    5.    In  October  1992,  the  Company  acquired
          Tigon
          Corporation  (Tigon)  which  was  accounted  for  as  a
          purchase.   In the second quarter of fiscal  1994,  the
          Company made the final adjustment to the purchase price
          allocation  which  had  the effect  of  increasing  the
          purchase  reserve $2.2 million, goodwill  $1.3
          million and current deferred income tax asset $.9
          million.

Financial Condition and Results of Operations

NET REVENUES

      Net revenues increased to $75.1 million in the
second quarter  of  fiscal  1994, a 24 percent
increase  from  net revenues  of $60.7 million in the
second quarter of  fiscal 1993.   In the first six
months of fiscal 1994 net revenues increased  to
$143.8 million as compared to $109.3  million in  the
corresponding period of fiscal 1993,  representing
growth  of  32  percent.  Systems revenues  in  the
second quarter  of fiscal 1994 were $53.5 million, an
increase  of 15 percent from $46.4 million in the same
quarter of fiscal 1993,  and for the first six months
of fiscal 1994  systems revenues  were  $102.2
million, an increase of  19  percent compared to $85.7
million in the first six months of fiscal 1993.             
The  growth  in
systems  revenues  was  primarily
attributable  to  the sale of systems to new  and
existing customers  and  the  sale of upgrades,
expansions  and  new features, including the Company's
fax products, to existing customers  in the Customer
Premise Equipment (CPE)  sector. CPE  revenues  for
both the second quarter  and  first  six months  of
fiscal 1994 increased over the same periods  in fiscal
1993 in both the domestic and international markets,
although  growth was more significant internationally
than domestically.  Voice Information Service (VIS)
revenues  in total  for both the second quarter and
first six months  of fiscal 1994 increased over the
same periods in fiscal 1993; however,    international
VIS   revenues,   which    were exceptionally high in
the second quarter of fiscal 1993 due to two large
orders from customers, decreased in the second quarter
of  fiscal  1994 compared  to  the  second  fiscal
quarter  of  1993.   Revenue in future  quarters
could  be affected  by the extent and timing of new
orders  from  VIS providers and such orders are
typically significant in size and, therefore, could
impact the revenue volume and mix  in any given
quarter.

Service  and  support  revenues in the  second
quarter  of fiscal 1994 increased to $21.6 million, or
50 percent  from $14.4  million in the same quarter of
fiscal 1993, and  for the  first  six months of fiscal
1994 service  and  support revenues increased to $41.6
million, or 76 percent compared to  $23.6  million in
the first six months of fiscal  1993. In  addition,
service and support revenues continue to grow as  a
percentage of total net revenues and accounted for 29
percent  of net revenues for the second quarter  and
first six months of fiscal 1994 as compared to 24
percent and  22 percent  for  the second quarter and
first  six  months  of fiscal  1993,  respectively.
The increase in  service  and support  revenues  is
primarily due to  the  inclusion  of service revenues
from Tigon which have been included  since its
acquisition on October 21, 1992.  In addition, service
and  support revenues grew in the second quarter and
first six  months of fiscal 1994 as compared to the
same  periods of  the  prior  year  as a result of the
Company's  larger installed base of customers and
systems.

Item 2.   Management's Discussion and Analysis of
Financial Condition and Results of Operations (Continued)
                              
COST OF SALES

      As  a percentage of net revenues, total cost of
sales increased to 41 percent in the second quarter
and first six months of fiscal 1994 compared to 38
percent and 37 percent in  the second quarter and
first six months of fiscal 1993, respectively.  The
majority of this increase is a result of the  higher
percentage of total revenues  attributable  to
service.  The service revenue increase is primarily
due  to the  inclusion  of  Tigon which has a
traditional  service industry  cost  structure  of
lower  gross  margins  as  a percentage  of  revenue.
Cost of  systems  sales  were  33 percent  of net
systems revenues in the second quarter  and first six
months of fiscal 1994.  Cost of system sales were 32
percent and 31 percent in the second quarter and
first six months of fiscal 1993, respectively.  The
increases  as a  percentage of net systems revenues
in fiscal  1994  were due                       to
reduced  list  prices  of  certain  products  and
increased  sales  promotions offered in fiscal  1994
which were  offset by the effects of reduced
manufacturing  costs and a favorable change in
product mix evidenced by the fact that  sales  volume
of the Company's  higher  end,  higher margin
systems increased at a higher rate than lower  end,
lower margin systems.  Cost of service and support
revenues were  60  percent and 61 percent of net
service and support revenues  in  the second quarter
and first  six  months  of fiscal  1994,
respectively.  Cost of service  and  support revenues
were  57  percent and 59 percent  in  the  second
quarter  and first six months of fiscal 1993,
respectively. The  increases  in  the second quarter
and  the  first  six months  of  fiscal  1994
compared  to  fiscal  1993   were primarily  due  to
the inclusion of Tigon  revenues,  which continue  to
become  a higher percentage  of  consolidated
revenue.   Tigon  cost  of  sales  have  increased
as   a percentage  of net revenues in the second
quarter  and  the first  six  months  of  fiscal 1994
compared  to  the  same periods  in fiscal 1993 as a
result of a change in  service product           mix
with  an  increase  in  revenue                  from
the
residential   market which traditionally  has  lower
gross
margins  than  the  commercial market.   On  a
quarter-toquarter  basis, the channel and product mix
of  sales  can fluctuate  significantly.  Such
fluctuations  can  have  a positive  or  negative
impact on operating margins.                    These
fluctuations are difficult to predict.


RESEARCH AND DEVELOPMENT

      Research and development expenses were $11.3
million in  the  second quarter of fiscal 1994, an
increase  of  47 percent  over  the  $7.7  million
expended  in  the  second quarter of fiscal 1993.
For the first six months of fiscal 1994  and  1993,
research and development costs were  $22.4 million
and  $15.1 million, respectively, representing  an
increase of 48 percent in fiscal 1994.  As a
percentage  of net  revenues,  research and
development expenses  were  15 percent  and  13
percent in the second quarters  of  fiscal 1994  and
1993, respectively, and 16 percent and 14 percent for the  first  six
months  of  fiscal  1994  and  1993,
respectively.   The  increase in research  and
development expenses  is  due  to the Company's
increased  spending  on projects  to  meet customer
commitments such as  clustering
and  the adaptation of existing products and
technology for international markets, as well as the
continued  commitment to  the  development  of new
products and  enhancements  to existing  products.
The Company believes  that  additional research  and
development expenses  will  be  required  to maintain
market  position and expects that  expenses  will
increase  in  absolute  terms  and  could  increase
as   a percentage of net revenues.

Financial Condition and Results of Operations (Continued)
                              
SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

      Selling,  general  and administrative  expenses
were $25.7  million in the second quarter of fiscal
1994,  a  14 percent increase over the second quarter
of fiscal 1993  of $22.5  million.  For the first six
months of  fiscal  1994, these  expenses  were  $50.2
million,  an  increase  of  17 percent over the $43.0
million expended in the same  period of   fiscal
1993.   Selling,  general  and  administrative
expenses decreased as a percentage of net revenues in
both the  second quarter and six months ended
December 31, 1994, decreasing  from 37 percent and 39
percent  in  the  second quarter  and first six
months of fiscal 1993, respectively, to  34  percent
and 35 percent in the corresponding periods of
fiscal 1994.  The increase in absolute dollars
resulted from the Company's continuing efforts to
develop and manage its  organization, train new and
existing personnel and the commitment      of
resources   to   support   international
opportunities.   In  addition,  the  inclusion  of
Tigon's selling,  general and administrative
expenses,  which  were included for only
approximately two and one-half months  in the  first
six months of fiscal 1993, contributed  to  the
increase.   ^Two expense items contributed to the
increase in  absolute  terms of selling, general and
administrative expenses  in  the  second quarter of
fiscal  1994. First,
approximately   $750,000  of  non-recurring   expense
was incurred  related to the departure of the former
President and Chief Executive Officer from the
Company.  Robert Cohn, a  founder  of  the  Company
and its  President  and  Chief Executive Officer from
1982 to 1990, was appointed to  fill this   position.
The  second  item,  approximating          an
incremental $500,000, was incurred in the second
quarter of fiscal  1994  for legal expenses related
to ongoing  patent litigation.             The
Company estimates legal expenses  related
to ongoing patent litigation will be approximately
$600,000 in  the  last  six  months  of fiscal       1994.   The  Company
believes    that    additional   selling,    general
and administrative  expenses will be required to
maintain  its competitiveposition,  including
expanded  international
sales  activities,  and expects that  these  expenses
will increase  in  absolute  terms  and  could
increase  as   a percentage of net revenues.

INTEREST AND OTHER INCOME, NET

      Interest and other income, net for the second
quarter of  fiscal 1994 decreased $795,000 from the
same period  of fiscal 1993 and decreased in the
first six months of fiscal 1994  by $1.1 million from
the same period last year.   The decrease  in  the
second quarter and first  six  months  of fiscal 1994
was primarily attributable to smaller net gains on
sales  of  short-term investments  and  lower
interest
income  due  to  lower interest rates and  lower
cash  and equivalent  and short-term investment
balances,  offset  by the  effect of the Compass
acquisition expenses which  were incurred in the
first quarter of fiscal 1993.

Item 2.   Management's Discussion and Analysis of
Financial Condition and Results of Operations (Continued)
                              
INCOME TAXES

     The Company's effective tax rate was 28 percent
and 23 percent  in  the  second quarter and first
six  months  of fiscal 1994, respectively, as
compared to 34 percent and 33 percent in the
corresponding periods of fiscal 1993.   This decrease
was  primarily attributable  to  the  retroactive
reinstatement  of the U.S. research and development
credit for the fiscal year ended June 30, 1993, which
amounted  to $200,000  and  $1.1  million for the
three-  and  six-month periods  ended December 31,
1993, respectively.   Prior  to any  effects  of the
proposed merger discussed in  "Factors That  May
Effect Future Results of Operations", the  effect of
the  reinstatement is expected to be  a  three
percent reduction  to  the effective tax rate for the
1994  fiscal year  and the Company expects its
effective tax rate to  be approximately  32  percent
for the  remaining  quarters  of fiscal 1994.

FACTORS THAT MAY EFFECT FUTURE RESULTS OF OPERATIONS

     The Company believes that in the future its
results of operations  could  be affected by factors
such  as  market acceptance  of  new products and
upgrades,  growth  in  the worldwide  voice
processing market,  the  success  of  the Company's
customers in marketing voice information products and
adverse changes in general economic conditions in
any of  the countries in which the Company does
business. The
Company's  ability  to  develop  and  market
products  and services  that successfully adapt to
current  market  needs may  also have an impact on
the results of operations.,   A portion of future
revenues will come from new products  and services.
The Company cannot determine the ultimate effect that
new  products  and services will  have  on  revenues,
earnings or stock price.

      Because  of  the factors noted herein, the
Company's future   earnings  and  stock  price  may
be  subject                  to
significant volatility, particularly on a quarterly
basis. Past  financial  performance should  not  be
considered  a reliable  indicator  of  future
performance  and  investors should  not use
historical trends to anticipate results  or trends
in  future periods.  Any shortfall  in  revenue  or
earnings from the levels anticipated by securities
analysts could  have  an  immediate and significant
effect  on  the trading  price of the Company's
common stock in  any  given period.  Additionally, the
Company may not learn  of  such
shortfalls  until  late in a fiscal  quarter,  which
could result in an even more immediate and adverse
effect on  the trading price of the Company's common
stock.  Further,  the Company  participates  in a
highly dynamic  industry  which often  results in
volatility of the Company's common  stock price.

     In January 1994, the Company entered into a
definitive agreement  to  merge  with VMX, Inc.
(VMX).   VMX  provides integrated messaging and call
processing systems,  software and  services  that
combine voice,  data  and  images  for business
communications, internationally.  The terms of the
merger  provide  for  the issuance  of  one  share
of  the Company's common stock for every five shares
of outstanding VMX  common  stock.
Therefore, the  Company  would  issue
approximately  5.3  million  shares  of  common
stock   in accordance  with  this agreement.  The
Company  intends  to account for this transaction
using the pooling of interests method.
The  Company expects the merger to  be  completed
late  in  April  1994, which is subject to
regulatory  and stockholder approval.

Item 2.   Management's Discussion and Analysis of
Financial Condition and Results of Operations (Continued)
                              
      Because  Octel and VMX intend to continue to
support the      product   lines  of  both  companies
following the
completion  of the merger, the Company does not
anticipate that the announcement of the merger will
have a significant effect  on  sales  of  its
systems  in  the  near  future. However,  there  can
be no assurance that distributors  and potential
customers  will continue  their  current  buying
patterns  without regard to the announced merger,
and  any significant  delay  or reduction in orders
could  have  an adverse  effect  on  the Company's
near-term  business  and results  of  operations.   
The Company  anticipates  that total  non-recurring
transaction costs associated with  the merger during
the third and fourth fiscal quarters of  1994 will
total  approximately  $3.4  million.   The  Company's
estimated   portion  of  the  merger   related
costs   is approximately $2.2 million.  In the event
that  the  merger is  not  completed  for certain
reasons  specified  in  the agreement with VMX
governing the merger, a portion of these expenses
could  be  offset by payments  from  VMX  or  the
Company could be obligated to make expense
reimbursement or damages  payments to VMX.  In
addition, the Company expects to record a
restructuring reserve in the accounting records in
the  fourth  quarter of fiscal 1994  related  to
costs associated  with  the  worldwide  integration
of  the  two organizations following the completion
of the merger.

LIQUIDITY AND CAPITAL RESOURCES

      The  Company's  cash and equivalents  and
short-term investments  in  the  first  six  months
of  fiscal   1994 decreased  $16.5 million from June
30, 1993. The  primary
uses  of  cash during the first six months of  fiscal
1994 were  the repurchase of common stock for
approximately $5.1 million  under the Company's stock
repurchase  plan,  which aims  to  increase return to
investors as compared  to  the return  which  would
be  made by investing  the  cash  and generating
interest  at  the  current  low                rates,   and
investment  in  property and equipment  of  $19.3
million. Cash flows from operations resulted in a net
source of cash of $13.3 million in the first six
months of fiscal 1994.

      During  fiscal 1993, the Company invested $16
million in  the  purchase  of  land  and  the
development  of  the Company's new corporate offices
on that land.  In the first six  months of fiscal
1994, the Company spent approximately
$9.8  million  on this project and the Company
expects  to spend          approximately $16.3
million during the remainder  of
fiscal  1994  and $3 million in fiscal 1995  in
connection with  the  construction  of  the
Company's  new  corporate offices.   The Company also
expects to purchase  additional equipment  and  make
certain leasehold improvements  during the remainder
of fiscal 1994.  The Company anticipates that its
property  and  equipment investments  will
eventually result  in reduced operating expenses,
greater efficiencies and increased flexibility for
the Company.

     The Company anticipates that cash flow from

operations and existing cash and equivalents and

short-term investment balances  will  be  adequate to

meet  the  Company's  cash requirements  through  the

end  of  fiscal  1994.    After completion  of  the

proposed merger discussed  in  "Factors That  May

Effect Future Results of Operations", the Company

believes  that cash flow from operations and existing

cash and equivalents and short-term investment

balances will  be adequate  to  meet the combined

Company's cash requirements through the end of fiscal

1994.

                 AGREEMENT AND PLAN OF REORGANIZATION
                                   

     This AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is
made and entered into as of January 29, 1994 among Octel Communica
tions Corporation, a Delaware corporation ("Parent"), Octel Acqui
sition Corporation, a Delaware corporation ("Merger Sub") and a wholly-
owned subsidiary of Parent, and VMX, Inc., a Delaware corporation (the
"Company").


                               RECITALS

     A.     The Boards of Directors of each of the Company, Parent and
Merger Sub believe it is in the best interests of each company and
their respective stockholders that the Company and Merger Sub combine
into a single company through the merger of Merger Sub with and into
the Company (the "Merger") and, in furtherance thereof, have approved
the Merger.

     B.     Pursuant to the Merger, among other things, the
outstanding shares of Common Stock of the Company ("Company Capital
Stock") shall be converted into shares of Common Stock of Parent
("Parent Common Stock") at the rate determined herein.

     C.     The Company, Parent and Merger Sub desire to make certain
representations and warranties and other agreements in connection with
the Merger.

     D.     The parties intend, by executing this Agreement, to adopt
a plan of reorganization within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended (the "Code").

     NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable
consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties agree as follows:


                               ARTICLE I
                                   
                              THE MERGER

     1.1    The Merger.  At the Effective Time (as defined in
Section 1.2) and subject to and upon the terms and conditions of this
Agreement, and a Merger Agreement (the "Merger Agreement") and the
applicable provisions of the Delaware General Corporations Law
("Delaware Law"), Merger Sub shall be merged with and into the
Company, the separate corporate existence of Merger Sub shall cease
and the Company shall continue as the surviving corporation.  The
Company as the surviving corporation after the Merger is hereinafter
sometimes referred to as the "Surviving Corporation."

     1.2    Effective Time  As promptly as practicable after the
satisfaction or waiver of the conditions set forth in Article VI, the
parties hereto shall cause the Merger to be consummated by filing the
Merger Agreement with the Secretary of State of the State of Delaware,
in accordance with the relevant provisions of Delaware Law (the time
of such filing being the "Effective Time"). The Closing of the
transaction contemplated hereby (the "Closing") shall take place at
1:00 p.m. at the offices of Wilson, Sonsini, Goodrich & Rosati,
Professional Corporation on April 27, 1994, or at such other time,
date and location as the parties hereto agree (the "Closing Date").

     1.3    Effect of the Merger  At the Effective Time, the effect of
the Merger shall be as provided in this Agreement, the Merger
Agreement and the applicable provisions of Delaware Law. Without
limiting the generality of the foregoing, and subject thereto, at the
Effective Time all the property, rights, privileges, powers and
franchises of the Company and Merger Sub shall vest in the Surviving
Corporation, and all debts, liabilities and duties of the Company and
Merger Sub shall become the debts, liabilities and duties of the
Surviving Corporation.

     1.4    Certificate of Incorporation; Bylaws.

            (a)  Unless otherwise determined by Parent prior to the
Effective Time, at the Effective Time the Certificate of Incorporation
of Merger Sub, as in effect immediately prior to the Effective Time,
shall be the Certificate of Incorporation of the Surviving Corporation
until thereafter amended as provided by law and such Certificate of
Incorporation; provided, however, that Article I of the Certificate of
Incorporation of the Surviving Corporation shall be amended to read as
follows:  "The name of the corporation is VMX, Inc."

            (b)  The Bylaws of Merger Sub, as in effect immediately
prior to the Effective Time, shall be the Bylaws of the Surviving
Corporation until thereafter amended.

     1.5    Directors and Officers   The directors of Merger Sub shall
be the initial directors of the Surviving Corporation, until their
respective successors are duly elected or appointed and qualified.
The officers of the Merger Sub shall be the initial officers of the
Surviving Corporation, in each case until their respective successors
are duly elected or appointed and qualified.

     1.6    Effect on Capital Stock.  At the Effective Time, by virtue
of the Merger and without any action on the part of Merger Sub, the
Company or the holders of any of the following securities:

     (a)    Conversion of Company Capital Stock.  Each share of Common
Stock, $0.05 par value, of the Company (the "Company

DMP2HY.R4(5P3)
01/29/94                        -2-

Capital Stock") issued and outstanding immediately prior to the
Effective Time (other than any shares of Company Capital Stock to be
canceled pursuant to Section 1.6(b) will be canceled and extinguished
and be converted automatically into the right to receive .20 of a
share of Common Stock, $0.001 par value, of the Parent (the "Parent
Common Stock"), (the "Exchange Ratio").

            (b)  Cancellation of Parent-Owned Stock.  Each share
of Company Capital Stock owned by Merger Sub, Parent or any direct or
indirect wholly owned subsidiary of Parent or of the Company
immediately prior to the Effective Time shall be canceled and
extinguished without any conversion thereof.

            (c)  Stock Options.  At the Effective Time, all options to
purchase Company Capital Stock then outstanding under the Company's
1981 ECS Stock Option Plan, 1983 Stock Option Plan, Employee Stock
Purchase Plan, 1986 Stock Option Plan, VMX Inc./OPCOM 1982 Stock
Option Plan, 1989 Stock Option Plan, 1989 Restated Nonstatutory Stock
Option Plan and Nonstatutory Stock Option Plan and any other plan
pursuant to which options set forth in Section 2.2 have been issued
(the "Company Stock Option Plans") shall be assumed by Parent in
accordance with Section 5.14 hereof.

            (d)  Capital Stock of Merger Sub.  Each share of Common
Stock, $.001 par value, of Merger Sub issued and outstanding imme
diately prior to the Effective Time shall be converted into and
exchanged for one validly issued, fully paid and nonassessable share
of Common Stock, no par value, of the Surviving Corporation. Each
stock certificate of Merger Sub evidencing ownership of any such
shares shall continue to evidence ownership of such shares of capital
stock of the Surviving Corporation.

            (e)  Adjustments to Exchange Ratio.  The Exchange Ratio
shall be adjusted to reflect fully the effect of any stock split,
reverse split, stock dividend (including any dividend or distribution
of securities convertible into Parent Common Stock or Company Capital
Stock), reorganization, recapitalization or other like change with
respect to Parent Common Stock or Company Capital Stock occurring
after the date hereof and prior to the Effective Time.

            (f)  Fractional Shares.  No fraction of a share of Parent
Common Stock will be issued, but in lieu thereof each holder of shares
of Company Capital Stock who would otherwise be entitled to a fraction
of a share of Parent Common Stock (after aggregating all fractional
shares of Parent Common Stock to be received by such holder) shall
receive from Parent an amount of cash (rounded to the nearest whole
cent) equal to the product of (i) such fraction, multiplied by
(ii) the average closing price of a share of Parent Common Stock for
the ten most recent days that Parent Common Stock has traded ending on
the trading day immediately prior to the Effective Time, as reported
on the NASDAQ National Market System.


DMP2HY.R4(5P3)
01/29/94                        -3-
     1.7    Surrender of Certificates.

            (a)  Exchange Agent.  Chemical Trust Company of California
shall act as exchange agent (the "Exchange Agent") in the Merger.

            (b)  Parent to Provide Common Stock.  Promptly after the
Effective Time, Parent shall make available to the Exchange Agent for
exchange in accordance with this Article I, through such reasonable
procedures as Parent may adopt, the shares of Parent Common Stock
issuable pursuant to Section 1.6 in exchange for outstanding shares of
Company Capital Stock.

            (c)  Exchange Procedures.  Promptly after the Effective
Time, the Surviving Corporation shall cause to be mailed to each
holder of record of a certificate or certificates (the "Certificates")
which immediately prior to the Effective Time represented outstanding
shares of Company Capital Stock whose shares were converted into the
right to receive shares of Parent Common Stock pursuant to
Section 1.6, (i) a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the
Certificates shall pass, only upon delivery of the Certificates to the
Exchange Agent and shall be in such form and have such other
provisions as Parent may reasonably specify) and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for
certificates representing shares of Parent Common Stock.  Upon
surrender of a Certificate for cancellation to the Exchange Agent or
to such other agent or agents as may be appointed by Parent, together
with such letter of transmittal, duly completed and validly executed
in accordance with the instructions thereto, the holder of such
Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of whole shares of Parent Common
Stock and payment in lieu of fractional shares which such holder has
the right to receive pursuant to Section 1.6, and the Certificate so
surrendered shall forthwith be canceled.  Until so surrendered, each
outstanding certificate that, prior to the Effective Time, represented
shares of Company Capital Stock will be deemed from and after the
Effective Time, for all corporate purposes, other than the payment of
dividends, to evidence the ownership of the number of full shares of
Parent Common Stock into which such shares of Company Capital Stock
shall have been so converted and the right to receive an amount in
cash in lieu of the issuance of any fractional shares in accordance
with Section 1.6.

            (d)  Distributions With Respect to Unexchanged Shares.
No dividends or other distributions declared or made after the date of
this Agreement with respect to Parent Common Stock with a record date
after the Effective Time will be paid to the holder of any
unsurrendered Certificate with respect to the shares of Parent Common
Stock represented thereby until the holder of record of such


DMP2HY.R4(5P3)
01/29/94                        -4-

Certificate shall surrender such Certificate.  Subject to applicable
law, following surrender of any such Certificate, there shall be paid
to the record holder of the certificates representing whole shares of
Parent Common Stock issued in exchange therefor, without interest, at
the time of such surrender, the amount of dividends or other
distributions with a record date after the Effective Time theretofore
paid with respect to such whole shares of Parent Common Stock.

            (e)  Transfers of Ownership.  If any certificate for
shares of Parent Common Stock is to be issued in a name other than
that in which the certificate surrendered in exchange therefor is
registered, it will be a condition of the issuance thereof that the
certificate so surrendered will be properly endorsed and otherwise in
proper form for transfer and that the person requesting such exchange
will have paid to Parent or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for
shares of Parent Common Stock in any name other than that of the
registered holder of the certificate surrendered, or established to
the satisfaction of Parent or any agent designated by it that such tax
has been paid or is not payable.

            (f)  No Liability.  Notwithstanding anything to the
contrary in this Section 1.7, none of the Exchange Agent, the
Surviving Corporation or any party hereto shall be liable to a holder
of shares of Parent Common Stock for any amount properly paid to a
public official pursuant to any applicable abandoned property, escheat
or similar law.

     1.8    No Further Ownership Rights in Company Capital Stock.  All
shares of Parent Common Stock issued upon the surrender for exchange
of shares of Company Capital Stock in accordance with the terms hereof
(including any cash paid in respect thereof) shall be deemed to have
been issued in full satisfaction of all rights pertaining to such
shares of Company Capital Stock, and there shall be no further
registration of transfers on the records of the Surviving Corporation
of shares of Company Capital Stock which were outstanding immediately
prior to the Effective Time.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any
reason, they shall be canceled and exchanged as provided in this
Article I.

     1.9    Lost, Stolen or Destroyed Certificates.  In the event
any certificates evidencing shares of Company Capital Stock shall have
been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange for such lost, stolen or destroyed certificates, upon the
making of an affidavit of that fact by the holder thereof, such shares
of Parent Common Stock and cash for fractional shares, if any, as may
be required pursuant to Section 1.6; provided, however, that Parent
may, in its discretion and as a condition precedent to the issuance
thereof, require the owner of such lost, stolen or


DMP2HY.R4(5P3)
01/29/94                        -5-
destroyed certificates to deliver a bond in such sum as it may
reasonably direct as indemnity against any claim that may be made
against Parent or the Exchange Agent with respect to the certificates
alleged to have been lost, stolen or destroyed.

     1.10   Tax and Accounting Consequences1.10   Tax and Accounting
Consequences 10  Tax and Accounting Consequences .  It is intended by
the parties hereto that the Merger shall (a) constitute a reorganiza
tion within the meaning of Section 368 of the Code and (b) qualify for
accounting treatment as a pooling of interests.

     1.11   Taking of Necessary Action; Further Action Taking of
Necessary Action; Further Action 11     Taking of Necessary Action;
Further Action .  If, at any time after the Effective Time, any
further action is necessary or desirable to carry out the purposes of
this Agreement and to vest the Surviving Corporation with full right,
title and possession to all assets, property, rights, privileges,
powers and franchises of the Company and Merger Sub, the officers and
directors of the Company and Merger Sub are fully authorized in the
name of their respective corporations or otherwise to take, and will
take, all such lawful and necessary action, so long as such action is
consistent with this Agreement.

                        PURSUANT TO ARTICLE III
                                   

3.1   Organization of the Company.

      1.  Octel has entered into a memorandum of understanding with
Bell Canada International, Inc. for the formation of a limited
liability company in the Netherlands.  A copy of the proposed
Unanimous Shareholders Agreement has been provided to the Company.

      2.  Octel has formed two additional wholly owned subsidiaries:
          -   Octel Communications K.K. (Japan)
          -   Octel Communications Pacific, Ltd (Hong Kong)


3.2   Capital Structure.

1.    45,632 shares of Common Stock remain in an escrow account per
the terms of an acquisition agreement between Octel and Compass
Technology, Inc.


3.5   No Undisclosed Liabilities.

      1.  Penalties.  Parent has numerous International Voice
Information Service contracts which include penalties, limited to 20%
of the contract value, for late or non-delivery of product which at
times Parent has or may become liable for.  However, Parent has to
date negotiated mutually satisfactory agreements with such customers
such that there was no Material Adverse Effect.  Parent believes that
these types of commitments are normal in the course of business in the
international marketplace.

      2.  Brazil.  Parent has negotiated and is in the process of
finalizing a 6-year sales transaction for approximately US$ 3.6
Million in Brazil.  Parent has extended credit in connection with this
transaction.  Due to the volatile nature of  the business and
political climate in Brazil, there is a significant risk that Parent
will be unable to collect all or a part of the amounts owed it
pursuant to this transaction.

      3.  Customs Reclassification.  United States Customs has
reclassified Parent disk drives transferred back into the United
States.  The initial liability is estimated at approximately US$
175,000 should the reclassification be successful.  Parent is
preparing a formal protest in objection to this reclassification.



3.6   Absence of Certain Changes or Events.

      1.  The transaction contemplated by the Agreement, to which this
schedule is attached, will cause changes to the consolidated balance
sheet of the Parent.

      2.  In the event Parent determines it is in its best interest to
settle the Theis litigation, there may be an impact on the results of
operations or financial condition of Parent in the quarter in which
the settlement is entered into, depending on the structure of any
potential settlement arrangement.


3.7   Taxes.

Condition of Equipment

      In August 1992, Parent purchased 22 acres of real property in
Milpitas, California and obtained a policy of title in connec    tion
with the purchase.  In May of 1993 the Company commenced
construction of a 368,000 square foot headquarters facility      which
is due to be completed  in August of 1994. The head    quarters
project may involve construction or mechanics liens    which Parent
believes are in the ordinary course of business.  Parent has no long-
term debt obligation associated with the     purchase of this
property.


3.10  Intellectual Property.

DMP2HY.R4(5P3)
01/29/94                        -3-
              patent related to the use of the phone key pad as a user
interface.
             Other:  Parent is aware of other patents in the
voicemail industry, such as those held by Comverse and
Brooktrout.  In Parent's business judgment, Parent does
not believe it infringes any such patents although,
based on other patent claims brought within the
voicemail industry, it believes that such patents could
entail the risk of a claim.

      2.  Trade Secrets

             VMX has contacted Parent threatening to sue based on
Tigon's reverse engineering of the VMX networking
protocol.

      3.  Trademarks

             Sierra. Octel has received letters from Sierra On-Line
and Sierra Semiconductor regarding alleged infringement

regarding infringement of their trademark.  The parties
are negotiating a final settlement payment.
             Dialect.  Dialog claims that Compass' use of the mark
"dialect" infringes their trademark.

          4.  Confidentiality Agreements, Employees and Consultants.
It            is Parent's standard practice to use best efforts to
assure        that all employees and consultants sign Parent's
standard          agreement regarding Proprietary Rights and
Confidentiality          Agreement or Consultant's Agreement.


3.11  Litigation

          1.  Gilbarco - described under 3.10 disclosures.

          2.  Yates - Julian and Peter Yates, former shareholders of
Compass, have engaged counsel to negotiate an amendment to
their employment agreements including accelerated rights to
exercise outstanding stock options.  The claim is based on
their belief that the Parent made misrepresentations during
the acquisition of Compass Technologies relative to
distribution strategies.

          3.  Other employment claims.  Parent and its subsidiaries
have          various other employment related claims outstanding,
none of       which individually or taken as a whole are expected to
have      a Material Adverse Effect on the Parent or its subsidiaries.

Compensation and long-term disability claims outstanding which   are
not expected, individually or in the aggregate, to have a   Material
Adverse Effect on the business of Parent.

           ANNUAL SENIOR PERSONNEL INCENTIVE (ASPIN) PLAN
                                
                                
                                
                                
                                
                                




1.0  Purpose

     The purpose of the Annual Senior Personnel Incentive ("ASPIN
     Plan") is to provide performance incentives for those
     members of the management of Octel Communications (the
     "Company") and other senior level employees who, in the
     execution of their responsibilities, are in a position to
     significantly influence the performance level for the
     Company.  The ASPIN Plan is designed to encourage the
     achievement of overall Company objectives as well as to
     recognize and reward individual accomplishment.
     
2.0  Term
     
     The term of the ASPIN Plan is 1 year, to coincide with the
     Fiscal Year, commencing July 1, and ending June 30.  The
     ASPIN Plan will be subject to review, modification, and
     renewal by the Board of Directors of the Company (the
     "Board") on an annual basis.
     
3.0  Plan Administration
     
     The ASPIN Plan will be administered by an Executive
     Compensation Committee (the "Committee") composed of
     designated Executive Staff members.  Subject to the review
     and approval of the Chief Executive Officer of the Company
     (the "CEO"), the Committee will have responsibility to
     review and approve: (a) participation levels, (b) target
     bonuses, and (c) individual performance objectives, (d) year-
     end individual performance evaluations, and (e)
     communications to employees regarding the ASPIN Plan.
     
4.0  Eligibility
     
     4.1  Employees of the Company, designated by the Committee,
          will be eligible to participate in the ASPIN Plan.
          Employees hired or promoted into such positions during
          the fiscal year will be eligible to participate, with
          the target bonus for such participants determined
          according to the provisions of Section 5.0 below.
     
     4.2  To be eligible to receive a bonus under the ASPIN Plan,
          the participant must be employed by the Company on the
          last working day of the fiscal year for which the bonus
          is to be paid.  No bonus will be payable if the
          participant is not so employed, provided, however, that
          where termination of employment is due to death or
          disability of the participant, or normal retirement as
          defined by the Company's retirement plan then in
          effect, a pro-rata payment of the bonus may be made, at
          the discretion of the Committee.  The Company also
          reserves the right to withhold payment of any or all of
          the bonus if the employee is on a leave of absence for
          longer than nine months during the fiscal year (to be
          reviewed on a case-by-case basis).
     
5.0  Target Bonuses
     
     5.1  General:  At the start of the ASPIN Plan term a target
          bonus will be set for each participant, based upon the
          responsibility level and appropriate target total
          compensation level for the participant.  All target
          bonuses are subject to the review and approval of the
          Committee.
     
     
     
     
     
     
     5.2  Percentage of Base Salary:  Target bonuses for all
          participants will be expressed as a percentage of gross
          base salary paid during the fiscal year.  For purposes
          of the Plan, "gross base salary" includes base salary
          actually paid to the employee in the current fiscal
          year (before taxes and other deductions).  Excluded
          from earnings will be bonus payments made in the
          current fiscal year for performance in the previous
          fiscal year.
     
     5.3  New Hires/Promotions:  Employees hired or promoted into
          an eligible position during the fiscal year will
          normally have a target bonus set at the minimum of the
          appropriate target bonus range.  Since the target bonus
          percentage applies only to base salary paid during the
          eligibility period, the bonus will be automatically
          prorated.
     
     5.4  Demotions or Reclassifications:  Employees downgraded
          to non-eligible positions during the fiscal year will
          have their bonus participation reviewed on a case-by-
          case basis.  Since the reason for the downgrade could
          be voluntary or involuntary due to individual
          performance or business necessity, the handling of the
          bonus will be subject to review and approval of the
          Committee.
     
6.0  Company Performance Objectives
     
     Company performance objectives for purposes of the ASPIN
     Plan will be recommended by the President/CEO, subject to
     the review and approval of the Board.
     
7.0  Individual Performance Objectives
     
     Individual performance objectives will be set for each
     participant by the participant's immediate supervisor,
     department director, or above, subject to the review and
     approval of the cognizant Executive Staff member.
     Performance objectives will normally be goals that are
     strategic in nature and measurable.
     
8.0  Performance Monitoring
     
     During the ASPIN Plan year, Company and individual
     performance will be monitored.  Adjustments to performance
     objectives may be made where appropriate, subject to the
     review and approval of the Executive Staff member, with
     respect to individual performance objectives.
     
9.0  Performance Criteria Weightings
     
     For all participants, 50% of the bonus will be based upon
     Company performance and 50% will be based upon individual
     performance.
     
10.0 Bonus Determination Process
     
     10.1 Portion of Bonus Based on Company Performance:  At the
          end of the fiscal year, Company performance against
          objectives will be determined according to the audited
          financial statements of the Company.  The portion of
          the target bonus based upon Company performance will be
          adjusted as illustrated in Exhibit A.
     
     
     
     
     
     
     
     
     10.2 Portion of Bonus Based on Individual Performance:  At
          the end of the ASPIN Plan year, an evaluation of
          performance versus plan goals will be made by the
          participant's management.  Such evaluations will be
          subject to the review and approval of the Committee.
          The portion of the target bonus based upon individual
          performance will be adjusted between 0% and 100% based
          upon achievement of performance against measurable
          objectives.
     
     10.3 Total Bonus:  The Company and individual performance
          factors operate independently.  The participant's total
          bonus will be the sum of the portion earned based on
          Company performance and the portion earned based on
          individual performance.
     
     10.4 Minimum Required Performance Levels:  Notwithstanding
          the foregoing, no company-performance bonus will be
          payable to any participant unless the minimum Company
          performance level is achieved.  The Company also
          reserves the right to withhold payment of the
          individual portion of the bonus if the Company is not
          profitable (to be determined at year end).
     
          Further, regardless of Company performance, no bonus
          will be paid to the participant if the participant is
          not meeting general job requirements (a rating of
          "good" or better) as determined by management at the
          end of the fiscal year.  If the participant does not
          receive a bonus because the foregoing minimum
          requirements are not met, the participant may
          nevertheless be eligible to receive an incentive
          payment under the Company's Profit Sharing Plan,
          provided that the eligibility requirements of that plan
          are met.
     
11.0 Bonus Distribution
     
     Bonuses will be distributed to participants as soon as
     practical after the close of the fiscal year for which the
     bonus has been earned.  Such distribution will be subject to
     the eligibility requirements specified in Section 4.0 above.
     
12.0 Miscellaneous
     
     12.1 The ASPIN Plan may be amended or terminated by the
          Company at any time, except that amendment or
          termination will not affect bonus payments made prior
          to such amendment or termination.
     
     12.2 All Bonus payments under the ASPIN Plan are subject to
          the discretion of the Company, and prior to
          distribution, pursuant to the provisions of the ASPIN
          Plan, bonus payments may be reduced or eliminated
          entirely if business considerations of the Company so
          require.
     
     12.3 Participation in the ASPIN Plan does not constitute an
          agreement to employ the participant for any length of
          time, and shall not restrict the Company's right to
          terminate the employment of the participant for any
          reason and at any time.
     
     
     
     
     
     
     
     
     
     12.4 The Board of Directors may, at its discretion,
          partially fund the ASPIN Plan if in its judgment
          factors causing under-achievement vis-a-vis company
          goals were due to circumstances not fully related to
          the performance of the ASPIN participants.  In such
          cases, pro-rata bonuses for all or some of the ASPIN
          participants would be authorized.
