Exhibit 99.5

                 Symmetricom, Inc. and Hewlett-Packard Company
                    Communications Synchronization Business
                            Pro Form Financial Data

On September 30, 1999, subsequent to the first fiscal quarter, Symmetricom, Inc.
("Symmetricom" or the "Company") acquired Hewlett-Packard Company's
Communications Synchronization Business ("Product Line Business") for $19.4
million in cash.  The acquisition has been accounted for under the purchase
method of accounting.  The estimated net purchase price of $19.8 million, which
includes cash paid of $19.0 million, transaction costs of $.4 million, assumed
liabilities of $.4 million was allocated to tangible assets acquired of $1.4
million, capitalized developed technology of $8.0 million, other intangible
assets of $6.9 million and in-process research and development of $3.5 million.
Additionally, an estimated $11.0 million will be paid to Hewlett-Packard Company
over the next 12 to 15 months as additional assets, primarily inventory, are
transferred to the Company.  The purchase price allocation is subject to further
adjustment over the next quarter.

The following condensed consolidated pro forma financial data is based upon the
historical financial statements of Symmetricom for the three months ended
September 30, 1999 (unaudited) and the year ended June 30, 1999 and the
historical financial statements of the Product Line Business for the three
months ended July 31, 1999 (unaudited) and the year ended July 31, 1999.  The
unaudited condensed consolidated pro forma financial data has been prepared to
present, on a pro forma basis, the combined results of the operations of the
Company and the Product Line Business.

The Unaudited Pro Forma Condensed Consolidated Balance Sheet at September 30,
1999 combines the historical balance sheet of the Company and the Statement of
Tangible Assets Sold and Liabilities Assumed of the Product Line Business as if
the acquisition had occurred on September 30, 1999, after giving effect to
certain adjustments described in the accompanying Notes to Unaudited Pro Forma
Condensed Consolidated Balance Sheet.

The Unaudited Pro Forma Condensed Consolidated Statements of Operations for the
year ended June 30, 1999 and for the three months ended September 30, 1999
present the combined results of operations of the Company and the Statement of
Net Sales, Cost of Sales and Direct Operating Expenses of the Product Line
Business as if the acquisition had occurred on September 30, 1999, after giving
effect to certain adjustments described in the accompanying Notes to Unaudited
Pro Forma Condensed Consolidated Statement of Operations. The following
Unaudited Pro Forma Condensed Consolidated Financial Information is presented
for illustrative purposes only. The Gross Margin of the Product Line Business
was significantly impacted by expenses for inventory writeoff, warranty retrofit
programs, the redeployment of resources and ramp up costs of offshore
manufacturing facilities for the year and quarter ended July 31, 1999. We do not
believe that this is indicative of the consolidated financial position or
results of operations for future periods or the results that actually would have
been realized had the Company and the Product Line Business been a consolidated
company during the specified periods.

The Unaudited Pro Forma Condensed Consolidated Financial Information, including
the notes thereto, is qualified in its entirety by reference to, and should be
read in conjunction with the historical consolidated financial statements and
the notes thereto, which were previously reported in the Company's Annual Report
on Form 10-K for the year ended June 30, 1999 and the Quarterly Report on Form
10-Q for the quarter ended September 30, 1999.

This report on Form 8-K contains forward-looking information within the meaning
of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended, and is subject to the safe harbor
created by those Sections. These forward-looking statements include statements
concerning additional payments as assets are transferred to


Symmetricom, purchase price allocation, and future operating results.
Symmetricom's actual results could differ materially from those projected or
suggested in these forward-looking statements. Factors that could cause future
actual results to differ materially from the results projected in or suggested
by such forward-looking statements include: transfer of the assets by
Hewlett-Packard Company; difficulties in integrating the Communications
Synchronization business, products and employees with those of Symmetricom;
reduced rates of growth of telecommunication services and high-bandwidth
applications; timing, cancellation or delay of customer orders; delays in new
product development, introduction and production startup; increased competition;
customer acceptance of new products, including new and existing Communications
Synchronization products; customer delays in qualification of key new products,
including new and existing Communications Synchronization products; and the risk
factors listed from time to time in Symmetricom's reports filed with the
Securities and Exchange Commission.
