     This Custodial Agreement (this "Custodial Agreement"), dated as of April 
22, 1998, is entered into by and among Henry Company, a California 
corporation ("Buyer"), the Sellers (as defined in the Agreement referred to 
in the Recital A below) of Monsey Products Co., a Pennsylvania corporation 
("Company"), Edward P. Mooney, as Sellers' representative (the 
"Representative") and PNC Bank, National Association, as custodian (the 
"Custodian").

                                      RECITALS:

     A.   Buyer and the Sellers have entered into that certain Stock Purchase 
Agreement dated February 22, 1998 (the "Agreement"); and

     B.   Pursuant to the Agreement, Buyer will acquire all of the stock of 
the Company; and

     C.   Pursuant to the Agreement, Buyer and the Sellers have agreed that, 
at a closing held thereunder (the "Closing"), Buyer will cause to be 
deposited into a custodial account (the "Account") Two Million Dollars 
($2,000,000) to secure the indemnification provided for Sellers 
(collectively, the "Indemnitee") as specified in Section 10 of the Agreement 
and each claim thereunder (a "Claim"); and

     D.   It is a condition to the consummation of the transactions 
contemplated by the Agreement that at or prior to the Closing, this Custodial 
Agreement be entered into by the parties hereto; and

     E.   A copy of the Agreement has been delivered to the Custodian, and 
the Custodian is willing to act as Custodian hereunder.  It is understood 
that the Custodian is not a party to the Agreement and will execute its 
duties in accordance with the Custodial Agreement.

     NOW, THEREFORE, in consideration of the premises and of the mutual 
covenants and agreements hereinafter set forth, and of other good and 
valuable consideration, the parties hereto agree as follows:

                                 TERMS AND CONDITIONS

     1.   ESCROW.  At the Closing, Buyer shall cause to be delivered to the 
Custodian an aggregate of Two Million Dollars ($2,000,000) (the "Assets").  
The Custodian hereby acknowledges receipt of the Assets and agrees to hold 
the same in escrow pursuant to the terms of this Custodial Agreement.  The 
Custodian shall open an account for the benefit of the Sellers, to be 
entitled the Henry Co./Monsey Products Custodial A/C (the "Account"), into 
which the Assets shall be deposited.  The Custodian shall hold the Assets, 
not as an agent of any

                                           -1-


of the Sellers, but rather as a pledgeholder with respect to the pledge of 
the Assets pursuant to this Custodial Agreement.

          The Custodian will hold the Assets in the name of the Custodian or 
in the name of its nominee, or, as to securities eligible or to be held by 
the Depository Trust Company or other depository, in the name of its nominee.

          2.   CLAIMS AND DISTRIBUTIONS. 

               a.   The Assets held in the Account and pledged to the 
Indemnitee shall serve to secure the indemnification provided for in Section 
10.2 of the Agreement.  There shall be no indemnity hereunder with respect to 
any notice of claim (a "Notice of Claim") delivered by Buyer to the 
Representative more than two (2) years from and after the date of the 
Closing.  Any Notice of Claim shall be deemed effective only when delivered 
to both the Representative and the Custodian.

               b.   Any Notice of Claim filed by Buyer to Custodian and 
Representative shall specify in reasonable detail the facts and circumstances 
of the claim; the basis on which the Sellers are believed to have liability 
therefor; and the estimated amount of loss alleged to have been suffered or 
liability incurred by Buyer as a result thereof.  Such estimates of loss or 
liability (while not binding on Buyer) shall be prepared by Buyer on a 
reasoned basis consistent with the facts and circumstances out of which the 
claim arose.

               c.   If the Custodian is furnished by the Indemnitee with a 
Notice of Claim against the Sellers, and no notice of objection to such claim 
(a "Notice of Objection") is furnished by the Representative to the Custodian 
and Buyer within thirty (30) days of the date of receipt of the Notice of 
Claim by the Custodian (which the Custodian may assume to be the same as the 
date of receipt of the Notice of Claim by the Representative), the Claim will 
be deemed to be non-disputed (the "Non-Disputed Claims");

               d.   If the Custodian is furnished by Representative with a 
Notice of Objection within thirty (30) days of the date of receipt of the 
Notice of Claim by the Custodian, the Claim will be deemed disputed (the 
"Disputed Claim");

               e.   Assets may be released from the Account as follows:
 
                                            -2-


                    (1)  On the first anniversary date of the Closing, the 
Custodian shall release from the Account and deliver to the Representative 
One Million Dollars ($1,000,000), less the amount of any unresolved Notices 
of Claim and less the Assets that have been applied by the Custodian to the 
satisfaction of Claims to date.

                    (2)  On the second anniversary date of the Closing, the 
Custodian shall  release from the Account and shall deliver to the 
Representative all of the Assets held hereunder, less the amount of any 
unresolved Notices of Claim and less the Assets that have been applied by 
Custodian to the satisfaction of claims, and such Assets shall thereupon 
cease to be subject to the Pledge and this Custodial Agreement.
     
               (3)  As to Non-Disputed Claims, the Custodian shall distribute 
to Buyer the amount of the Claim.

               (4)  As to Disputed Claims resolved by Buyer and      
     Representative, the Custodian shall, upon receipt of joint written      
     instructions which appear on their face to be executed by the      
     Representative and Buyer, distribute the Assets in accordance with such  
     instructions.

               (5)  As to Disputed or non-resolved Claims, the Custodian shall,
     upon receipt of a document which appears on its face to be a written order
     from an arbitrator declaring that the Assets are to be distributed, or upon
     receipt of a document which appears on its face to be a written court order
     or judgment declaring that the Assets are to be distributed, distribute the
     Assets in accordance with such order or judgment.

               (6)  Upon receipt of written instructions from the Buyer
     certifying that (i) Buyer has suffered Damages in respect of Taxes for
     which it is to be indemnified under the Agreement, and (ii) that such Taxes
     are due or otherwise payable as a result of a decision to pay the Taxes and
     sue for refund, accompanied by a copy of a Notice of Deficiency from the
     Internal Revenue Service or a notice of proposed assessment from any state
     taxing agency requiring payment of taxes with respect to a period on or
     prior to the date of this Agreement (a "Tax Statement"), the Custodian
     shall distribute to Buyer the amount specified in the Tax Statement.

          In the event a controversy arises between the Representative and
Buyer under this Agreement with respect to the distribution of the Assets under

                                             -3-


this Agreement, the Custodian shall not be required to resolve such 
controversy or take any action but shall be entitled to await resolution of 
the controversy by joint written instructions from the Representative and 
Buyer.  In the event the Sellers' Representative and Buyer are unable to 
resolve such controversy, the Custodian shall have the right to join the 
Sellers, the Representative and Buyer in an action for interpleader to 
resolve such controversy.

     3.   SERVICES; INVESTMENT OF ASSETS.  The Custodian is hereby authorized 
to perform the following services in connection with the Assets in the 
Account:

          a.   So long as the Assets are held by the Custodian, they shall be 
invested by the Custodian as specifically directed in writing by (i) 
Representative, in obligations of or guaranteed by the United States of 
America or any state or local subdivision thereof to the extent such 
obligation is insured, in commercial paper obligations rated A-1 or P-1 or 
better by Moody's Investors Service, Inc. or Standard & Poor's Ratings 
Service, respectively, or in certificates of deposit, bank repurchase 
agreements or banker's acceptances of commercial banks with capital exceeding 
$500,000,000 (Five Hundred Million Dollars), or (ii) as otherwise directed by 
Representative or his designee with the prior written consent of Buyer, which 
consent shall not be unreasonably withhold, conditioned or delayed.  Absent 
written direction, the Assets will be invested in the Provident Institutional 
T-Fund Dollar Shares Portfolio, a AAAm-rated fund.  Neither the Custodian, 
Buyer nor the Representative shall be liable or responsible for any loss 
resulting from any investment or reinvestment made pursuant to this Section 3.
The Assets shall be increased from time to time by any and all interest 
accrued and paid thereon (after payment of expenses incurred in connection 
with the investment, reinvestment or sale thereof) pursuant to this Section 3.

          b.   On a monthly basis until the termination of this Agreement, 
the Custodian shall deliver to Buyer and the Representative a report 
outlining (i) the principal amount of the Account as of such date and the 
interest earned thereon during the preceding monthly period and (ii) a copy 
of or a description of each notice pursuant to which payments from the 
Account have been made, and a description of all other payments made from 
this Account, during the preceding one-year period, and all pending notices 
as of such date;

          c.   All interest earned pursuant to this Section 3 shall be deemed 
as income of the Sellers and not the Account or Buyer for federal, state and 
local income tax purposes, and the Sellers shall pay any federal, state and 
local income taxes attributable to such income.  Prior to April 15, 1999 and 
April 15, 2000, as the case may be, the Custodian shall distribute to each of 
the Sellers its

                                             -4-


proportionate share of any interest or other earnings on the Account earned 
during the prior taxable year.

     4.   THE REPRESENTATIVE.

          a.   For so long as this Custodial Agreement is in effect, with 
regard to any claims for indemnification, the Sellers shall act through the 
Representative, who shall be deemed authorized to act on behalf of all of the 
Sellers in the manner set forth in this paragraph 5.  As used herein, the 
term "Representative" shall include the plural when more than one 
Representative has been appointed to act herein by the Sellers.  The Sellers 
have appointed Edward P. Mooney as their initial Representative.

          b.   A Representative may resign at any time effective upon giving 
written notice to each of the parties hereto.  In the event of the 
resignation, refusal or inability to act of any Representative, the Sellers 
who owned a majority of the shares of the Company's Common Stock before the 
Closing may by written election appoint any number of successor 
Representatives and shall so appoint a successor if the Representative in 
question was the only Representative in office.  The Representative shall 
promptly notify Buyer and the Custodian in writing of the resignation of any 
Representative and of the appointment of any successor Representative.

          c.   The Custodian may rely conclusively upon any written 
instruction or action of the Representative.  The Custodian may rely 
conclusively on the authority of a Representative designated herein or by the 
Sellers, as herein provided, until the Custodian receives a written 
instruction naming one or more other or additional Representatives to succeed 
to that position in the place of or in addition to any other Representative, 
which instruction shall be signed by Sellers who owned a majority of the 
Company common stock before the Merger.

          d.   The Representative may take any action which it deems 
appropriate to take with respect to any Notice of Claim received by it 
hereunder.

          e.   The Representative may at any time and without regard to 
whether or not proceedings for the resolution or determination thereof have 
commenced, agree upon, resolve, send Notices of Objection, settle, or 
compromise any claim against Assets held hereunder, whether or not specified 
in a Notice of Claim, in the sole and absolute discretion of the 
Representative.

                                         -5-


          f.   The Representative may, in its sole and absolute discretion, 
pursue, elect not to pursue, or terminate the pursuit of any claim or issue 
involving the Assets held hereunder, whether or not evidenced by a Notice of 
Claim, including the conduct of arbitration of and litigation of third party 
claims, as provided herein and in the Agreement.

          g.   Under no circumstances shall the Representative be liable to 
any Seller for any act it may take in its capacity as Representative, or for 
the failure to take any action, or for the actions of any other 
Representative or shareholder, or for any damage, loss or expense suffered or 
incurred resulting from the exercise of the Representative's sole and 
absolute discretion in acting hereunder, except only for acts of gross 
negligence or willful misconduct.

          h.   The Representative shall be and hereby is authorized to retain 
counsel, accountants, or other professional assistants to assist in 
determining the validity of claims or in otherwise acting hereunder as a 
Representative.

          i.   The Representative shall not be liable for any expense 
incurred on behalf of the Sellers or any of them in protesting, analyzing, 
resisting, arbitrating, litigating, negotiating with respect to, or defending 
any claim made against the Assets, or for any amounts otherwise expended in 
acting hereunder.

          j.   On demand by the Representative, each Seller shall contribute 
all sums demanded to pay the fees and expense incurred by the Representative 
on behalf of the Sellers in acting hereunder. 

          k.   The Representative shall keep the Sellers reasonably informed 
of actions taken by it in acting hereunder.

          l.   This Agreement shall be binding on and shall inure to the 
benefit of the heirs, legatees, personal representatives, successors and 
assigns of the respective Sellers.

     5.   CONCERNING THE CUSTODIAN.

          a.   Under no circumstances shall the Custodian be liable to Buyer, 
the Representative or any Seller for any act it may take in its capacity as 
Custodian, or for the failure to take any action, or for any error of 
judgment, or for any damage, loss or expenses suffered or incurred resulting 
therefrom or in acting hereunder, except only for acts of gross negligence or 
willful misconduct.
 
                                          -6-



          b.   Buyer hereby agrees to indemnify and hold the Custodian 
harmless in respect of any and all losses, costs, expenses, liabilities, 
judgments, assessments, penalties, damages, deficiencies, suits, actions, 
proceedings, or demands, and reasonable attorneys' fees and expenses incident 
thereto resulting from any action or refusal to act by the Custodian taken in 
accordance with the instructions of Buyer.  The Custodian shall promptly 
notify Buyer of any asserted liability for which the Custodian would be 
entitled to indemnification by Buyer, and Buyer and its legal representatives 
shall have, at Buyer's election, a right to compromise or defend any such 
matter involving asserted liability, through counsel of its own choosing, at 
its expense; provided, however, that Buyer shall indemnify the Custodian 
against any damage resulting from the failure to pay any claims on all such 
litigation pending.  In the event Buyer undertakes to compromise and defend 
any such liability, Buyer shall notify the Custodian in writing promptly of 
its intention to do so, and the Custodian shall cooperate with Buyer and its 
counsel in the compromising of or the defending against any such liabilities 
or claims, at the expense of Buyer.  The indemnification shall survive the 
resignation or termination of the Custodian.

          c.   The Sellers, jointly and severally, hereby agree to indemnify 
and hold the Custodian harmless in respect of any and all losses, costs, 
expenses, liabilities, judgments, assessments, penalties, damages, 
deficiencies, suits, actions, proceedings or demands, and reasonable 
attorneys' fees and expenses incident thereto resulting from any action or 
refusal to act by the Custodian in accordance with the instructions of any 
Seller or Representative.  The Custodian shall promptly notify the 
Representative of any asserted liability for which the Custodian would be 
entitled to indemnification by the Sellers, and the Sellers and their legal 
representatives shall have, at the election of the Representative, a right to 
compromise or defend any such matter involving asserted liability, through 
counsel of their own choosing, at their expense; provided, however, that the 
Sellers shall indemnify the Custodian against any damage resulting from the 
failure to pay any claims on all such litigation pending.  In the event the 
Sellers undertake to compromise or defend any such liability, the 
Representative shall notify the Custodian in writing promptly of their 
intention to do so, and the Custodian shall cooperate with the Sellers and 
their counsel in the compromising of or the defending against any such 
liabilities or claims, at the expense of the Sellers. The indemnification 
shall survive the resignation or termination of the Custodian.

          d.   The Escrow Agent may resign at any time by giving thirty (30) 
days written notice of such resignation to Buyer and Representative.  If no 
successor Escrow Agent has been named at the expiration of the thirty (30) day

                                         -7-


period, the Escrow Agent shall have no further obligation hereunder except to 
hold the Escrow Fund as a depository.  Upon notification by Buyer of the 
appointment of the successor, the Escrow Agent shall promptly deliver the 
Escrow Fund and all materials in its possession relating to the Escrow Fund 
to such successor, and the duties of the resigning Escrow Agent shall 
thereupon in all respects terminate, and it shall be released and discharged 
from all further obligations hereunder.

               Similarly, the Escrow Agent may be discharged from its duties 
as Escrow Agent under this Agreement upon thirty (30) days written notice 
from Buyer and Representative and upon payment of any and all fees due to 
Escrow Agent.  In such event, the Escrow Agent shall be entitled to rely on 
instructions from Buyer as to the disposition and delivery of the Escrow Fund.

     6.   FEES OF THE CUSTODIAN.  The fees and expenses of the Custodian, 
including counsel fees, for acting hereunder shall be paid by Sellers and 
Buyer, as set forth thereto in Exhibit A.  The Custodian shall have a lien on 
the Assets to secure payment of fees and expenses.

     7.   MISCELLANEOUS.

          a.   SUCCESSORS.  This Agreement shall be binding upon and shall 
inure to the benefit of the parties herein and their respective heirs, 
executors, successors and assigns.

shall supersede all previous negotiations, commitments and writings with 
respect to the subject matter hereof or thereof.  This Custodial Agreement 
may not be released, discharged, abandoned, changed or modified in any 
manner, except by an instrument in writing signed on behalf of each of the 
parties hereto by their duly authorized officers or representatives.  The 
failure of any party hereto to enforce at any time any provision of this 
Custodial Agreement shall in no way be construed to be a waiver of such 
provision, nor in any way to affect the validity of this Custodial Agreement 
or any part thereof or the right of any party thereafter to enforce each and 
every such provision.  No waiver of any breach of this Custodial Agreement 
shall be held to be a waiver of any other or subsequent breach.
