     7.   Indemnity and Escrow.

          (a)  Escrow.  Upon the effective date of the Merger (the "Effective
Date") and receipt of the cash consideration for certain of the Shares owned by
Shareholders immediately prior to the Effective Date, Shareholders agree that
they will deposit, and hereby direct the Exchange Agent (as defined in the
Merger Agreement) to deposit, $4,250,000 in cash into an escrow account (the
"Escrow") established pursuant to the terms of that certain Escrow Agreement by
and among HK, Shareholders and an escrow agent (the "Escrow Agent")
substantially in the form of Exhibit A attached hereto. The Escrow will be
available to satisfy any amounts owing to HK pursuant to Section 7(b), and,
other than pursuant to this Section 7, HK and its affiliates shall not assert,
directly or indirectly, any claim, proceeding or action against the Shareholders
with respect to the Merger Agreement or any action or inaction of the
Shareholders acting in their capacity as officers, directors, shareholders or
employees of the Company occurring prior to the Merger (except claims relating
to or arising out of the fraudulent acts or fraudulent omissions by any of the
Shareholders). Except as otherwise permitted under the Escrow Agreement,
assuming consummation of the transactions contemplated herein and in the Merger
Agreement, after the Effective Date, Shareholders shall not assert, directly or
indirectly, any claim, proceeding or action against the Company, HIG-HK
Investment, Inc. ("Parent") or their affiliates with respect to this Agreement
(other than to enforce this Section 7), the Merger Agreement or any action or
inaction of the Company, Parent or any of their affiliates relating to or in
connection with the Company, the Merger Agreement or this Agreement (except
claims relating to or arising out of the fraudulent acts or failure to act by
Parent or its affiliates).

          (b)  Indemnification of the Company by Shareholders. Subject to the
limitations set forth in Section 7(c), after the Effective Date, Shareholders,
jointly and severally, will indemnify HK and its affiliates, officers,
directors, employees, agents, representatives, successors and assigns and, to
the extent Parent is not made whole, Parent (each, an "Indemnitee") and hold
each Indemnitee harmless from and against any loss, liability, deficiency,
damage or expense (including reasonable legal expenses and costs and any cost or
expense arising from or incurred in connection with any action, suit,
proceeding, claim or judgement relating solely to any matter described in this
Section 7(b), or in enforcing the indemnity provided by this Section 7(b)) (any
such amount being a "Loss"), which such Indemnitee may suffer, sustain or become
subject to, as a result of any breach by (i) the

                                       5
<PAGE>

Company of any representation or warranty set forth in Article 3 of the Merger
Agreement or (ii) the Shareholders of any representation or warranty set forth
in this Agreement (in each case, determined without regard to any qualifications
therein referencing the terms "materiality," "Material Adverse Effect" or
"knowledge," or other term of similar import or effect).

          (c)  Limitations. Shareholders' indemnification obligation set forth
in Section 7(b) is subject to the following limitations:

               (i)    Survival and Notice.  Notwithstanding Section 8.1 of the
Merger Agreement, for purposes of this Agreement all representations and
warranties of the Company in the Merger Agreement shall survive the Closing Date
and the consummation of the transactions contemplated hereby and shall not be
affected by any examination made for or on behalf of any party, the knowledge of
any of such party's officers, directors, stockholders, employees, or agents, or
the acceptance of any certificate or opinion. Notwithstanding the foregoing,
with respect to the representations and warranties contained in Article 3 of the
Merger Agreement, HK shall not be entitled to recover for any Loss pursuant to
Section 7(b) unless written notice of a claim thereof is delivered to the
Shareholders before the Applicable Limitation Date. For purposes of this
Agreement, the term "Applicable Limitation Date" shall mean March 31, 2001;
provided that the Applicable Limitation Date with respect to any Loss arising
from or related to a breach of the representations and warranties of the Company
set forth in Section 3.1 (Organization and Qualifications; Subsidiaries), 3.2
(Capitalization; Subsidiaries), 3.3 (Authority Relative to this Agreement), and
3.9 (Taxes) of the Merger Agreement shall be the date of expiration of the
statute of limitations applicable to the statute, regulation or other authority
which related to such Loss (including extensions or waivers thereof). All
statements as to factual matters contained in any certificate or other
instrument delivered at the Closing on behalf any Shareholder, the Company or
its Subsidiaries shall be deemed to be representations and warranties by such
party hereunder as of the Closing Date.

               (ii)   Dollar Basket.  Shareholders shall not be obligated to
indemnify the Indemnities for any single Loss covered by Section 7(b)
(consolidating into any single Loss any series of related events, factors or
circumstances giving rise to liability on the same or a substantially related
basis) unless such Loss exceeds $250,000, in which case Shareholders shall be
obligated to indemnify the Indemnities for the full amount of such Loss (subject
to the other limitations set forth in clauses (i) and (ii) of this Section
7(c)).

               (iii)  Cap.  An Indemnitee's remedy for any indemnification claim
against the Shareholders pursuant to Section 7(b) shall be limited to and
satisfied solely from the Escrow; provided that with respect to any Loss arising
from or related to a breach of the representations and warranties of the Company
set forth in Section 3.1 (Organization and Qualifications; Subsidiaries), 3.2
(Capitalization; Subsidiaries), 3.3 (Authority Relative to this Agreement), and
3.9 (Taxes), or in the case of fraud, an Indemnitee's remedy for any

                                       6
<PAGE>

     indemnification claim shall not be limited to the Escrow and the
Shareholders will be obligated to indemnify the Indemnitees for Losses up to the
Merger Consideration received by the Shareholders.

          (d)  Indemnification Procedures.

               (i)    Notice of Claim.  Any Person making a claim for
indemnification pursuant to Section 7(b) above (an "Indemnified Party") must
give the Party from whom indemnification is sought (an "Indemnifying Party")
written notice of such claim describing such claim and the nature and amount of
such Loss (to the extent that the nature and amount of such Loss is known at
such time) (an "Indemnification Claim Notice") promptly after the Indemnified
Party receives any written notice of any action, lawsuit, proceeding,
investigation or other claim (a "Proceeding") against or involving the
Indemnified Party or otherwise discovers the liability, obligation or facts
giving rise to such claim for indemnification; provided that the failure to
notify or delay in notifying an Indemnifying Party will not relieve the
Indemnifying Party of its obligations pursuant to Section 7(b), except to the
extent that (and only to the extent that) such failure shall have caused the
damages for which the Indemnifying Party is obligated to be greater than such
damages would have been had the Indemnified Party given the Indemnifying Party
prompt notice hereunder.

               (ii)   Control of Defense: Conditions. With respect to the
defense of any Proceeding against or involving an Indemnified Party in which the
party in question seeks only the recovery of a sum of money for which
indemnification is provided in Section 7(b), at its option an Indemnifying Party
may appoint as lead counsel of such defense any legal counsel selected by the
Indemnified Party; provided that before the Indemnifying Party assumes control
of such defense it must first

               (A)  enter into an agreement with the Indemnified Party (in form
     and substance satisfactory to the Indemnified Party) pursuant to which the
     Indemnifying Party agrees to be fully responsible (with no reservation of
     any rights other than the right to be surrogate to the rights of the
     Indemnified Party) for all Losses relating to such Proceeding and
     unconditionally guarantees the payment and performance of any liability or
     obligation which may arise with respect to such Proceeding or the facts
     giving rise to such claim for indemnification, and

               (B)  furnish the Indemnified Party with evidence that the
     Indemnifying Party, in the Indemnified Party's sole judgment, is and will
     be able to satisfy any such liability.

               (iii)  Control of Defense: Exceptions, etc. The Indemnified Party
will be entitled to participate in the defense of such claim and to employ
counsel of its choice for

                                       7
<PAGE>

     such purpose at its own expense; provided that notwithstanding the
foregoing, the Indemnifying Party will bear the reasonable fees and expenses of
such separate counsel incurred prior to the date upon which the Indemnifying
Party effectively assumes control of such defense. The Indemnifying Party will
not be entitled to assume control of the defense of such claim, and will pay the
reasonable fees and expenses of legal counsel retained by the Indemnified Party,
if

               (A)  the Indemnified Party reasonably believes that an adverse
          determination of such Proceeding could be detrimental to or injure the
          Indemnified Party's reputation or future business prospects,

               (B)  the Indemnified Party reasonably believes that there exists
          or could arise a conflict of interest which, under applicable
          principles of legal ethics, could prohibit a single legal counsel from
          representing both the Indemnified Party and the Indemnifying Party in
          such Proceeding, or

               (C)  a court of competent jurisdiction rules that the
          Indemnifying Party has failed or is failing to prosecute or defend
          vigorously such claim; and

The Indemnifying Party must obtain the prior written consent of the Indemnified
Party (which the Indemnified Party will not unreasonably withhold) prior to
entering into any settlement of such claim or Proceeding or ceasing to defend
such claim or Proceeding.

               (iv)   Payments.  Any payment pursuant to a claim for
     indemnification shall be made not later than thirty (30) days after receipt
     by the Indemnifying Party of written notice from the Indemnified Party
     stating the amount of the claim, unless the claim is subject to defense as
     provided in Section 7(d)(v) or is otherwise disputed by the Indemnifying
     Party, in which case payment shall be made not later than 30 days after the
     amount of the claim is finally determined in accordance with Section
     7(d)(v). Any payment required under this Section 7(d)(iv) shall bear
     interest at 8% per annum or, if less, the maximum rate permitted by
     applicable usury laws from the date that the Indemnified Party incurred the
     Loss for which indemnification is sought. Interest on any such unpaid
     amount shall be compounded monthly, computed on the basis of a 365-day year
     and shall be payable on demand. In addition, such party shall reimburse the
     other party for any and all costs or expenses of any nature or kind
     whatsoever (including but not limited to all attorneys' fees) incurred in
     seeking to collect such Losses.



               (v)    Treatment of Indemnification Payments. Each Party will
     treat all payments made pursuant to Section 7(b) as adjustments to the
     purchase price paid for the Shareholders' Non-Rollover Shares (as defined
     in the Merger Agreement) in connection with consummation of the Merger for
     all purposes. Each Party agrees to use reasonable efforts to seek recovery
     under any insurance coverage which such Party may have in respect of any

                                       8
<PAGE>

     Loss; provided that, to the extent not already taken into account, a
     Party's Loss will include any increased premium which results from seeking
     such recovery or the occurrence or existence of any fact or circumstance
     giving rise to such Loss.

               (vi)   Other Indemnification Provisions.  Each Shareholder hereby
     agrees that he will not make any claim for indemnification hereunder
     against the Company by reason of the fact that he was a shareholder,
     director, officer, employee, or agent of the Company or was serving at the
     request of the Company as a partner, trustee, director, officer, employee,
     or other agent of another entity (whether such claim is for judgments,
     damages, penalties, fines, costs, amounts paid in settlement, losses or
     expenses) with respect to any action, suit, proceeding, complaint, claim,
     or demand brought by the Company against such Shareholder if such action,
     suit, proceeding, complaint, claim or demand is pursuant to this Agreement;
     it being understood that the foregoing limitation is not intended to apply
     to any indemnification obligations owed to Shareholders with respect to any
     action, suit, proceeding, complaint, claim or demand unrelated to this
     Agreement and the transactions contemplated hereby. Each Shareholder hereby
     acknowledges that he will have no claims or right to contribution or
     indemnity from the Company with respect to amounts paid by such Shareholder
     pursuant to Section 7(b).

          (e)  Arbitration Procedures.

               (i)    Each Party agrees that the arbitration procedure set forth
     below shall be the sole and exclusive method for resolving and remedying
     claims for money damages arising out of the provisions of Section 7(b) (the
     "Disputes"). Nothing in this Section 7(e) shall prohibit a party hereto
     from instituting litigation to enforce any Final Determination (as defined
     below) or availing itself of the other remedies set forth in Section 7(f)
     below. The Parties hereby agree and acknowledge that, except as otherwise
     provided in this Section 7(e) or in the Commercial Arbitration Rules of the
     American Arbitration Association as in effect from time to time, the
     arbitration procedures and any Final Determination hereunder shall be
     governed by, and shall be enforced pursuant to the Uniform Arbitration Act,
     9 U.S.C. ss. 1 et seq.

               (ii)   In the event that any Party asserts that there exists a
     Dispute, such Party shall deliver a written notice to each other Party
     involved therein specifying the nature of the asserted Dispute and
     requesting a meeting to attempt to resolve the same. If no such resolution
     is reached within ten business days after such delivery of such notice, the
     Party delivering such notice of Dispute (the "Disputing Person") may,
     within 30 days after delivery of such notice, commence arbitration
     hereunder by delivering to each other Party involved therein a notice of
     arbitration (a "Notice of Arbitration") and by filing a copy of such Notice
     of Arbitration with the New York office of the American Arbitration
     Association. Such Notice of Arbitration shall specify the matters as to
     which arbitration is sought, the nature of any Dispute, the claims of each
     Party to the arbitration and shall specify the amount and

                                       9
<PAGE>

     nature of any damages, if any, sought to be recovered as a result of any
     alleged claim, and any other matters required by the Commercial Arbitration
     Rules of the American Arbitration Association as in effect from time to
     time to be included therein, if any.

               (iii)  The Disputing Party, on the one hand, and the other
     Parties involved therein, on the other hand, each shall select one non-
     neutral arbitrator expert in the subject matter of the Dispute (the
     arbitrators so selected shall be referred to herein as the "Disputing
     Party's Arbitrator" and the "Non-Disputing Party's Arbitrator,"
     respectively). In the event that either Party fails to select an arbitrator
     as set forth herein within ten (10) business days from the delivery of a
     Notice of Arbitration, then the matter shall be resolved by the arbitrator
     selected by the other party. The Disputing Party's Arbitrator and the Non-
     Disputing Party's Arbitrator shall select a third independent, neutral
     arbitrator expert in the subject matter of the dispute, and the three
     arbitrators so selected shall resolve the matter according to the
     procedures set forth in this Section 7(e). If the Disputing Party's
     Arbitrator and the Non-Disputing Party's Arbitrator are unable to agree on
     a third arbitrator within twenty (20) days after their selection, the
     American Arbitration Association shall select the third arbitrator.

               (iv)   The arbitrator(s) selected pursuant to subsection (iii)
     above will determine the allocation of the costs and expenses of
     arbitration (including, without limitation, each Party's attorneys' fees
     and cost of investigation) based upon the ratio of the portion of the
     contested amount not awarded to each Party to the amount contested by such
     Party. For example, if the Disputing Party submits a claim for $1,000 and
     if the other Parties involved in the Dispute contest only $500 of the
     amount claimed by the Disputing Party, and if the arbitrator(s) ultimately
     resolves the dispute by awarding the Disputing Party $300 of the $500
     contested, then the costs and expenses of arbitration will be allocated 40%
     (i.e., 200 / 500) to the Disputing Party and 60% (i.e., 300 / 500) to the
     other Parties involved in the Dispute.

               (v)    The arbitration shall be conducted under the Commercial
     Arbitration Rules of the American Arbitration Association as in effect from
     time to time, except as otherwise set forth herein or as modified by the
     agreement of all of the Parties. The arbitration shall be conducted in New
     York, New York. The arbitrators shall so conduct the arbitration that a
     final result, determination, finding, judgment and/or award (the "Final
     Determination") is made or rendered as soon as practicable, but in no event
     later than 60 days after the delivery of the Notice of Arbitration nor
     later than 10 business days following completion of the arbitration. The
     Final Determination must be agreed upon and signed by the sole arbitrator
     or by at least two of the three arbitrators (as the case may be). The Final
     Determination shall be final and binding on all Parties and there shall be
     no appeal from or reexamination of the Final Determination, except for
     fraud, perjury, evident partiality or misconduct by an arbitrator
     prejudicing the rights of any Party and to correct manifest clerical
     errors.

                                       10
<PAGE>

               (vi)   A Party may enforce any Final Determination in any state
     or federal court having jurisdiction over the dispute. For the purpose of
     any action or proceeding instituted with respect to any Final
     Determination, each Party hereby irrevocably submits to the jurisdiction of
     such courts, irrevocably consents to the service of process by registered
     mail or personal service and hereby irrevocably waives, to the fullest
     extent permitted by law, any objection which it may have or hereafter have
     as to personal jurisdiction, the laying of the venue of any such action or
     proceeding brought in any such court and any claim that any such action or
     proceeding brought in such court has been brought in an inconvenient forum.

               (vii)  Any party required to make a payment pursuant to this
     Section 7(e) shall pay the party entitled to receive such payment within
     three days of the delivery of the Final Determination to such responsible
     party. If any party shall fail to pay the amount of damages, if any,
     assessed against it within 10 days of the delivery to such party of such
     award, the unpaid amount shall bear interest from the date of such delivery
     at 14% per annum or, if less, the maximum rate permitted by applicable
     usury laws. Interest on any such unpaid amount shall be compounded monthly,
     computed on the basis of a 365-day year and shall be payable on demand. In
     addition, such party shall reimburse the other party for any and all costs
     or expenses of any nature or kind whatsoever (including but not limited to
     all attorneys' fees) incurred in seeking to collect such damages or to
     enforce any such award.

          (f)  Remedies.  The foregoing indemnification provisions shall be the
exclusive remedy for the matters set forth in Section 7(b), except in the case
of fraud, in which case each Indemnitee shall be able to seek any statutory,
equitable or common law remedy it may have.

     8.   Non-Competition.  As a condition precedent to HK's obligation to enter
into and perform its obligations under the Merger Agreement, each Shareholder
agrees that:

          (a)  For a period of five (5) years after the Closing Date (the "Non-
Competition Period"), such Shareholder shall not, directly or indirectly, either
for himself or for any other person, "participate" anywhere in the world in the
business as currently conducted by or as proposed to be conducted by the Company
and its Subsidiaries, including but not limited to the design, manufacture,
marketing, distribution, licensing and sale of children's and teen's (i.e. ages
0-21) apparel or accessories (the "Business"). For purposes of this Agreement,
the term "participate" includes any direct or indirect interest in any
enterprise, whether as an officer, director, employee, partner, sole proprietor,
agent, representative, independent contractor, consultant, franchisor,
franchisee, creditor, owner or otherwise; provided, that the term "participate"
shall not include ownership of less than 5% of the stock of a publicly-held
corporation whose stock is traded on a national securities exchange or in the
over-the-counter market or the continued participation by the Shareholder on the
Board of Directors of any company in which he serves as of the date hereof.

                                       11
<PAGE>

          (b)  During the Non-Competition Period, such Shareholder will not
divulge or appropriate for his own use, or for the use of any third party, any
secret or confidential information or knowledge obtained by such Shareholder
concerning the Business. This obligation of secrecy shall not apply to
information which (i) is or becomes part of the public domain other than through
breach of this Agreement or through the fault of such Shareholder from an
unaffiliated source, which source has no obligation of secrecy to the Company,
(ii) is required to be disclosed by law or government order (but only to the
extent so required), or (iii) is used by such Shareholder in any other lines of
business (but only to the extent so used).

          (c)  During the five-year period following the Closing Date, such
Shareholder shall not solicit the employment (in any capacity) of or hire
directly or through another entity any employee of the Business or any person
who was an employee of the Business during the one year period immediately
preceding the date of such solicitation or hire without the prior written
consent of the Company and Parent.

          (d)  If at the time of enforcement of this Section 8, a court holds
that the duration, scope, geographic area or other restrictions stated herein
are unreasonable under circumstances then existing, the parties agree that the
maximum duration, scope, geographic area or other restrictions deemed reasonable
under such circumstances by such court shall be substituted for the stated
duration, scope, geographic area or other restrictions.

          (e)  Such Shareholder recognizes and affirms that in the event of
breach of any of the provisions of this Section 8, money damages would be
inadequate and the Company and its affiliates would have no adequate remedy at
law. Accordingly, such Shareholder agrees that the Company and its affiliates
shall have the right, in addition to any other rights and remedies existing in
their favor, to enforce their rights and such Shareholder's obligations under
this Section 10 not only by an action or actions for damages, but also by an
action or actions for specific performance, injunctive and/or other equitable
relief in order to enforce or prevent any violations (whether anticipatory,
continuing or future) of the provisions of Section 8 (including, without
limitation, the extension of the Non-Competition Period by a period equal to (i)
the length of the violation of this Section 8 plus (ii) the length of any court
proceedings necessary to stop such violation). In the event of a breach or
violation by such Shareholder of any of the provisions of this Section 8 the
running of the Non-Competition Period (but not of such Shareholder's obligations
under this Section 8) shall be tolled with respect to such Shareholder during
the continuance of any actual breach or violation.

     9.   Further Assurances.  Each Shareholder will, from time to time, execute
and deliver, or cause to be executed and delivered, such additional or further
transfers, assignments, endorsements, consents and other instruments as HK may
reasonably request for the purpose of effectively carrying out the transactions
contemplated by this Agreement and to vest the power to vote such Shareholder's
Shares as contemplated by Section 3. HK agrees to use reasonable efforts to
take, or cause to be taken, all actions necessary to comply promptly with all
legal requirements

                                       12
<PAGE>

that may be imposed with respect to the transactions contemplated by this
Agreement (including legal requirements of the HSR Act).

     10.  Termination and Alternate Transaction Fee. The Shareholders agree that
in the event the Company is required to pay a Termination Fee pursuant to
Section 7.3 of the Merger Agreement, the Shareholders shall jointly and
severally pay to HK $1.5 million in cash within ten days of the date such
Termination Fee becomes due and owing. In addition to the above payment, the
Shareholders agree that in the event the Company is required to pay a
Termination Fee pursuant to Section 7.3 of the Merger Agreement, the
Shareholders shall jointly and severally pay to HK in cash an Alternate
Transaction Fee at the closing of an Alternate Transaction. An "Alternate
Transaction" shall mean a transaction that closes within twelve months of the
date of the termination of the Merger Agreement wherein any of the Shareholders
sell shares in the Company to a person other than HK or an affiliate of HK. The
"Alternative Transaction Fee" shall mean the product of (i) 90%, multiplied by
(ii) the total number of shares sold by the Shareholders in an Alternate
Transaction, multiplied by (iii) the excess of (a) the price per share to be
received plus any other consideration to be received in any form (including
without limitation earn-out payments, bonus payments, excess compensation
payments, etc.) by the Shareholders in an Alternate Transaction over (b) $7.164.

     11.  Assignment; Binding Effect.  Neither this Agreement nor any of the
rights, interests or obligations hereunder shall be assigned by any of the
parties hereto (whether by operation of law or otherwise) without the prior
written consent of the other parties. Subject to the preceding sentence, this
Agreement shall be binding upon, inure to the benefit of, and be enforceable by,
the parties hereto and their respective successors and assigns. Notwithstanding
the foregoing, HK shall have the right to assign its rights, interests and
obligations hereunder to Parent and any of its affiliates at its sole option and
without the prior written consent of the other parties hereto; provided that no
such assignment shall relieve HK of its obligations hereunder. Notwithstanding
anything contained in this Agreement to the contrary, nothing in this Agreement,
expressed or implied, is intended to confer on any person other than the parties
hereto or their respective heirs, successors, executors, administrators and
assigns any rights, remedies, obligations or liabilities under or by reason of
this Agreement.

     12.  General Provisions.

          (a)  Payments.  All payments required to be made to any party to this
Agreement shall be made by Wire Transfer to an account designated by such party
at least one trading day prior to such payment.

          (b)  Expenses.  Subject to the terms of the Merger Agreement, all
costs and expenses incurred in connection with this Agreement and the
transactions contemplated hereby shall be paid by the party incurring such
expense.

indicated. The headings

                                       14
<PAGE>

contained in this Agreement are for reference purposes only and shall not affect
in any way the meaning or interpretation of this Agreement. Wherever the words
"include", "includes" or "including" are used in this Agreement, they shall be
deemed to be followed by the words "without limitation".

          (f)  Counterparts.  This Agreement may be executed in two or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when two or more counterparts have been signed by each of
the parties and delivered to the other parties, it being understood that all
parties need not sign the same counterpart.

          (g)  Entire Agreement; No Third-Party Beneficiaries. This Agreement
(including the documents and instruments referred to herein) (i) constitutes the
entire agreement and supersedes all prior agreements and understandings, both
written and oral, among the parties with respect to the subject matter hereof
including, without limitation, the letter agreement dated July 9, 1999 between
H.I.G. Capital, LLC and the Majority Shareholders (as such term is defined
therein)and (ii) is not intended to confer upon any person other than the
parties hereto any rights or remedies hereunder.

          (h)  Governing Law.  This Agreement shall be governed and construed in
accordance with the laws of the State of New York without regard to any
applicable conflicts of law.

          (i)  Publicity.  Except as otherwise required by law, court process or
the rules of a national securities exchange or the Nasdaq National Market or as
contemplated or provided in the Merger Agreement, for so long as this Agreement
is in effect, neither any Shareholder nor HK shall issue or cause the
publication of any press release or other public announcement with respect to
the transactions contemplated by this Agreement or the Merger Agreement without
the consent of the other parties, which consent shall not be unreasonably
withheld.

     13.  Shareholder Capacity.  No person executing this Agreement who is or
becomes during the term hereof a director or officer of the Company makes any
agreement or understanding herein in his or her capacity as such director or
officer. Each Shareholder signs solely in his capacity as the record holder and
beneficial owner of, or the trustee of a trust whose beneficiaries are the
beneficial owners of, such Shareholder's Shares and nothing herein shall limit
or affect any actions taken by a Shareholder in its capacity as an officer or
director of the Company to the extent specifically permitted by the Merger
Agreement.

     14.  Enforcement.  The parties agree that irreparable damage would occur in

accordingly agreed that the parties shall be entitled to an injunction or
injunctions to prevent breaches of this Agreement and to enforce specifically
the terms and provisions of this Agreement in a court of the United States. This
being in addition to any other

                                       15
<PAGE>

remedy to which they are entitled at law or in equity. In addition, each of the
parties hereto waives any right to trial by jury with respect to any claim or
proceeding related to or arising out of this Agreement or any of the
transactions contemplated hereby.

     15.  Severability.  If any term, provision, covenant or restriction of this
Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remainder of the terms, provisions, covenants and
restrictions of this Agreement shall remain in full force and effect and shall
in no way be affected, impaired or invalidated. If any provision of this
Agreement is so broad as to be unenforceable, the provision shall be interpreted
to be only so broad as is enforceable.

     16.  Termination.  The provisions of Sections 3, 4, 5, 6, 7, 8 and 9 shall
terminate automatically and be of no further force and effect upon the
termination of the Merger Agreement.
