benefit of Sealed Air that all inventions, discoveries, works subject to
copyright, techniques, systems, methods, processes, improvements, developments,

information (collectively, "Rights") that Consultant may, either solely or
jointly with others and whether or not during the Consultant's working hours,
acquire, discover, invent, originate, make, conceive or have rights to with
respect to any project relating to his services performed for Sealed Air, shall
be the sole property of Sealed Air. The Consultant shall disclose to Sealed Air
all such Rights conceived prior to or during the term of his retention hereunder

covenants and agrees that he will, at the request of Sealed Air, promptly
execute such assignments, applications and other documents and provide such
assistance as Sealed Air may reasonably request in order to vest title to such
Rights in Sealed Air or its designee and to enable it to obtain, maintain and
enforce its exclusive right, title and interest in and to such Rights throughout
the world.

benefit of a competitor of Sealed Air or (ii) act as an officer, director,
employee, consultant, partner or stockholder owning more than five percent of a
corporation, business or enterprise that is in the business of designing,
developing, manufacturing, selling, servicing or promoting a product that
competes with any of the products manufactured, sold or under development by
Sealed Air during the Consultant's employment with or retention as a consultant
by Sealed Air. The Consultant acknowledges and represents that his background
and experience adequately qualify him to engage in other profitable lines of
endeavor and that he will not be subject to undue hardship by reason of this
non-competition commitment.

     (e) Survival of Agreements. The agreements contained or referred to in
this Section 5 shall survive the termination or expiration of the Consultant's
retention with Sealed Air. No such termination or expiration shall in any event
discharge or extinguish any claims or rights of either party with respect to
any breach or default of this Agreement prior to the date of any such
termination.

     Section 6. Additional Representations and Agreements

     (a) The Consultant represents and agrees that (a) he has had access by
reason of his service as Chief Executive Officer and Chairman of the Board of
Directors to sufficient information concerning Sealed Air to enable him to
evaluate the merits and risks of the acquisition of the Shares under this
Agreement, (b) he has such knowledge and experience in financial and business
matters that he is capable of evaluating such acquisition, (c) it is his
intention to acquire and hold the Shares for investment and not for the resale
or distribution thereof, (d) he will comply with the Securities Act of 1933, as
amended (the "Securities Act"), and the Securities Exchange Act of 1934, as
amended (the "Securities Exchange Act"), and (e) he will indemnify Sealed Air
for any costs, liabilities and expenses that it may sustain because of any
violation of the Securities Act or the Securities Exchange Act due to any act
or omission on his part with respect to the Shares.

     (b) The Shares may not be sold, transferred or otherwise disposed of unless
either (i) the Shares shall have been registered by Sealed Air under the
Securities Act; (ii) Sealed Air shall have received either a "no action" letter
from the Securities and Exchange Commission or an opinion of counsel acceptable
to Sealed Air to the effect that such sale, transfer or disposition may be made
without such registration, or (iii) such sale, transfer or disposition is made
under

<PAGE>

                                       4

Rule 144 under the Securities Act, and Sealed Air shall have received such
documentation related thereto as counsel to Sealed Air deems acceptable.

     (c) The Consultant agrees that Sealed Air may require that any certificate
evidencing the Shares bear a restrictive legend and be subject to stop-transfer
orders or other actions intended to ensure compliance with the Securities Act
or any other applicable regulatory measures.

     Section 7. Sealed Air's Right to Reacquire the Shares.

     (a) Option to Reacquire. During the Term, the Shares shall be subject to
an option (the "Option") in favor of Sealed Air to reacquire the Shares.
Neither the Shares nor any interest in such Shares may be sold, transferred or
encumbered until the Option to reacquire such Shares may no longer become
exercisable. The Option shall cease to be exercisable as to all Shares at the
end of the Term or upon the earlier termination of this Agreement under
subsections (i), (ii) or (iii) of Section 4. The Option shall become
exercisable only if (i) this Agreement should be terminated under subsection
(iv) of Section 4 or (ii) the Consultant should materially breach his
obligations under this Agreement. If Sealed Air notifies the Consultant that
Sealed Air intends to exercise the Option, then the Consultant will deliver the
certificates representing the Shares to Sealed Air within 30 days following
written notice of exercise by Sealed Air. The Consultant shall not be entitled
to be paid any cash or other consideration upon or in connection with the
reacquisition of Shares upon Sealed Air's exercise of the Option.

     (b) Legending of Certificates. Every certificate representing Shares
issued pursuant to this Agreement shall, so long as the Option remains
exercisable, bear a legend in substantially the following form and shall have
in effect a stop-transfer order with respect thereto:

          This certificate and the shares represented hereby are held subject
     to the terms of an agreement between T. J. Dermot Dunphy and Sealed Air
     Corporation pursuant to which these shares are subject to an option in
     favor of Sealed Air Corporation to reacquire such shares upon the
     occurrence of certain events and pursuant to which neither these shares
     nor any interest therein may be sold, transferred or encumbered until the
     expiration of such option. If such option is exercised, the holder of the
     shares represented by this certificate will have no further rights with
     respect to such shares, and this certificate will be deemed void. A copy
     of such Agreement is available for inspection at the executive offices of
     Sealed Air Corporation.

Upon expiration of the Option, the Consultant may surrender to Sealed Air the
certificate or certificates representing such Shares in exchange for a new
certificate or certificates, free of the above legend.

     (c) Adjustments. In the event of changes in the Common Stock after the
date of this Agreement by reason of any stock dividend, split-up, combination
of shares, reclassification,

<PAGE>

                                       5

recapitalization, merger, consolidation, reorganization or liquidation (i) the
terms and conditions of this Agreement shall apply to any securities issued in
connection with any such change with respect to the Shares and (ii) appropriate
adjustments shall be made as to the securities to be delivered upon the exercise
of the Option.

     Section 8. Equitable Remedies, Etc. The Consultant acknowledges that the
provisions of Section 5 of this Agreement are reasonably necessary to protect
the legitimate business interests of Sealed Air and that any violation of any
of such provision will result in irreparable injury to Sealed Air for which
damages will not be an adequate remedy. The Consultant therefore agrees that,
if he violates or threatens to violate any of such provisions, in addition to
any compensatory, punitive or other damages that Sealed Air shall be entitled
to recover, Sealed Air shall be entitled to preliminary and injunctive relief
and any other available equitable remedies in connection with such violation or
threatened violation. The prevailing party shall be entitled to recover from
the other party the costs of obtaining legal or equitable relief, including
reasonable attorneys' fees, upon breach of any provision of this Agreement.

     Section 9. Contingent Stock Awards. On August 14, 1997 and April 2, 1998
the Consultant was awarded 60,000 and 80,000 shares, respectively, of Common
Stock under the Contingent Stock Plan of Sealed Air Corporation that remain
subject to Sealed Air's option to repurchase such shares should his employment
end before October 13, 2000 and June 1, 2001, respectively. The Organization
and Compensation Committee of Sealed Air's Board of Directors has agreed to
waive the exercise of such option upon the termination of his employment on
February 29, 2000, on the condition that such option shall remain exercisable
as to each award during the remainder of its respective option period as
provided under such Plan if his service as a consultant to and a director of
Sealed Air should cease during that time other than as a result of the
Consultant's death or permanent and total disability, and the Consultant agrees
to such continued option.

     Section 10. Severability. Each provision of this Agreement is separable
from every other provision of this Agreement, and each part of each provision
of this Agreement is separable from every other part of such provision. If the
scope or enforceability of this Agreement is in any way disputed at any time, a
court or other trier of fact may modify and enforce the provisions hereof to
the extent it believes to be reasonable under the circumstances existing at
such time.

     Section 11. Consultant Status. The Consultant is an independent contractor
and shall not be deemed by virtue of this Agreement to be an employee of Sealed
Air or to be entitled to receive any compensation as an employee or to
participate in any employee benefit program except for such as are expressly
provided for in this Agreement, provided, that this shall not affect his
eligibility for compensation or benefits as a retired employee, a director or
Chairman of the Board of Directors.

     Section 12. Notices. All notices and other communications hereunder shall
be in writing and shall be deemed to have been duly given when personally
delivered or when placed

                            FIRST RESTATEMENT OF THE
                 FIFTH AMENDED AND RESTATED LINE OF CREDIT NOTE

$7,000,000                                       As of November 12, 1999
                                                 Restated on March 24, 2000

     FOR VALUE RECEIVED, BLONDER TONGUE LABORATORIES, INC., a Delaware
corporation (the "Borrower"), hereby promises to pay to the order of FIRST UNION
NATIONAL BANK (the "Bank") on the Termination Date the principal amount of SEVEN
MILLION DOLLARS ($7,000,000) or, if less, the aggregate outstanding principal
under the Line of Credit extended under the Fifth Amended and Restated Loan
Agreement dated November 12, 1999 by and between the Borrower and the Bank as
amended by the First Amendment and Waiver to the Fifth Amended and Restated Loan
Agreement dated the date hereof as may be further amended, modified or restated
from time to time (the "Loan Agreement"). Terms capitalized but not defined
herein shall have the meanings given to them respectively in the Loan Agreement.
Reference is made to the Loan Agreement for a statement of the terms and
conditions under which the loans evidenced hereby have been made, secured, and
may be prepaid or accelerated. This Note amends and restates and replaces (but
does not discharge) the obligations of the Borrower under the Fifth Amended and
Restated Line of Credit Note dated as of November 12, 1999, as such note has
been amended, modified and/or extended.

     Until maturity (whether by acceleration or otherwise) interest shall accrue
on the outstanding principal balance hereof at the rate set forth in the Loan
Agreement. Interest shall be calculated on the basis of a 360-day year, counting
the actual number of days elapsed. Subsequent to maturity or the occurrence of
any Event of Default, and continuing after entry of any judgment against the
Borrower with respect to the obligations evidenced by this Note, interest shall
accrue at an annual rate which shall be two percent (2%) above the rate of
interest otherwise payable hereunder. Accrued interest shall be payable monthly
on the first day of each month commencing with the month immediately following
date hereof and if not paid when due, shall be added to the principal. All
amounts payable by the Borrower to the Bank hereunder shall be paid directly to
the Bank at 190 River Road, Summit, New Jersey 07901 (or at such other address
of which the Bank shall give notice to the Borrower in accordance with the Loan
Agreement) in immediately available funds.

     The Borrower hereby waives the requirements of demand, presentment,
protest, notice of protest and dishonor and all other demands or notices of any
kind in connection with the delivery, acceptance, performance, default, dishonor
or enforcement of this Note. The internal law of the State of New Jersey shall
govern the construction, interpretation and enforcement of this Note.

     This note amends, restates, replaces and continues (but not a novation or
repayment of) the Fifth Amended and Restated Line of Credit Note dated November
12, 1999.

     IN WITNESS WHEREOF, and intending to be legally bound hereby, the Borrower
has caused this Note to be executed by its duly authorized officer as of the day
and year first above written.

                                           BLONDER TONGUE LABORATORIES, INC.
