms of, a Deferred Stock agreement executed by the Company and the
         participant.

         c.       Minimum Value Provisions. In order to better ensure that Award
                  payments actually reflect the performance of the Company and
                  service of the participant, the Board may provide, in its sole
                  discretion, for a tandem performance-based or other Award
                  designed to guarantee a minimum value, payable in cash or
                  Stock to the recipient of a Deferred Stock award, subject to
                  such performance, future service, deferral and other terms and
                  conditions as may be specified by the Board.

                           SECTION 9.        Stock Purchase Rights.

         a.       Awards and Administration. Subject to Section 3 above, the
Board may grant eligible participants Stock Purchase Rights which shall enable
such participants to purchase Stock (including Deferred Stock and Restricted
Stock):

                  (i)      at its Fair Market Value on the date of grant;

                  (ii)     at fifty percent (50%) of such Fair Market Value on
         such date;

                  (iii)    at an amount equal to Book Value on such date; or

                  (iv)     at an amount equal to the par value of such Stock on
         such date.

         The Board shall also impose such deferral, forfeiture and/or other
terms and conditions as it shall determine, in its sole discretion, on such
Stock Purchase Rights or the exercise thereof.

         The terms of Stock Purchase Rights awards need not be the same with
respect to each participant.

<PAGE>

         Each Stock Purchase Right award shall be confirmed by, and be subject
to the terms of, a Stock Purchase Rights Agreement.

         b.       Exercisability. Stock Purchase Rights shall generally be
exercisable for such period after grant as is determined by the Board, not to
exceed thirty (30) days.

SECTION 10.       Other Stock-Based Awards.

         a.       Administration. Other awards of Stock and other Awards that
are valued in whole or in part by reference to, or are otherwise based on, Stock
("Other Stock-Based Awards"), including, without limitation, performance shares,
convertible preferred stock, convertible debentures, exchangeable securities and
Stock awards or options valued by reference to Book Value or Subsidiary
performance, may be granted alone, in addition to or in tandem with Awards
granted under the LTIP and/or cash awards made outside of the LTIP.

         Subject to the provisions of the LTIP, the Board shall have authority
to determine the persons to whom and the time or times at which such Other
Stock-Based Awards shall be made, the number of shares of Stock to be awarded
pursuant to such Other Stock-Based Awards, and all other conditions of the Other
Stock-Based Awards. The Board shall also provide for the grant of Stock upon the
completion of a specified performance period.

         The provisions of Other Stock-Based Awards need not be the same with
respect to each recipient.

         b.       Terms and Conditions. Other Stock-Based Awards made pursuant
to this Section 10 shall be subject to the following terms and conditions:

                  (i)      Subject to the provisions of this LTIP and the award
         agreement referred to in Section 10(b)(v) below, shares subject to
         Other Stock-Based Awards made under this Section 10 may not be sold,
         assigned, transferred, pledged or otherwise encumbered prior to the
         date on which the shares are issued, or, if later, the date on which
         any applicable restriction, performance or deferral period lapses.

<PAGE>

                  (ii)     Subject to the provisions of the LTIP and the award
         agreement and unless otherwise determined by the Board at grant, the
         recipient of an Other Stock-Based Award under this Section 10 shall be
         entitled to receive, currently or on a deferred basis, interest or
         dividends or interest or dividend equivalents with respect to the
         number of shares covered by such Other Stock-Based Award, as determined
         at the time of the Other Stock-Based Award by the Board, in its sole
         discretion, and the Board may provide that such amounts (if any) shall
         be deemed to have been reinvested in additional Stock or otherwise
         reinvested.

                  (iii)    Any Other Stock-Based Award under Section 10 and any
         Stock covered by any such Other Stock-Based Award shall vest or be
         forfeited to the extent so provided in the award agreements, as
         determined by the Board, in its sole discretion.

                  (iv)     In the event of the participant's Retirement,
         Disability or death, or in cases of special circumstances, the Board
         may, in its sole discretion, waive in whole or in part any or all of
         the remaining limitations imposed hereunder (if any) with respect to
         any or all of an Other Stock-Based Award under this Section 10.

                  (v)      Each Other Stock-Based Award under this Section 10
         shall be confirmed by, and subject to the terms of, an agreement or
         other instrument by the Company and by the participant.

                  (vi)     Stock (including securities convertible into Stock)
         issued on a bonus basis under this Section 10 may be issued for no cash
         consideration. Stock (including securities convertible into Stock)
         purchased pursuant to a purchase right awarded under this Section 10
         shall be priced at least fifty percent (50%) of the Fair Market Value
         of the Stock on the date of grant.

SECTION 11.       Change in Control Provisions.

         a.       Impact of Event. In the event of:

         (1)      a Change in Control; or

         (2)      a Potential Change in Control, but only if and to the extent
so determined by the Board or the Board at or after grant (subject to any right
of approval expressly reserved by the Board or the Board at the time of such
determination);

the following acceleration and valuation provisions shall apply:

                  (i)      Any Stock Appreciation Rights (including, without
         limitation, any Limited Appreciation Rights) outstanding for at least
         six (6) months and any Stock Options awarded under the LTIP not
         previously exercisable and vested shall become fully exercisable and
         vested.

                  (ii)     The restrictions and deferral limitations applicable
         to any Restricted Stock, Deferred Stock, Stock Purchase Rights and
         Other Stock-Based Awards, in each case to the extent not already vested
         under the LTIP, shall lapse and such shares shall be deemed fully
         vested.

                  (iii)    The value of all outstanding Awards, in each case to
         the extent vested, shall, unless otherwise determined by the Board in
         its sole discretion at or after grant but prior to any Change in
         Control, be cashed out on the basis of the Change in Control Price as
         of the date such Change in Control or such Potential Change in Control
         is determined to have occurred or such other date as the Board may
         determine prior to the Change in Control.

<PAGE>

         b.       Definition of "Change in Control". For purposes of Section
11(a), a "Change in Control" means the happening of any of the following:

                  (i)      When any "person" as defined in Section 3(a)(9) of
         the Exchange Act and as used in Section 13(d) and 14(d) thereof,
         including a "group" as defined in Section 13(d) of the Exchange Act but
         excluding the Company and any Subsidiary and any employee benefit plan
         sponsored or maintained by the Company or any Subsidiary (including any
         trustee of such plan acting as trustee), directly or indirectly,
         becomes the "beneficial owner" (as defined in Rule 13(d)-3 under the
         Exchange Act), of securities of the Company representing twenty percent
         (20%) or more of the combined voting power of the Company's then
         outstanding securities; or

                  (ii)     When, during any period of twenty-four (24)
         consecutive months during the existence of the LTIP, the individuals
         who, at the beginning of such period, constitute the Board (the
         "Incumbent Directors") cease for any reason other than death to
         constitute at least a majority thereof, provided, however, that a
         director who was not a director at the beginning of such twenty-four
         (24) month period shall be deemed to have satisfied such twenty-four
         (24) month requirement (and be an Incumbent Director) if such director
         was elected by, or on the recommendations or with the approval of, at
         least two-thirds of the directors who then qualified as Incumbent
         Directors either actually (because they were directors at the beginning
         of such twenty-four (24) month period) or by prior operations of this
         Section 11(b)(ii); or

                  (iii)    The occurrence of a transaction requiring stockholder
         approval for the acquisition of the Company by an entity other than the
         Company or a Subsidiary through purchase of assets, or by merger, or
         otherwise.

         c.       Definition of "Potential Change in Control". For purposes of
Section 11(a), a "Potential Change in Control" means the happening of any one of
the following:

                  (i)      The approval by stockholders of an agreement by the
         Company, the consummation of which would result in a Change in Control
         of the Company as defined in Section 11(b); or

                  (ii)     The acquisition of beneficial ownership, directly or
         indirectly, by an entity, person or group (other than the Company or a
         Subsidiary or any Company employee benefit plan (including any trustee
         or such plan acting as such trustee) or securities of the Company
         representing five percent (5%) or more of the combined voting power of
         the Company's outstanding securities and the adoption by the Board of a
         resolution to the effect that a Potential Change in Control of the
         Company has occurred for the purposes of the LTIP.

         d.       Definition of "Change in Control Price". For purposes of this
Section 11, "Change Control Price" means (i) the highest price per share paid in
any transaction reported on the National Association of Securities Dealers
Automated Quotation System, or (ii) if on a stock exchange, the highest price
per share on such exchange as reported in The Wall Street Journal, or (iii) if
not so reported, paid or offered in any bona fide transaction related to a
potential or actual Change in Control of the Company at any time during the
sixty (60) day period immediately preceding the occurrence of the Change in
Control period immediately preceding the occurrence of the Change in Control
(or, where applicable, the occurrence of the Potential Change in Control event),
in each case as determined by the Board except that, in the case of Incentive
Stock Options and Stock Appreciation Rights relating to Stock Options, such
price shall be based only on transactions reported for the date on which the
optionee exercises such Stock Appreciation Rights (or Limited Stock Appreciation
Rights) or, where applicable, the date on which a cashout occurs under Section
11(a)(ii).

<PAGE>

SECTION 12.       Amendment and Termination.

         The Board may amend, alter, or discontinue the LTIP, but no amendment,
alteration, or discontinuation shall be made which would impair the rights of an
optionee or participant under an Award theretofore granted, without the
optionee's or participant's consent, or which, without the approval of the
Company's stockholders, would:

         a.       except as generally provided in this LTIP, increase the total
number of shares reserved for the purpose of the LTIP;

         b.       change the pricing terms of Section 9(a);

         c.       change the Employees eligible to participate in the LTIP; or

         d.       extend the maximum option period under Section 5(d) of the
LTIP.

         The Board may amend the terms of any Stock Option or other Award
theretofore granted, prospectively or retroactively, but, subject to Section 3
above, no such amendment shall impair the rights of any holder without the
holder's consent. The Board may also substitute new Stock Options for previously
granted Stock Options (on a one-for-one or other basis), including previously
granted Stock Options having higher option exercise prices.

         Subject to the above provisions, the Board shall have broad authority
to amend the LTIP to take into account changes in applicable securities and tax
laws and accounting rules, as well as other developments.

SECTION 13.       Unfunded Status of LTIP.

         The LTIP is intended to constitute an "unfunded" plan for incentive and
deferred compensation. With respect to any payments not yet made to a
participant or optionee by the Company, nothing contained herein shall give any
such participant or optionee any rights that are greater than those of a general
creditor of the Company. In its sole discretion, the Board may authorize the
creation of trusts or other arrangements to meet the obligations created under
the LTIP to deliver Stock or payments in lieu of or with respect to Awards
hereunder, provided, however, that, unless the Board determines otherwise with
the consent of the affected participant, the existence of such trusts or other
arrangements is consistent with the "unfunded" status of the LTIP.

SECTION 14.       General Provisions.

         a. The Board may require each person purchasing shares of Stock
pursuant to a Stock Option or other Award under the LTIP to represent to and
agree with the Company in writing that the optionee or participant is acquiring
the shares without a view to distribution thereof. The certificates for such
shares may include any legend which the Board deems appropriate to reflect any
restrictions on transfer.

         All certificates for shares of Stock or other securities delivered
under the LTIP shall be subject to compliance with such stock-transfer orders
and other restrictions as the Board may deem advisable under the rules,
regulations, and other requirements of the Commission, any stock exchange upon
which the Stock is then listed, and any applicable Federal or state securities
law, and shall further be subject to the approval of counsel for the Company
with respect to such compliance. The Board may cause a legend or legends to be
put on any such certificates to make appropriate reference to such restrictions.

<PAGE>

         b.       Nothing contained in this LTIP shall prevent the Board from
adopting other or additional compensation arrangements, subject to stockholder
approval if such approval is required; and such arrangements may be either
generally applicable or applicable only in specific cases.

         c.       The adoption of the LTIP shall not confer upon any employee of
the Company or any Subsidiary or Affiliate any right to continue employment with
the Company or a Subsidiary or Affiliate, as the case may be, nor shall it
interfere in any way with the right of the Company or a Subsidiary or Affiliate
to terminate the employment of any of its employees at any time.

         d.       No later than the date as of which an amount first becomes
includible in the gross income of the participant for Federal income tax
purposes with respect to any Award under the LTIP, the participant shall pay to
the Company, or make arrangements satisfactory to the Board regarding the
payment of, any Federal, state, or local taxes of any kind required by law to be
withheld with respect to such amount. Unless otherwise determined by the Board,
withholding obligations may be settled with Stock, including Stock that is part
of the Award that gives rise to the withholding requirement. The obligations of
the Company under the LTIP shall be conditional on such payment or arrangements
and the Company and its Subsidiaries or Affiliates shall, to the extent
permitted by law, have the right to deduct any such taxes from any payment of
any kind otherwise due to the participant.

         e.       The actual or deemed reinvestment of dividends or dividend
equivalents in additional Restricted Stock (or in Deferred Stock or other types
of Awards) at the time of any dividend payment shall only be permissible if
sufficient shares of Stock are available under Section 3 for such reinvestment
(taking into account then outstanding Stock Options, Stock Purchase Rights and
other Awards).

         f.       The LTIP and all Awards made and actions taken thereunder
shall be governed by and construed in accordance with the laws of the
Commonwealth of Massachusetts.

SECTION 15.       Effective Date of LTIP.

         The LTIP shall be effective as of May 22, 1992 subject to the approval
of the LTIP by a majority of the votes cast by the holders of the Company's
Common Stock at the next annual stockholder's meeting in 1992. Any grants made
under the LTIP prior to such approval shall be effective when made (unless
otherwise specified by the Board at the time of grant), but shall be conditioned
on, and subject to, such approval of the LTIP by such stockholders.

SECTION 16.       Term of LTIP.

         No Award shall be granted pursuant to the LTIP on or after the tenth
anniversary of the date of stockholder approval or Board approval, whichever is
earlier, but Awards granted prior to such tenth anniversary may extend beyond
that date.

SECTION 17.       Definitions.

         For purposes of the LTIP, the following terms shall be defined as set
forth below:

         a.       "Affiliate" means any entity other than the Company and its
Subsidiaries that is designated by the Board as a participating employer under

entity.

of such year-end date (as adjusted by the Board for subsequent events).

         e.       "Cause" shall have the meaning set forth in Section 5(i)
above.

                              EMPLOYMENT AGREEMENT

         THIS AGREEMENT, dated as of April 1, 1995, is between NATIONAL DENTEX
CORPORATION, a Massachusetts corporation (the "Company"), and RICHARD F. BECKER,
JR. (the "Executive").

         WHEREAS, the Company desires to continue to retain the services of the
Executive, and the Executive desires to continue to be employed by the Company
upon the terms and conditions hereinafter set forth;

         NOW, THEREFORE, the parties agree as follows:

         1.       SCOPE OF EMPLOYMENT.

                  (a)      Nature of Services. Executive shall diligently
         perform the duties and assume the responsibilities of the position of
         Vice President, Corporate Controller and Assistant Treasurer of the
         Company and such additional executive duties and responsibilities as
         shall from time to time be assigned to him by the Board of Directors.

                  (b)      Extent of Services. Executive shall devote
         substantially all his working time and attention and his best efforts
         to the performance of his duties and responsibilities under this

         where he is not obligated or required to, and shall not in fact, devote

         only that the Board of Directors shall have the right to limit such
         services as director or such participation whenever the Board of
         Directors shall believe that the time spent on such activities
         infringes in any material respect upon the time required by Executive
         for the performance of his duties under this Agreement or is otherwise
         incompatible with those duties.

         payroll practices. During the Employment Period, as defined in Section

         any, Executive receives under any short term or long term disability
         insurance policies paid for by Company and related to Executive's
         employment hereunder. The Executive's salary may be increased from time
         to time by the Board of Directors.

         or other conditions of participation) in such fringe benefits as are
         generally made available to executives of the Company, including
         without limitation health, disability and life insurance (collectively,
         the "Insurance Benefits") and the Company's stock option and stock
         purchase plans.

                  (d)      Expense Reimbursement. The Company will reimburse
         Executive for all reasonable and necessary expenses incurred by him in

         continue to maintain health insurance benefits comparable to the health
         insurance benefits provided to the Executive prior to his death, and
         provided for executives of the Company generally during such period,
         and upon substantially similar terms and conditions as were provided to
         Executive generally. If under any of the terms of any group policy
         maintained by the Company such coverage is not properly obtainable, the
         Executive's widow or legal representatives, as applicable, may elect to

         Executive pursuant to the Company's long-term disability plan and the
         Executive's then current Base Salary and Bonus, payable at the same

         Executive.

                  (e)      For purposes of determining the amount of the Bonus
         payable to the Executive pursuant to Sections 4(a), (b) and (d) above,
         the amount of the Bonus shall be equal to the average of the prior two
         (2) annual Bonuses payable to the Executive for and in respect to the
         fiscal years of the Company ending prior to or coinciding with the

ordinary course of performing Executive's duties as an employee of the Company
or except as may be in the public domain through no fault of Executive's, and

patentable or registrable under copyright or similar statutes or subject to
analogous protection) ("Inventions") that relates to any of the products or
services being developed, manufactured or sold by the Company or which may
conveniently be used in relation therewith, or results from tasks assigned
