                             SECURED PROMISSORY NOTE


$2,000,000                                                         June 30, 1997


     FOR VALUE RECEIVED, the undersigned, Cadmus Corporation, a Massachusetts
corporation ("Payor"), hereby unconditionally promises to pay to the order of
ELXSI, a California corporation ("Payee"), the principal sum of TWO MILLION AND
00/100 DOLLARS ($2,000,000) on June 30, 1999 (the "Maturity Date"), or such
earlier date as may otherwise be provided for herein, plus interest at the rate
and on the date provided for herein.

     This Promissory Note (this "Note") has been issued to evidence and set
forth the terms of a $2,000,000 loan (the "Loan") made on June 30, 1997 by the
Payee to the Payor. The Loan was made in order to finance the purchase by the
Payor of 6,517 shares of Series AAA 5% Cumulative Redeemable Preferred Stock,
par value $1.00 per share, of Azimuth Corporation (the "Stock"). As part of the
terms of the Loan, the Payor has agreed: (i) to pay to the Payee a 5% (or
$100,000) closing fee (the "Loan Fee") ; and (ii) to pay or reimburse the Payee
for all of its fees and expenses in connection with its borrowing of such Loan
funds for on-lending to the Payor (the "Loan Expenses").

SECTION 1. INTEREST, PAYMENTS AND PREPAYMENTS.

     1.1.  The unpaid principal balance of this Note shall bear interest at a
rate per annum equal to fifteen percent (15%).

     1.2.  Interest hereunder shall be due payable quarterly in arrears, on the
last day of March, June, September and December, commencing with September 30,
1997.

     1.3.  Payments and prepayments of principal and interest on this Note shall
be made in lawful money of the United States of America by wire or bank
transfer, or as otherwise designated by Payee, in immediately available funds to
an account designated in writing by Payee.

     1.4.  If the date on which any payment is required to be made pursuant to
the provisions of this Note occurs on a Saturday, Sunday or legal holiday
observed in the State of New York, such payment shall be due and payable on the
immediately succeeding date which is not a Saturday, Sunday or legal holiday so
observed.

     1.5.  The principal and interest on this Note may be voluntarily prepaid,
in whole or in part, at any time and from time to time, provided that any
principal amount so prepaid shall be accompanied by payment of the accrued but
unpaid interest thereon. Prepayments shall be applied first to interest and then
to principal.

     1.6.  Nothing contained in this Note shall be deemed to establish or
require the payment of a rate of interest in excess of the maximum rate legally
enforceable. If the rate of interest called for under this Note at any time
exceeds the maximum rate legally enforceable, or if any charges payable pursuant
hereto are, according to applicable laws, construed to be interest which has the
effect of causing the interest hereunder to exceed the maximum rate legally
enforceable, the rate of interest and/or charges required to be paid hereunder
shall be automatically reduced so that the interest hereunder does not exceed
the maximum rate legally enforceable. If such interest rate and/or charges are
so reduced and thereafter the maximum rate legally enforceable is increased, the
rate of interest and/or fees required to be paid hereunder shall be
automatically increased to the maximum rate legally enforceable, which in no
event shall exceed the rate otherwise provided for in this Note.

SECTION 2. PLEDGE OF STOCK.

     2.1.  In order to secure the prompt and complete payment and performance
when due of all of the obligations of the Payor hereunder, the Payor DOES HEREBY
pledge to the Payee, and grant to the Payee and continuing first priority
security interest in, all of Payor's right, title and interest in, to and under
the following (collectively, the "Collateral"): (i) the Stock; (ii) any and all
dividends and distributions, sinking fund and redemption payments and
liquidation payments (in each case, whether in the form of cash, securities or
other property) paid on, under or with respect to any of the Stock or other
Collateral; (iii) any consideration received from the sale, exchange, lease or
other disposition of Stock or other Collateral; (iv) any and all other or
additional stock or other securities or property (including cash) paid or
distributed in respect of any Stock or other Collateral by way of stock-split,
spin-off, split-up, reclassification, combination of shares or similar
rearrangement; and (v) any other item constituting products or proceeds of the
Stock or other Collateral within the meaning of the Uniform Commercial Code of
the State of New York.

     2.2.  The Payor covenants and agrees that it will, at his own cost and
expense, defend its title to the Collateral and the Payee's right, title and
interest therein granted hereunder, against the claims and demands of all
persons and entities whomsoever.

     2.3.  Following, and during the continuance of, any Event of Default (as
hereinafter defined), the Payee irrevocably makes, constitutes, and appoints the
Payee (and all officers, employees, or agents designated by Payee) as the
Payor's true and lawful agent, proxy and attorney-in-fact, with full power of
substitution, for the purpose of taking any action and to executing any document
or instrument which the Payee may deem necessary or advisable to accomplish the
purposes of this Note, including without limitation, to: (i) transfer record
title to the Stock and other Collateral to the Payee (or its nominee or
assignee); and (ii) vote the Stock and other Collateral.

any, provided with respect thereto, or Payor defaults in the observance or
performance of any other term, covenant, agreement, condition, undertaking or
provision contained in any agreement or instrument evidencing or securing or
related to any such indebtedness for borrowed money or guarantee, if the effect
thereof is to cause, or permit the holder or holders thereof (or a trustee or
trustees on behalf of such holder or holders) to cause, and such holder or
holders have caused, such indebtedness for money borrowed or guarantee to become
due prior to its stated maturity; PROVIDED that the aggregate amount of all
indebtedness affected as aforesaid shall equal or exceed $2,000; or

     3.3.  (i) Payor shall commence any case, proceeding or other action (A)

relating to bankruptcy, insolvency, reorganization or relief of debtors, seeking
to have an order for relief entered with respect to it, or seeking to adjudicate
it a bankrupt or insolvent, or seeking reorganization, arrangement, adjustment,
winding-up, liquidation, dissolution, composition or other relief with respect
to it or its debts, or (B) seeking appointment of a receiver, trustee, custodian
or other similar official for it or for all or any substantial part of its
assets, or shall make a formal or informal general assignment for the benefit of
its creditors; or (ii) there shall be commenced against Payor any case,

<PAGE>

upon the occurrence and during the continuance of any such event (an "Event of
Default"), Payee (unless there shall have occurred an Event of Default under
Section 3.3, in which case the unpaid balance of this Note shall automatically
become due and payable) may, by written notice to Payor, declare this Note due
and payable, whereupon the same shall become due and payable, without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived.

SECTION 4. MISCELLANEOUS.

     4.1.  All notices, requests, demands or other communications to or upon
Payor or Payee shall be deemed to have been given or made when deposited in the

Orlando, Florida 32811, and to Payee at the same address. No other method of
giving notice is hereby precluded.

     4.2.  No failure or delay on the part of the Payee in exercising any right,
power or privilege hereunder, and no course of dealing between Payor and Payee
shall operate as a waiver thereof nor shall any single or partial exercise of
any right, power or privilege hereunder preclude the simultaneous or later
exercise of any other right, power or privilege. The rights and remedies herein
expressly provided are cumulative and not exclusive of any rights or remedies
which the Payee would otherwise have. No notice to or demand on Payor in any
case shall entitle the Payee to any other or further notice or demand in similar

of this Note, if mutilated, Payor will make and deliver a new Note of like tenor
in lieu of such lost, stolen, destroyed or mutilated Note.

     4.5.  This Note shall be binding upon Payor and Payee and their respective
successors and permitted assigns. This Note, and the rights and obligations
hereunder, may not be assigned or delegated by Payor without the prior written
consent of Payee.
