CERTIFICATE OF AMENDMENT AND RESTATEMENT

                                      OF

                          ARTICLES OF INCORPORATION


          Richard B. Gordinier and Jeffrey A. Wahba certify that:

          1.   They are the President and Secretary, respectively, of Henry 
Company, a California corporation.

          2.   The Articles of Incorporation of the Corporation are amended 
and restated to read in their entirety as follows:


                          ARTICLES OF INCORPORATION

                                      OF

                                HENRY COMPANY

          ONE:        The name of this corporation is:

                                 Henry Company

          TWO:  The purpose of the corporation is to engage in any lawful act 
or activity for which a corporation may be organized under the General 
Corporation Law of California, other than the banking business, the trust 
company business or the practice of a profession permitted to be incorporated 
by the California Corporations Code.

          THREE:  The number of shares of stock which the Corporation is 
authorized to issue is One Million (1,000,000) shares of Common Stock, no par 
value (the "Common Stock"), and Thirty Thousand (30,000) shares of Class A 
Common Stock, no par value (the "Class A Common Stock").  The number of 
shares of Preferred Stock which this Corporation is authorized to issue is 
100,000 shares, without par value.

          The Preferred Stock may be issued from time to time in one or more 
series.  The rights, preferences, privileges and restrictions granted to and 
imposed upon the first such series, designated Series A Convertible Preferred 
Stock, of which the 

                                      


Corporation is to issue Twenty-Two Thousand Five Hundred (22,500) shares, are 
set forth below.  The Board of Directors of the Corporation is expressly 
authorized to provide for the issue of all or any of the remaining shares of 
Preferred Stock in one or more series, and to fix the number of shares and to 
determine or alter for each such series, such voting powers, full or limited, 
or no voting powers, and such designations, preferences and relative, 
participating, optional or other rights and such qualifications, limitations 
or restrictions thereof, as shall be stated and expressed in the resolution 
or resolutions adopted by the Board of Directors providing for the issue of 
such shares, and as may be permitted by the General Corporation Law of the 
State of California.  The Board of Directors is authorized to decrease the 
number of shares of any series subsequent to the issuance of shares of that 
series, but not below the number of shares of that series then outstanding.  
In case the number of shares of any series shall be so decreased, the shares 
constituting such decrease shall resume the status they had prior to the 
adoption of the resolution originally fixing the number of shares of such 
series.

          The relative rights, powers, preferences and restrictions granted 
to the Common Stock, Class A Common Stock and Series A Convertible Preferred 
Stock Classes is as follows:

                                 COMMON STOCK

          On all matters upon which shareholders are entitled or permitted to 
vote, every holder of Common Stock shall be entitled to one (1) vote for each 
share of Common Stock standing in his name on the transfer books of the 
Corporation and every holder of Class A Common Stock shall be entitled to 
thirty-five (35) votes for each share of Common Stock standing in his name on 
the transfer books of the Corporation.  Except as otherwise may be required 
by law, the holders of Common Stock and Class A Common Stock shall vote 
together as a single class.  Except as provided in this Article THREE, the 
Common Stock and the Class A Common Stock shall have the same rights and 
privileges and shall rank equally, share ratably and be identical in all 
respects as to all matters.

                     SERIES A CONVERTIBLE PREFERRED STOCK

          1.  DESIGNATION.  The first series of Preferred Stock is 
designated the Series A Convertible Preferred Stock and the number of shares 
of such series is 22,500.  The Series A Convertible Preferred Stock shall, 
with respect to rights on liquidation, winding up and dissolution, rank prior 
to the Corporation's Common Stock, Class A Common Stock and all other series 
or classes of the Corporation's equity securities now or hereafter 
authorized, issued or outstanding.

                                      -2-


          2.  DIVIDEND RIGHTS.  

               (a)  The holders of the Series A Convertible Preferred Stock 
shall be entitled to receive, on an as-converted basis, any dividends which 
are declared on the Corporation's Class A Common Stock or Common Stock, when, 
as and if declared by the Board of Directors, out of the assets of the 
Corporation which are legally available therefor.

               (b)  Dividends shall not accrue or accumulate on any share of 
Series A Preferred Stock, except to the extent they are declared but unpaid. 
Accumulation of declared but unpaid dividends shall bear no interest.

          3.  VOTING RIGHTS.  The holder of each share of Series A 
Convertible Preferred Stock shall have the right to one vote for each share 
of Common Stock into which such share of Series A Convertible Preferred Stock 
could be converted at the record date for determination of the shareholders 
entitled to vote on any matters, or, if no such record date is established, 
at the date such vote is taken or any written consent of shareholders is 
solicited (with any fractional share determined on an aggregate conversion 
basis being rounded to the nearest whole share), and with respect to such 
vote, such holder shall have full voting rights and powers equal to the 
voting rights and powers of the holders of Common Stock, and shall be 
entitled to notice of any shareholders' meeting in accordance with the bylaws 
of the Corporation, and shall be entitled to vote, together with holders of 
Common Stock, with respect to any question upon which holders of Common Stock 
have the right to vote.

          Without the consent of a majority of the outstanding shares of the 
Series A Convertible Preferred Stock (so long as any such shares are 
outstanding), the Corporation shall not effect any amendment, repeal or 
alteration of the Corporation's Articles of Incorporation (or any provision 
thereof) which would adversely affect any of the specific rights, powers or 
privileges of the Series A Convertible Preferred Stock set forth herein.

          4.  CONVERSION RIGHTS.  The holders of the Series A Convertible 
Preferred Stock shall have conversion rights as follows (the "Conversion 
Rights"):

               (a)  RIGHT TO CONVERT.  Each share of Series A Convertible 
Preferred Stock shall be convertible, at the option of the holder thereof, 
without payment of additional consideration, at any time after the date of 
issuance of such share, at the office of the Corporation or any transfer 
agent for such stock, into fully-paid and nonassessable shares of Common 
Stock.  

                                      -3-


               (b)  CONVERSION PRICE.  The Series A Convertible Preferred 
Stock shall be convertible into the number of shares of Common Stock which 
result from dividing the Conversion Price (as hereinafter defined) in effect 
at the time of conversion into $1.00.  The price at which shares of Common 
Stock shall be deliverable upon conversion of Series A Convertible Preferred 
Stock (the "Conversion Price") shall initially be $1.00 per share of Common 
Stock.  Such initial Conversion Price shall be subject to adjustment as 
hereinafter provided.

               (c)  AUTOMATIC CONVERSION.  Each share of Series A Convertible 
Preferred Stock shall automatically be converted into shares of Common Stock 
at the then effective Conversion Price, in the event of the closing of a firm 
commitment underwritten public offering pursuant to an effective registration 
statement under the Securities Act of 1933, as amended, covering the offer 
and sale of any equity securities of the Corporation (whether for the account 
of the Corporation or for the account of one or more shareholders of the 
Corporation) having aggregate proceeds (prior to expenses for underwriters 
discount or other expenses) to the Corporation and/or selling shareholders in 
excess of Ten Million Dollars ($10,000,000). 

               Upon the occurrence of an automatic conversion, the 
outstanding shares of Series A Convertible Preferred Stock shall be converted 
automatically without further action by the holders of said shares and 
whether or not the certificates representing said shares are surrendered to 
the Corporation or its transfer agent; provided, however, the Corporation 
shall not be obligated to issue certificates evidencing the shares of Common 
Stock unless certificates evidencing the Series A Convertible Preferred Stock 
are either delivered to the Corporation or any transfer agent as hereinafter 
provided, or the holder notifies the Corporation that said certificate or 
certificates have been lost, stolen or destroyed and executes an agreement 
satisfactory to the Corporation, indemnifying  the Corporation against any 
loss incurred by it in connection therewith.  In the event of an underwritten 
public offering, the person(s) entitled to receive the Common Stock issuable 
upon conversion of the Series A Convertible Preferred Stock shall not be 
deemed to have converted such stock until immediately prior to the closing of 
such sale of equity securities (the "Offering Conversion Date").  
               
               (d)  MECHANICS OF VOLUNTARY CONVERSION.  Before any holder of 
the Series A Convertible Preferred Stock shall be entitled to convert the 
same into full shares of Common Stock, he shall surrender the certificate or 
certificates therefore, duly endorsed, at the office of the Corporation or of 
any transfer agent for such stock, and shall give written notice to the 
Corporation at such office that he elects to convert the same.  The 
Corporation shall, as soon as practicable thereafter, issue and deliver to 
such holder, at such office and in his name as shown on such surrendered 
certificate or certificates, a certificate or certificates for the number of 
shares of Common Stock into 

                                      -4-


which such converted shares of stock were convertible on the Conversion Date 
(as hereinafter defined).  Such conversion shall be deemed to have been made 
immediately prior to the close of business on the date of such surrender of 
the shares of the Series A Convertible Preferred Stock (the "Conversion 
Date").  The person or persons entitled to receive the shares of Common Stock 
issuable upon such conversion shall be treated for all purposes as the record 
holder or holders of such shares of Common Stock as of the Conversion Date.

               (e)  FRACTIONAL SHARES.  No fractional shares of Common Stock 
or scrip shall be issued upon conversion of shares of Series A Convertible 
Preferred Stock.  If more than one share of Series A Convertible Preferred 
Stock shall be surrendered for conversion at any one time by the same holder, 
the number of full shares of Common Stock issuable upon conversion thereof 
shall be computed on the basis of the aggregate number of shares of Series A 
Convertible Preferred Stock so surrendered.  Instead of any fractional shares 
of Common Stock which would otherwise be issuable upon conversion of any 
shares of Series A Convertible Preferred Stock, the Corporation shall pay a 
cash adjustment in respect of such fractional interest in an amount equal to 
the fair market value of such fraction as of the date of Conversion (as 
determined in good faith by the Board of Directors).

               (f)  CONVERSION PRICE ADJUSTMENTS.  The Conversion Price shall 
be subject to adjustment from time to time as follows:

                    (i)   STOCK DIVIDENDS, SUBDIVISIONS, RECLASSIFICATIONS 
OR COMBINATIONS.  If the Corporation shall (i) declare a dividend or make a 
distribution on its Common Stocks in shares of its Common Stock, (ii) 
subdivide or reclassify the outstanding shares of Common Stock into a greater 
number of shares, or (iii) combine or reclassify the outstanding Common Stock 
into a smaller number of shares, the Conversion Price in effect at the time 
of the record date for such dividend or distribution or the effective date of 
such subdivision, combination or reclassification shall be proportionately 
adjusted so that the holder of any shares of Series A Convertible Preferred 
Stock surrendered for conversion after such date shall be entitled to receive 
the number of shares of Common Stock which he would have owned or been 
entitled to receive had such Series A Convertible Preferred Stock been 
converted immediately prior to such date. Successive adjustments in the 
Conversion Price shall be made whenever any event specified above shall occur.

                    (ii)   CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE. 
In case of any consolidation with or merger of the Corporation with or into 
another corporation, or in case of any sale, lease or conveyance to another 
corporation of the assets of the Corporation as an entirety or substantially 
as an entirety, each share of Series A Convertible Preferred Stock shall 
after the date of such consolidation, merger, sale, lease or conveyance be 
convertible into the number of shares of stock or other securities or 
property (including cash) to which the Common Stock issuable (at the time of 
such consolidation, merger, 

                                      -5-


sale, lease or conveyance) upon conversion of such share of Series A 
Convertible Preferred Stock would have been entitled upon such consolidation, 
merger, sale, lease or conveyance; and in any such case, if necessary, the 
provisions set forth herein with respect to the rights and interests 
thereafter of the holders of the shares of Series A Convertible Preferred 
Stock shall be appropriately adjusted so as to be applicable, as nearly as 
may reasonably be, to any shares of stock or other securities or property 
thereafter deliverable on the conversion of the shares of Series A 
Convertible Preferred Stock.

                    (iii)   ROUNDING OF CALCULATIONS; MINIMUM ADJUSTMENT.  
All calculations under this subparagraph (f) shall be made to the nearest 
cent or to the nearest one hundredth (1/100th) of a share, as the case may 
be.  Any provision of this subparagraph (f) to the contrary notwithstanding, 
no adjustment in the Conversion Price shall be made if the amount of such 
adjustment would be less than $0.05, but any such amount shall be carried 
forward and an adjustment with respect thereto shall be made at the time of 
and together with any subsequent adjustment which, together with such amount 
and any other amount or amounts so carried forward, shall aggregate $0.05 or 
more.

               (g)  STATEMENT REGARDING ADJUSTMENTS.  Whenever the Conversion 
Price shall be adjusted as provided in subparagraph 4(f), the Corporation 
shall forthwith file, at the office of any transfer agent for the Series A 
Convertible Preferred Stock and at the principal office of the Corporation, a 
statement showing in detail the facts requiring such adjustment and the 
Conversion Price that shall be in effect after such adjustment, and the 
Corporation shall also cause a copy of such statement to be sent by mail, 
first class postage prepaid, to each holder of shares of Series A Convertible 
Preferred Stock at its address appearing on the Corporation's records.  Each 
such statement shall be signed by the Corporation's independent public 
accountants, if applicable.  Where appropriate, such copy may be given in 
advance and may be included as part of a notice required to be mailed under 
the provisions of subparagraph 4(h).

               (h)  NOTICE TO HOLDERS.  In the event the Corporation shall 
propose to take any action of the type described in clause (f) which would 
result in an adjustment in the Conversion Price), the Corporation shall give 
notice to each holder of shares of Series A Convertible Preferred Stock, in 
the manner set forth in subparagraph 4(g), which notice shall specify the 
record date, if any, with respect to any such action and the approximate date 
on which such action is to take place.  Such notice shall also set forth such 
facts with respect thereto as shall be reasonably necessary to indicate the 
effect of such action (to the extent such effect may be known at the date of 
such notice) 

                                      -6-


on the Conversion Price and the number, kind or class of shares or other 
securities or property which shall be deliverable upon conversion of shares 
of Series A Convertible Preferred Stock.  In the case of any action which 
would require the fixing of a record date, such notice shall be given at 
least ten (10) days prior to the date so fixed, and in case of all other 
action, such notice shall be given at least fifteen (15) days prior to the 
taking of such proposed action. Failure to give such notice, or any defect 
therein, shall not affect the legality or validity of any such action.

               (i)  TREASURY STOCK.  For the purposes of this paragraph 4, 
the sale or other disposition of Common Stock theretofore held in the 
Corporation's treasury shall be deemed to be an issuance thereof.

               (j)  COSTS.  The Corporation shall pay all documentary, stamp, 
transfer or other transactional taxes attributable to the issuance or 
delivery of shares of Common Stock upon conversion of any shares of Series A 
Convertible Preferred Stock; provided that the Corporation shall not be 
required to pay any taxes which may be payable in respect of any transfer 
involved in the issuance or delivery of any certificate for such shares in a 
name other than that of the holder of the shares of Series A Convertible 
Preferred Stock in respect of which such shares are being issued.

               (k)  RESERVATION OF SHARES.  The Corporation shall reserve at 
all times so long as any shares of Series A Convertible Preferred Stock 
remain outstanding, free from preemptive rights, out of its treasury stock 
(if applicable) or its authorized but unissued shares of Common Stock, or 
both, solely for the purpose of effecting the conversion of the shares of 
Series A Convertible Preferred Stock, sufficient shares of Common Stock to 
provide for the conversion of all outstanding shares of Series A Convertible 
Preferred Stock.

               (l)  APPROVALS.  If any shares of Common Stock to be reserved 
for the purpose of conversion of shares of Series A Convertible Preferred 
Stock require registration with or approval of any governmental authority 
under any federal or state law before such shares may be validly issued or 
delivered upon conversion, then the Corporation will in good faith and as 
expeditiously as possible endeavor to secure such registration or approval, 
as the case may be. If, and so long as, any Common Stock into which the 
shares of Series A Convertible Preferred Stock are then convertible is listed 
on any national securities exchange, the Corporation will, if permitted by 
the rules of such exchange, list and keep listed on such exchange, upon 
official notice of issuance, all shares of such Common Stock issuable upon 
conversion.

               (m)  VALID ISSUANCE.  All shares of Common Stock which may be 
issued upon conversion of the shares of Series A Convertible Preferred Stock 
will upon issuance by the Corporation be duly and validly issued, fully paid 
and nonassessable 

                                      -7-


and free from all taxes, liens and charges with respect to the issuance 
thereof, and the Corporation shall take no action which will cause a contrary 
result (including without limitation, any action which would cause the 
Conversion Price to be less than the par value, if any, of the Common Stock).

          5.   PREFERENCE ON LIQUIDATION.  

               (a)  In the event of any liquidation, dissolution, involuntary 
or voluntary corporate reorganization under the federal bankruptcy laws or 
similar state laws, or winding up of the Corporation, the holders of shares 
of the Series A Convertible Preferred Stock then outstanding shall be 
entitled to be paid out of the assets and surplus funds of the Corporation 
available for distribution to its shareholders, and before any payment shall 
be made to the holders of any shares of Common Stock, an amount equal to 
$63.955 per share (or an aggregate of One Million Four Hundred Thirty-nine 
Thousand ($1,439,000) with respect to Twenty-two Thousand Five Hundred 
(22,500) shares)  plus any declared and unpaid dividends thereon to the date 
fixed for distribution.  If upon any such liquidation, dissolution, 
bankruptcy or winding up of the Corporation the assets and surplus funds of 
the Corporation available for distribution to its shareholders shall be 
insufficient to pay the holders of the Series A Convertible Preferred Stock 
the full amounts to which they are entitled, the holders of the Series A 
Convertible Preferred Stock shall share ratably in the distribution of such 
assets and surplus funds in proportion to the full preferential amounts to 
which each such holder is otherwise entitled.

               (b)  In the event payments provided for in subparagraph (a) 
above shall have been made, the holders of the Common Stock shall be entitled 
to share PRO RATA in all remaining assets and surplus funds of the 
Corporation available for distribution to its shareholders; PROVIDED, 
HOWEVER, that in the event of a voluntary corporate reorganization under the 
federal bankruptcy law or similar state laws or a voluntary winding up, the 
holders of the Preferred Stock and the Common Stock shall be entitled to 
share PRO RATA on a per share basis (treating each share of Preferred Stock 
as if converted into Common Stock) in all remaining assets and surplus funds 
of the Corporation available for distribution to its shareholders.

               (c)  The merger or consolidation of the Corporation into or 
with another corporation or other entity or any other corporate 
reorganization in which the Corporation shall not be the continuing or 
surviving entity of such consolidation, merger or reorganization, the sale of 
all or substantially all the assets of the Corporation, or a transaction or 
series of related transactions by the Corporation in which in excess of fifty 
percent (50%) of the Corporation's voting power is transferred, shall not be 
deemed to be a liquidation, dissolution or winding up of the Corporation.

                                      -8-


          FOUR:     The liability of the directors of the Corporation for 
monetary damages shall be eliminated to the fullest extent permissible under 
California law.

          FIVE:     The Corporation is authorized to indemnify the directors and
officers of the Corporation to the fullest extent permissible under California
law.

          SIX:      The amendment and restatement of the Articles of 
Incorporation as herein set forth has been duly approved by the Board of 
Directors.

          The amendment and restatement herein set forth herein have been 
duly approved by the required vote of shareholders in accordance with Section 
903 of the California General Corporation Law.  The total number of 
outstanding shares of each class entitled to vote with respect to the 
amendment was One Hundred Ninety-four Thousand (194,000) shares of Common 
Stock and Six Thousand (6,000) shares of Class A Common Stock.  The number of 
shares of each class voting in favor of the amendment equal or exceeded the 
vote required; the percentage vote required for each class entitled to vote 
was more than fifty percent (50%).
