                                     PART I


ITEM 1.          BUSINESS.

         The information required by this Item has been omitted pursuant to Rule
12b-25 of the Securities Exchange Act of 1934 and will be filed by amendment.


ITEM 2.          PROPERTIES.

         The Company's executive offices, as well as its principal
manufacturing and diagnostic product engineering and marketing operations, are
located in an approximate 58,200 square-foot facility in Calabasas, California
under a lease which expires in November 2004 with an option to extend for an
additional five years.  The aggregate monthly rental under this lease is
approximately $59,700, subject to certain periodic increases.  
        
         The Company also occupies a 21,600 square-foot facility in Morrisville,
North Carolina (the "Morrisville Facility") under a lease expiring in July
1996, and a 6,800 square-foot facility in Columbus, Ohio under a lease expiring
in March 1999, primarily for engineering, product development, customer support
and regional sales activities.  The Company recently signed two leases for two
additional facilities in Morrisville, North Carolina to provide for anticipated
growth.  The first is a five-year lease (cancelable by the Company under
certain circumstances) for an 8,800 square-foot facility to which the Network
Diagnostic Division employees of the Morrisville Facility will relocate in
April 1995.  The second is a seven-year lease for a 40,000 square-foot facility
to which the Network Switching Division employees of the Morrisville Facility 
will relocate during the fourth quarter of 1995.  The aggregate monthly rental
under the two new leases will be approximately $32,500, subject to certain
periodic increases.  The Company also has eight regional sales offices
occupying an aggregate of approximately 14,500 square feet under leases 
expiring between 1995 and 1997 in Milbrae, California; Boulder, Colorado;
Lombard, Illinois; Nashville, Tennessee; Iselin, New Jersey; Irving, Texas; 
Reston, Virginia; and Whitby, Canada.  The Company's Japanese subsidiary
occupies, at a monthly rental of approximately $37,000, approximately 10,600
square feet in Tokyo under leases expiring between August 1995 and November
1996.  The Company believes that its existing facilities, together with the
additional facilities it has leased in Morrisville, North Carolina, will be
adequate to meet its needs at least through 1995. The Company believes it will
be able to obtain additional space when and as needed on acceptable terms.

         Inapplicable.


ITEM 4.          SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

         The Company has never paid a cash dividend.  It is the present policy
of the Company to retain earnings to finance the future growth and development
of its business and, therefore, the Company does not anticipate paying cash
dividends on its Common Stock in the foreseeable future.  Certain financial
covenants in one of the Company's bank line of credit agreements restrict the
Company's ability to pay dividends.

                      REPORT OF INDEPENDENT ACCOUNTANTS


        Our report on the consolidated financial statements of Tekelec has been
incorporated by reference in this Form 10-K from page 26 of the 1994 Annual
Report to Shareholders.  In connection with our audits of such financial
statements, we have also audited the related financial statement schedule
listed under PART IV, Item 14(a)2 on page 6 of this Form 10-K.

        In our opinion, the financial statement schedule referred to above,
when considered in relation to the basic financial statements taken as a whole,
presents fairly, in all material respects, the information required to be
included therein.

Note

Computation method of benefit rate in case that there should be any fractional
months less than 1 year is as follows;

Benefit rate for the participant with A years and B months of service

=        (Benefit rate corresponding to A years of service)
         +       (Benefit rate corresponding to (A+1) years of service
               -        Benefit rate corresponding to A years of service) x B/12

(Table 1)
If there is any fraction in five or more decimal places, the fraction of 5 or
more in five decimal places shall be counted as 10, and the fraction of less
than 5 shall be disregarded.  Therefore, the benefit rate shall be computed
down to four decimal places.

(Table 2)
If there is any fraction in three or more decimal places, the fraction of 5 or
more in three decimal places shall be counted as 10, and the fraction of less
than 5 shall be disregarded.  Therefore, the benefit rate shall be computed
down to two decimal places.

(Table 3)
If there is any fraction in four or more decimal places, the fraction of 5 or
more in four decimal places shall be counted as 10, and the fraction of less
than 5 shall be disregarded.  Therefore, the benefit rate shall be computed 
down to three decimal places.

                             MEMO OF UNDERSTANDING


This memo of understanding between Stratus Computers and Tekelec signals the
introduction of a unique and valuable partnership to the AIN marketplace.  The
combination of Tekelec's proven SS7 and STP knowledge and expertise and
Stratus' industry proven SINAP product and application solutions will bring to
the targeted market(s) integrated "total" AIN solutions.  In addition, a
"single point of contact" multivendor environment will be offered to the
targeted market(s).

In is envisioned that over time the relationship will evolve from an initial
marketing alliance to one undertaking joint product development and
integration.  For example, a product offering the features and functions of
both an STP and SCP in a single, fault tolerant, scalable system combined with
the benefits of a single Service Creation Environment could result and be
brought to the market.

TARGET MARKET(S)

One of the first objectives of the alliance will be the joint definition and
identification of the target market(s).  This activity will include the
quantification of the number of accounts targeted by year as well as the
specific applications to be offered.  In general, the early targets of the
alliance are believed to be the smaller Local Exchange Carriers (LEC) and
Independent Telephone Companies (ITC) as well as alliances involving multiple
LECs and ITCs.  Included in this effort will be the following activities and
objectives.

1.       Applications required        The specific applications and services required by the targeted market(s) will be
                                      identified.  This will include an estimate of the number of licenses of each application
                                      and/or service to be sold by year by target market.
                                   
2.       Market Segmentation          The classification of the total possible market into market segments based upon such
                                      variables as number of access lines served, construction budget funds, performance
                                      requirements, motivation, state of SS7 deployment, expected in-service dates, etc.

                              profile will be used as a tool to qualify each 
                              specific opportunity presented to the alliance 
                              and to identify the appropriate solution approach.

         o       Joint press releases
         o       Brochures
         o       Trade/Industry/Market forums, tradeshows, seminars, etc.
         o       Industry association contacts (Comptel, OPASTCO, USTA, etc.)

Representatives from Stratus and Tekelec will jointly determine the content of
these items and events.

MARKETING AND SALES ACTIVITIES

It is expected that sales opportunities will be introduced to the alliance by
both Stratus and Tekelec sales personnel.  Over a period of time, each sales
organization will become proficient in the presentation of each other's
products so that each sales group can present the total solution independently,
but for the first several opportunities joint sales call participation is
anticipated.  In addition, joint sales calls when appropriate will always be an
option.

For those accounts target by the alliance, Stratus and Tekelec will act as a
single team to the customer.  Prime point-of-contact will be determined on a
case-by-case basis as determined by Stratus and Tekelec marketing.

Coordination and logistics of sales presentations, the generation of quotations
and pricing and discount strategies will be the mutual responsibility of
Stratus and Tekelec marketing.

SUPPORT

The alliance must continue to be flexible in its approach to the market place
in the area of product support.  To a large degree, the needs and requirements
of the customer will dictate the appropriate approach to be used in providing
product support.  It is the intent of the alliance to allow the continued
provision of each parties' current methods and options of providing support to
customers.  This philosophy includes but is not limited to extended warranty
packages, system acceptance assistance and network interoperability activities
support.  Stratus and Tekelec will continue discussions exploring strategies
and approaches to providing post-sales support.

PRODUCT STRATEGY PLANNING

As mentioned previously, Stratus and Tekelec will commit to explore the market
opportunities and requirements which may be addressable by the development of
an integrated AIN platform(s) utilizing Tekelec and Stratus technologies.
Network elements may include Service Nodes/Intelligent Peripherals, Service
Control Points, etc.

NONEXCLUSIVITY

Neither party grants or accepts any exclusivity arrangements to or with the
other party.

TERM OF AGREEMENT

This agreement shall be for a term of 1 year from date of signing.  The

TEKELEC   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS


The following discussion should be read in conjunction with, and is qualified
in its entirety by, the Consolidated Financial Statements and the Notes thereto
included in this Annual Report. Historical results and percentage relationships
among any amounts in the financial statements are not necessarily indicative of
trends in operating results for any future periods.

CORPORATE ORGANIZATION

The Company is organized into two divisions: Network Diagnostic and Network
Switching.

The Network Diagnostic Division supplies diagnostic products and systems for
the communications marketplace. Its products are the foundation of the
Company's business and the source of the technology and expertise that has 
facilitated the Company's entry into other markets.

The Network Switching Division capitalized on the Company's expertise in
diagnostic systems for SS7 to develop the EAGLE, a high-capacity,
fault-tolerant data communications switching platform first
introduced in 1992.

As more fully described below, the Company experienced significant losses in
1992 and 1993 but returned to profitability in 1994 as a result of actions
taken in connection with its December 1993 restructuring and increased market
acceptance of its products, particularly the EAGLE STP and the Chameleon Open.
The cost savings realized in connection with such restructuring were consistent
with those anticipated.  See Note E to Consolidated Financial Statements.

1994 COMPARED WITH 1993

REVENUES

The Company's revenues increased by $14.3 million or 31% during 1994 due to
higher sales of both switching and diagnostic products.

Revenues from switching products doubled in 1994 to $16.8 million due to
growing market acceptance of the Company's EAGLE STP product, particularly in
the cellular market. In 1994, 23 pairs of EAGLE STPs were sold (including one
pair sold under the Company's September 1994 distribution agreement with AT&T)
compared with 13 in 1993. The Company expects that 1995 sales of its network
switching products will continue to grow both in dollars and as a percentage of
total revenues although at a reduced percentage rate of growth compared with
1994.

Revenues from diagnostic products increased by 15%, or $5.8 million, to $44.3
million. This increase was primarily driven by an $8.8 million increase in      
worldwide sales of the Chameleon Open (which was first shipped in the second
quarter of 1993) and the September 1994 introduction of the Company's ATM
Application Module for this product. Sales of the Chameleon Open represented
26% of 1994 total diagnostic product sales compared with 7% in 1993. These
increases were partially offset by lower worldwide sales of certain older 
diagnostic products as the Company continued its product evolution to the
Chameleon Open platform supporting multiple protocol diagnostics. The Company 
expects that 1995 sales of its Chameleon Open will continue to grow both in 
dollars and as a percentage of diagnostic product revenues although at a
reduced percentage rate of growth compared with 1994.

Revenues in North America increased by $10.8 million or 43% as a result of      
higher switching and diagnostic product sales. Despite slightly lower sales of
diagnostic products, revenues in Japan increased by $520,000 or 4% due to the
impact of favorable exchange rates in 1994. Other international revenues grew
$3.0 million or 31% primarily due to higher switching product sales.

The impact of exchange rate fluctuations on currency translations increased
revenues by approximately $1.0 million or 2% and increased net income by
$86,000 or 2%.

GROSS PROFIT

Gross profit as a percentage of revenues improved from 64% in 1993 to 67% in
1994 principally due to lower per unit manufacturing overhead costs and higher
margins on EAGLE sales due to shipments of larger systems and reduced sales
discounts. The gross profit percentage on switching products is generally lower
than on diagnostic products. Changes in the following factors, among others, may
affect gross profit: product and distribution channel mix, competition,
customer discounts, supply and demand conditions in the electronic components
industry, internal manufacturing capabilities and efficiencies, foreign
currency fluctuations and general economic conditions.

RESEARCH AND DEVELOPMENT

Research and development expenses in 1994 decreased by $5.6 million or 32% and
from 38% to 20% as a percentage of revenues. These decreases were attributable
primarily to reduced headcount in research and development and termination of
certain projects following the December 1993 restructuring in which certain
product lines were discontinued. Expenses related to EAGLE also declined due to
completion of its initial development.

The Company believes that its future success depends in large part upon its
ability to continue to enhance existing products and develop new products that
maintain its technological competitiveness. The Company intends to continue to
make substantial investments in product and technology development, and
believes that total research and development expenses will not change
significantly as a percentage of revenues in 1995.

          RESULTS OF OPERATIONS


SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expenses in 1994 decreased by $1.3 million
or 5% primarily as a result of the December 1993 restructuring.  The decline
due to the restructuring was partially offset by employee bonuses and
increased sales commissions based upon the achievement in 1994 of certain
business performance targets.

INCOME TAXES

In 1994, the Company had an effective tax rate of 22%, compared to 8% in 1993.
The provisions for both years were principally foreign taxes on the income of
the Company's Japanese subsidiary.  In 1994, the Company was able to utilize a
portion of its prior years' U.S. loss carryforwards, and consequently provided
for taxes on its U.S. taxable income at the federal alternative minimum tax
rate and applicable state tax rates.

The 1993 provision was impacted by the Company's inability to recognize a
benefit for its U.S. loss and credits carryforwards, which remain available to
reduce future U.S. taxes.

The Company anticipates that it has sufficient loss and credits carryforwards
available in 1995 to offset its expected U.S. taxes, and therefore its federal
and state effective tax rates should be similar in 1995 to those in 1994.
However, the Company's overall tax rate is significantly influenced by the
level of income derived from its Japanese subsidiary.

BACKLOG

Orders for the Company's diagnostic division products are usually placed by
customers on an as-needed basis, and the Company has typically been able to
ship these products in 15 to 30 days after the receipt of the purchase order.
Backlog for the switching division typically consists of contracts or purchase
orders for both product delivery scheduled within the next 12 months and EAGLE
extended service warranty to be provided over the next three years. Because of
variations in the magnitude and duration of orders received by the Company, and
customer delivery requirements, which may be subject to cancellation or
rescheduling, the Company's backlog at any particular date may not be a
meaningful indicator of future financial results. At December 31, 1994, the
Company's backlog amounted to approximately $18.1 million, of which $8.6
million related to EAGLE service warranty, compared to $9.9 million at
December 31, 1993, of which $3.1 million related to EAGLE service warranty.

1993 COMPARED WITH 1992

REVENUES

The Company's revenues declined by $11.2 million or 19% during 1993 primarily
due to lower sales of diagnostic products, partially offset by increased sales
of switching products.

The decrease in revenues was primarily due to delayed product introductions and
difficult economic conditions worldwide. As part of its restructuring, the
Company further rationalized its business lines to enhance its ability to be
successful within its resource constraints for 1994 and thereafter. See
"Restructurings."

Revenues from diagnostic products decreased by $15.7 million or 29%.
Of this amount, sales of the signalling/wireless diagnostic products decreased
by $9.3 million or 43% primarily due to lower sales in the U.S. following an
unusually high level of sales during the first nine months of 1992, which was
primarily related to the significant SS7 deployment by the Regional Bell
Operating Companies (RBOCs). In addition, sales of diagnostic products for LAN
and WAN applications decreased by $5.8 million or 20% due primarily to lower
worldwide sales of LAN and field service protocol analyzers. This decrease
was partially offset by sales of the Chameleon Open which first shipped in the
second quarter of 1993. Sales of LAN protocol analyzers declined due to a
slowed market for FDDI research and development, the emergence of competing
technologies such as ATM and increased competition.

Revenues from switching products increased by $4.5 million or 115%
primarily due to higher sales of EAGLE products in the U.S., higher sales of
other switching products in Canada, and the first international EAGLE STP sale
in New Zealand.

Revenues in North America decreased by $9.1 million or 27% primarily as a result
of lower sales of diagnostic products partially offset by higher switching
product sales. Sales in Japan decreased by $782,000 or 6% due to lower field
service diagnostic product sales. Other international sales decreased by $1.3
million or 12% primarily due to lower sales of LAN/WAN and field service
diagnostic products, partially offset by the first international EAGLE STP sale.

The impact of exchange rates fluctuations on currency translations increased
revenues by $1.4 million or 3% and decreased net loss by $100,000 or 1%.

          RESULTS OF OPERATIONS


GROSS PROFIT

Gross profit as a percentage of revenues decreased from 68% in 1992 to 64% in
1993 principally due to changes in the product mix of the Company's sales and a
higher percentage of fixed overhead costs due to lower revenues. The changes in
the product mix reflected a shift in the Company's sales to a lower proportion
of sales of higher margin signalling/wireless diagnostic products and a higher
proportion of EAGLE products which carried lower margins than the Company's
traditional diagnostic business due to marketing strategies to gain market
position.

RESEARCH AND DEVELOPMENT

Research and development expenses increased by $1.4 million or 9% in 1993. This
increase was due primarily to the hiring of additional engineering personnel
and increased third-party contractor costs incurred in connection with the
ongoing development of EAGLE, which was in the early stages of its product life
cycle.

Research and development expenses increased as a percentage of revenues
primarily due to lower than anticipated overall revenues and increased expenses
as described above. Research and development expenses for the EAGLE product
accounted for approximately 36% of the total research and development expenses
for 1993.

The Company also capitalized software development costs totaling $165,000
in 1993 related principally to SMDS, the Company's new broadband WAN
application, as compared to $2.6 million in 1992.

SELLING, GENERAL AND ADMINISTRATIVE

Selling, general and administrative expenses decreased by 13% in 1993. Selling
expenses decreased by $2.3 million and general and administrative expenses
decreased by $1.3 million, primarily as a result of the expense reduction
measures implemented as part of the December 1992 restructuring and lower legal
expenses, partially offset by a currency translation effect of approximately
$450,000 on the Company's foreign operations.

RESTRUCTURINGS

During 1993 and 1992 the Company recorded restructuring charges of $6.0 million
and $2.8 million, respectively. See Note E to Consolidated Financial
Statements.

INCOME TAXES

Although the Company's pre-tax results showed a loss for the years ended
December 31, 1993 and 1992, the effective tax rates were 8% and 24%,
respectively. The provisions principally consisted of foreign taxes on the
income of the Company's Japanese subsidiary and reflected the Company's
inability to recognize any benefit for its U.S. loss and credits carryforwards,
which remain available to reduce future U.S. taxes.

LIQUIDITY AND CAPITAL RESOURCES

The Company has financed its net working capital and capital expenditure
requirements principally from operations, available cash, and utilization from
time to time of its U.S. credit facilities. At December 31, 1994, the Company
had $6.7 million of cash and cash equivalents, representing an increase of $3.0
million from December 31, 1993 primarily attributable to net cash provided by
operating activities.

Accounts receivable, including amounts due from related parties, increased by
63% during 1994 due primarily to a 61% increase in sales for the fourth quarter
of 1994 over 1993 fourth quarter sales. A significant portion of the Company's
quarterly sales are concentrated in the last month of each quarter. Inventories
decreased by 7% during 1994 primarily due to continued efforts to maximize
inventory efficiency.

Capital expenditures were reduced to $1.5 million during 1994 in connection
with steps taken to improve the Company's liquidity following the December 1993
restructuring. Although there are currently no significant commitments for
capital expenditures, the Company expects that its capital expenditures will
increase significantly in 1995, primarily in connection with the planned
acquisition of equipment for research and development and sales demonstration.

The net cash provided by financing activities in 1994 was $338,000 which
represented $1.6 million in proceeds from the issuance of Common Stock
resulting from the exercise of options and warrants, and $860,000 in net
proceeds from the issuance of long-term debt, offset primarily by repayments of
short-term borrowings.

The Company has a $7.5 million line of credit and a $2.0 million line of credit
with U.S. banks and lines of credit aggregating $3.5 million available to the
Company's Japanese subsidiary from various Japan-based banks.

TEKELEC   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS


The Company's $7.5 million line of credit with a U.S. bank is collateralized by
substantially all of the Company's assets, bears interest at the U.S. prime
rate (8.5% at December 31, 1994) plus 2.5% per annum and expires September 30,
1995, if not renewed. Maximum borrowings available under the line of credit are
based on eligible accounts receivable and amounted to $6.6 million at December
31, 1994, of which $126,000 was then outstanding. This line of credit includes  
a $1.0 million long- term credit facility payable in monthly installments
through May 1998 or upon the expiration of the underlying $7.5 million line
of credit, if not renewed. At  December 31, 1994, $860,000 was outstanding
under this long-term facility, of which $620,000 was included under long-term
debt.

In February 1994, the Company established a $2.0 million line of credit with a
U.S. bank collateralized by restricted cash deposits in Japan, with interest at 
the U.S. prime rate plus 0.375% per annum. This line of credit expires May 31,
1995, if not renewed. Borrowings at any time may not exceed the cash amount on
deposit. At December 31, 1994, $1.0 million was outstanding under this line of
credit.

The Company's Japanese subsidiary has collateralized yen-denominated lines of
credit with Japan-based banks, primarily available for use in Japan,    
amounting to the equivalent of $3.5 million with interest at the Japanese prime
rate (3% at December 31, 1994) plus 0.125% per annum which expire between May
29, 1995 and March 31, 1996, if not renewed. There have been no borrowings
under these lines of credit.
        
Upon the expiration of the above-described credit facilities, the Company
believes that, if necessary, it would be able to arrange for credit facilities
on terms generally no less favorable than those described above.

The Company believes that funds generated from operations, existing working
capital and current bank lines of credit should be sufficient to satisfy
anticipated operating requirements for 1995. Nonetheless, the Company may seek
additional sources of capital, including a possible public offering of its
Common Stock, as necessary or appropriate to finance its operations and growth;
however, there can be no assurance that such funds will be available on
favorable terms, if at all.

FOREIGN EXCHANGE

International operations are subject to certain opportunities and risks,
including currency fluctuations. In 1994, 1993, and 1992, weighted average
exchange rates for certain key currencies strengthened (weakened) against the
U.S. dollar as follows:

======================================================================================================
</TABLE>

(1) 1992 not applicable as the Company's Canadian operations did not begin
operation until 1993.

The change in cumulative translation adjustment in 1994 was due primarily to
the strengthening of the Japanese yen against the U.S. dollar.  Exchange gains
(losses) are recorded in interest and other income (expense), net and amounted 
to $(235,000), $253,000, and $(132,000) in 1994, 1993, and 1992, respectively.
Exchange gains and losses include the remeasurement of certain currencies into
functional currencies and the settlement of intercompany balances.

TEKELEC   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION AND PRESENTATION

The consolidated financial statements include the accounts of the Company and
its subsidiaries. All significant intercompany accounts and transactions are
eliminated. Certain items shown in the December 31, 1993 and 1992 financial
statements have been reclassified to conform with the current period
presentation.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid debt instruments purchased with a
maturity of three months or less to be cash equivalents.

INVENTORIES

Inventories are stated at the lower of cost (first in, first out) or market.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost, less accumulated depreciation and
amortization. Depreciation and amortization are provided using the
straight-line method. The estimated useful lives are:

<TABLE>
<S>                                              <C>
Manufacturing and development equipment          3-5 years
Furniture and office equipment                   5 years
Demonstration equipment                          3 years
Leasehold improvements                           The shorter of useful life or lease term
</TABLE>

TECHNOLOGY

Product development costs, including costs of purchased and licensed technology
incurred to enhance significantly a product that results in the creation and
sales of a new generation of products, are capitalized; costs incurred in
conceptualization and design of new products are expensed as incurred.

Amortization is based on the greater of related net shipments made during the
period to total anticipated net shipments, or the three-year straight-line
method. There were no capitalized internally developed software costs in 1994
and 1993. Capitalized internally developed software costs for 1992 were
$472,000.

PRODUCT WARRANTY COSTS

The Company generally warrants its products for one year after sale and
provides for estimated future warranty costs at the time revenue is recognized.
At December 31, 1994 and 1993, accrued product warranty costs amounted to
$827,000 and $280,000, respectively, and are included in accrued expenses.

REVENUE RECOGNITION

Revenues from sales of diagnostic products are generally recognized when
products are shipped. Revenues from sales of switching products are recognized
upon shipment to the customer's final site for installation and satisfaction
of any related significant Company obligations.  Extended warranty service
revenues are recognized ratably over the warranty period. Engineering service
revenues are recognized on delivery or as the services are performed.

INCOME TAXES

Income tax expense is the tax payable for the period and the change during the
period in deferred tax assets and liabilities. Deferred income taxes are
determined based on the difference between the financial reporting and tax
bases of assets and liabilities using enacted rates in effect during the year
in which the differences are expected to reverse. Valuation allowances are
established when necessary to reduce deferred tax assets to the amount expected
to be realized.

TRANSLATION OF FOREIGN CURRENCIES

Translation of foreign currencies is accounted for using the local currency as
the functional currency of the Company's foreign subsidiaries.  All assets and
liabilities are translated at current exchange rates while revenues and
expenses are translated at average rates in effect for the period. The
resulting gains and losses are included in a separate component of
shareholders' equity. Gains (losses) on foreign currency transactions are
reflected in net income (loss) and amounted to $(235,000), $253,000, and 
$(132,000) for 1994, 1993, and 1992, respectively.

EARNINGS (LOSS) PER SHARE

Earnings (Loss) per share are computed using the weighted average number of 
shares outstanding and dilutive common stock equivalents (options and warrants).

NOTE B -- RESTRICTED CASH

At December 31, 1994, the Company's Japanese subsidiary had $1.0 million of
restricted cash included in current assets, which represents cash on deposit at
a bank in Japan as collateral for outstanding short-term borrowings in the U.S.
under a $2.0 million line of credit. See Note J.

TEKELEC   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE C -- CONCENTRATION OF CREDIT RISK

The Company sells communications diagnostic and network systems worldwide
primarily to telephone operating companies, equipment manufacturers, and
corporations that use its systems to design, install, maintain, test and
operate communications equipment and networks. Credit is extended based on an
evaluation of each customer's financial condition, and generally collateral is
not required. Credit losses, if any, have been provided for in the financial
statements and have been consistently within management's expectations.

The Company places its temporary cash investments in high credit quality
financial instruments and limits the amount of credit exposure to any one
issuer. Generally, the investments made mature within 90 days.

NOTE D -- RELATED PARTY TRANSACTIONS

As of December 31, 1994, the Company's principal shareholder, a director and
his family, and a foreign-affiliated company controlled by the director owned
an aggregate of approximately 47% of the Company's outstanding stock.

The following is a summary of transactions and balances with these affiliates:

a director pursuant to which such director received $52,000 and a warrant to
purchase 20,000 shares of the Company's Common Stock. See Note P.

NOTE E -- RESTRUCTURINGS

During the fourth quarter of 1992, the Company announced a restructuring plan 
designed to reduce operating expenses and scale back product lines that had
not met profitability expectations and that were not anticipated to contribute
to the Company's long-term strategy. In connection with this restructuring, the
Company recorded a $2.8 million charge consisting of severance costs for 33
terminated employees in management, research and development, support and
administrative functions and the write-down of  technology and other assets
associated with the scaled back product lines.
        
During the second quarter of 1993, management reorganized the Company into a
divisional structure and in connection with such reorganization, the Company
recorded a $400,000 restructuring charge consisting of severance costs
associated with the related termination of employees and closure of the
Company's Alabama facility.

After incurring continued losses, the Company implemented in the fourth quarter
of 1993, an organizational and strategic restructuring aimed at returning the
Company to profitability by significantly reducing overhead expenses and
improving cash flow and further rationalizing the Company's business lines. In
connection with this restructuring, the Company discontinued its network
monitoring and field service product lines. A restructuring charge of $5.6
million was recorded representing severance pay for 65 terminated employees in
management, research and development, support and administrative functions, the
write-down of technology and other assets associated with the discontinued
product lines, the write-off of a management information system project which
the Company terminated and the accrual of other exit costs associated with the
restructuring, including costs related to the sale of the Company's Australian
subsidiary.

Restructuring charges consisted of the following:

At December 31, 1994, the Company had available federal net operating loss
carryforwards of $14.8 million, foreign tax credit carryforwards of $918,000
and research and development credit carryforwards of $1.1 million which will
generally expire beginning in the years 2007, 1997 and 2007, respectively.

The Company has not provided for federal income taxes on $8.0 million of
undistributed earnings of its foreign subsidiaries which have been reinvested
in their operations. If these earnings were distributed, net operating loss
carryforwards and foreign tax credits available under current law would
eliminate the resulting federal income tax liability.

NOTE I -- TECHNOLOGY

Technology consists of capitalized product development costs, net of
accumulated amortization of $1.2 million and $1.1 million at December 31, 1994
and 1993 respectively.

NOTE J -- BORROWINGS

The Company has a $7.5 million line of credit and a $2.0 million line of credit
with U.S. banks and lines of credit aggregating $3.5 million available to the
Company's Japanese subsidiary from various Japan-based banks.

The Company's $7.5 million line of credit with a U.S. bank is collateralized by
substantially all of the Company's assets, bears interest at the U.S. prime
rate (8.5% at December 31, 1994) plus 2.5% per annum and expires September 30,
1995, if not renewed. Maximum borrowings available under the line of credit are
based on eligible accounts receivable and amounted to $6.6 million at December
31, 1994, of which $126,000 was then outstanding. This line of credit includes
a $1.0 million long-term credit facility payable in 47 monthly installments     
of $20,000 each which began in June 1994 and a final installment of $60,000 due
in May 1998 or upon the expiration of the underlying $7.5 million line of
credit, if not renewed. At December 31, 1994, $860,000 was outstanding under
this long-term facility, of which $620,000 was included under long-term debt.

In February 1994, the Company established a $2.0 million line of credit with a
U.S. bank, collateralized by restricted cash deposits in Japan, with interest
at the U.S. prime rate plus 0.375% per annum. This line of credit expires May
31, 1995, if not renewed. Borrowings at any time may not exceed the cash amount
on deposit. At December 31, 1994, $1.0 million was outstanding under this line
of credit.

The Company's Japanese subsidiary has collateralized yen-denominated lines of
credit with Japanese-based banks, primarily available for use in Japan,
amounting to the equivalent of $3.5 million with interest at the Japanese
prime rate (3% at December 31, 1994) plus 0.125% per annum which expire
between May 29, 1995 and March 31, 1996, if not renewed. There have been no
borrowings under these lines of credit.

The Company's weighted average short term borrowing rates were 8.8% and 7.2% in
1994 and 1993, respectively.

NOTE K -- COMMITMENTS AND CONTINGENCIES

The Company leases its office and manufacturing facilities together with
certain office equipment under operating lease agreements. Lease terms
generally range from one to ten years; certain building leases contain options
for renewal for additional periods and are subject to increases up to 10% every
24 months.

Total rent expense was $2.0 million, $2.1 million, and $1.8 million, for 1994,
1993, and 1992, respectively.

Minimum annual non-cancelable lease commitments at December 31, 1994, are:

TEKELEC  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Tekelec typically operates with a limited backlog, and most of its revenues in
each quarter result from orders booked in that quarter. Further, Tekelec
typically generates up to one-half of its revenues for each quarter in the last
month of the quarter. Tekelec establishes its expenditure levels based on its
expectations as to future revenues, and if revenue levels were to fall below
expectations this would cause expenses to be disproportionately high.
Therefore, a drop in near term demand would significantly affect revenues,
causing disproportionate reduction in profits or even losses in any quarter.
Tekelec's operating results may fluctuate for this reason or as a result of a
number of other factors, including general economic and political conditions
(such as recessions in the U.S. and Japan), capital spending patterns of
Tekelec's customers, increased competition, variations in the mix of sales,
fluctuation in proportion of foreign sales and announcements of new products by
Tekelec or its competitors. In 1994, Tekelec's quarterly revenues increased by
up to 61% as compared to prior year's quarters. The Company believes these
increases resulted from increased market acceptance of its products. The
Company's results for 1993 include pre-tax restructuring charges amounting to
$400,000 in the second quarter and $5.6 million in the fourth quarter and the
effect of the Company's inability throughout the year to currently recognize
benefits amounting to $8.0 million for its tax loss and credits carryforwards.
The Company's results for 1994 include the effect of the Company's ability to
recognize benefits amounting to $1.6 million for its tax loss carryforwards.

NOTE P -- COMMON STOCK

At December 31, 1994 and 1993, the Company had warrants outstanding to purchase
an aggregate of 80,000 and 20,000 shares of its Common Stock, respectively, as
more fully discussed below.

In July 1994, the Company issued warrants to purchase 30,000 shares of its
Common Stock at $2.875 per share, exercisable in full at any time prior to July
21, 1999, all of which were outstanding at December 31, 1994.

In April 1994, the Company issued warrants to purchase 10,000 shares of its
Common Stock at $3.375 per share to one director, all of which were outstanding
at December 31, 1994. These warrants vest and become exercisable in 20 equal
quarterly installments beginning on April 19, 1994.

In January 1994, pursuant to a consulting agreement between the Company and a
director, the Company issued warrants to purchase 20,000 shares of its Common
Stock at $3.4375 per share to such director, all of which were outstanding at
December 31, 1994. These warrants vested during 1994, and are exercisable in
full at any time prior to January 20, 1999.

In 1992, the Company issued warrants to purchase a total of 20,000 shares of
its Common Stock to two directors at $7.5625 per share. These warrants were
re-priced to $3.595 per share in 1993, are exercisable in full at any time
prior to January 17, 1997, and were outstanding at December 31, 1994 and 1993.

On March 17, 1995, the Company effected a two-for-one stock split. All
references to numbers of shares and related prices, per share amounts, and
stock option plan data have been restated to reflect the stock split.

TEKELEC   REPORT OF INDEPENDENT ACCOUNTANTS


TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF TEKELEC

We have audited the accompanying consolidated balance sheets of Tekelec as of
December 31, 1994 and 1993, and the related consolidated statements of
operations, shareholders' equity, and cash flow for each of the three years in
the period ended December 31, 1994. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation.  We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Tekelec as of
December 31, 1994 and 1993, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1994 in
conformity with generally accepted accounting principles.
