                           CERTIFICATE OF DESIGNATION
                                       OF
                            SERIES E PREFERRED STOCK
                                       OF
                              DIPLOMAT CORPORATION

        Pursuant to Section 151 of the Delaware General Corporation Law,
Diplomat Corporation (the "Corporation"), a corporation organized and existing
under and by virtue of the provisions of the Delaware General Corporation Law
that pursuant to authority conferred upon the Board of Directors of the
Corporation (the "Board") by the Certificate of Incorporation of the
Corporation, the Board, by a Unanimous Written Consent dated September 23, 1997,
adopted the following resolution authorizing the creation and issuance of a
series of 3,480 shares of Series E Preferred Stock, (the "Series E Preferred
Stock" or the "Series"), which resolution is as follows:

             RESOLVED, that pursuant to authority expressly granted to and
vested in the Board of Directors by the Certificate of Incorporation, as
amended, of the Corporation, the Board hereby creates a series of 3,480 shares
of Series E Preferred Stock, of the Corporation and authorizes the issuance
thereof, and hereby fixes the designation thereof, preferences and relative,
participating, optional and other special limitations or restrictions thereon
(in addition to the designations, preferences and relative, participating and
other special rights, and the qualifications, limitations or restrictions
thereof, set forth in the Certificate of Incorporation, as amended, of the
Corporation, which are applicable to the preferred stock of all series, if any)
as follows:

               1.   DESIGNATION.  The  shares  of the  Series  shares  shall be
designated "Series E Preferred Stock", and the number of shares constituting the
Series shall be 3,480.

               2.   DIVIDENDS. Holders of the Series E Preferred Stock (the
"Holders") shall be entitled to an annual cumulative dividend of six percent
(6%) of the Liquidation Value of the Series E Preferred Stock for a period of
three years commencing on the date of issuance, and twelve percent (12%)
thereafter, all dividends being payable annually in arrears. Dividends will be
payable in cash or, at the option of the Company, in Common Stock. Dividends
payable for any period less than a full year, will be computed on the basis of a
360 day year with equal months of 30 days.

               3.     LIQUIDATION.

                      (a)    Liquidation  Preference.  Upon any liquidation, 
dissolution, or winding up of the Corporation, whether voluntary or involuntary,
and after provision for the payment of creditors, the 




<PAGE>

Holders shall be entitled to be paid an amount equal to $1000.00 per share
("Liquidation Value") of Series E Preferred Stock held, before any distribution
or payment is made upon any shares of Common Stock and any other series of stock
junior to the Series E Preferred Stock but subject to the prior preferences of
any series or class of stock of the Corporation senior to the Series E Preferred
Stock.

                      (b)    Ratable  Distribution.  If upon any liquidation, 
dissolution or winding up of the Corporation, the net assets of the Corporation
to be distributed among the Holders shall be insufficient to permit payment in
full to the Holders of such Series E Preferred Stock, then all remaining net
assets of the Corporation after the provision for the payment of the
Corporation's debts and distribution to any senior stockholders shall be
distributed ratably in proportion to the full amounts to which they would
otherwise be entitled to receive among the Holders.

                      (c)    Corporate  Changes.  The sale, lease or exchange of
all or substantially all of the Corporation's assets or the merger or
consolidation of the Corporation which results in the holders of Common Stock of
the Corporation receiving in exchange for such Common Stock cash, notes,
debentures or other evidences of indebtedness or obligations to pay cash, or
preferred stock of the surviving entity which ranks on a parity with or senior
to the Series E Preferred Stock as to dividends or upon liquidation, dissolution
or winding-up shall be deemed to be a liquidation, dissolution or winding up of
the affairs of the Corporation within the meaning of this Section 3(c). In the
case of mergers or consolidations of the Corporation where holders of Common
Stock of the Corporation receive, in exchange for such Common Stock, common
stock or preferred stock in the surviving entity (whether or not the surviving
entity is the Corporation) of such merger or consolidation, or common stock or
preferred stock of another entity (in either case, such preferred stock to be
received in exchange for common stock is herein referred to as "Exchanged
Preferred Stock"), which is junior as to dividends and upon liquidation,
dissolution or winding up to the Series E Preferred Stock, the merger agreement
or consolidation agreement shall expressly provide that the Series E Preferred
Stock shall become preferred stock of such surviving entity or other entity, as
the case may be, with the same annual dividend rate and equivalent rights to the
rights set forth herein; provided however that if the Exchanged Preferred Stock
is to be mandatorily redeemed in whole or in part through the operation of a
sinking fund or otherwise the merger or consolidation agreement shall expressly
provide that, or other provisions shall be made so that, all shares of the
Series E Preferred Stock shall be mandatorily redeemed prior to the first
mandatory redemption of the Exchanged Preferred Stock; and provided further,
that in the event the Corporation or an affiliate of the 

                                       2

<PAGE>

Corporation optionally redeems or otherwise acquires any or all of the then
outstanding shares of Exchanged Preferred Stock, the Corporation shall redeem
all shares of Series E Preferred Stock. In the event of a merger or
consolidation of the Corporation where the consideration received by the holders

of common stock consists of two or more types of the consideration set forth
above, the holders of the Series E Preferred Stock shall be entitled to receive
either cash or securities based upon the foregoing in the same proportion as the
holders of common stock of the Corporation are receiving cash or debt
securities, or equity securities in the surviving entity or other entity.

             4. REDEMPTION. The Company may at any time it may lawfully do so,
redeem in whole or in part the Series E Preferred Stock by paying in cash
therefore a sum equal to $1,000 per share of Series E Preferred Stock (as
adjusted for any stock dividends, combinations or splits with respect to such
shares) plus all unpaid dividends on such shares ("Redemption Price").

             5. VOTING RIGHTS. Except as required under Delaware law, the
Holders shall not have any right or power to vote on any question or in any
proceeding or to be represented at or to receive notice of any proceeding or
meeting of the stockholders.

               6. CONVERSION RIGHTS. The Series E Preferred Stock shall not be
convertible into Common Stock.

               7. NO PREEMPTIVE RIGHTS. No holders of Series E Preferred Stock,
whether now or hereafter authorized, shall, as such holder, have any preemptive
right whatsoever to purchase, subscribe for or otherwise acquire, stock of any
class of the Corporation nor of any security convertible into, nor of any
warrant, option or right to purchase, subscribe for or otherwise acquire, stock
of any class of the Corporation, whether now or hereafter authorized.

               8. EXCLUSION OF OTHER RIGHTS. Except as may otherwise be required
by law, the shares of Series E Preferred Stock shall not have any preferences or
relative, participating, optional or other special rights, other than those
specifically set forth in this resolution (as such resolution may be amended
from time to time) and in the Corporation's Certificate of Incorporation. The
Shares of Series E Preferred Stock shall have no preemptive or subscription
rights.

               9. HEADINGS OF SUBDIVISIONS. The headings of the various
subdivisions hereof are for convenience of reference only and shall not affect
the interpretation of any of the provisions hereof.

               10. SEVERABILITY OF PROVISIONS. If any right, preference or
limitation of the Preferred Stock set forth in this Certificate (as such
Certificate may be amended from time to time) is invalid, unlawful or incapable
of being enforced by reason of any rule of law or public policy, all other
rights, preferences and limitations set forth in this Certificate (as so
amended) which can be given effect without the invalid, unlawful or
unenforceable right, preference or limitation shall, nevertheless, remain in
full force and effect, and no right, preference or limitation herein set forth
shall be deemed dependent upon any other such right, preference or limitation
unless so expressed herein.


               11. STATUS OF REACQUIRED SHARES. Shares of Series E Preferred
Stock which have been issued and reacquired in any manner shall (upon compliance
with any applicable provisions of the laws of the State of Delaware) have the
status of authorized and unissued shares of Series E Preferred Stock issuable in
series undesignated as to series and may be redesignated and reissued.
