Item 2.  Acquisition or Disposition of Assets.

Acquisition of Linfinity Microelectronics, Inc.
- -----------------------------------------------

(a)  On April 15, 1999, Microsemi Corporation, a Delaware corporation (the
"Registrant"), issued a news release which announced that the Registrant's
wholly-owned subsidiary, Micro Linfinity Acquisition Corporation ("Merger Sub"),
merged with and into Linfinity Microelectronics, Inc., a Delaware corporation
("Linfinity") effective April 14, 1999.  The Registrant's news release
concerning the merger is attached as Exhibit 99.1 hereto and incorporated herein
by this reference.

  The merger resulted in the Registrant owning all of the capital stock of
Linfinity in exchange for $24,125,001 in cash. The shareholders of Linfinity
approved the merger at a special meeting of the Linfinity shareholders held on
March 22, 1999. Linfinity was the surviving corporation in the merger. Microsemi
financed the acquisition with cash on hand and borrowings under its new credit
facility from Canadian Imperial Bank of Commerce, Imperial Bank and City
National Bank. Of the purchase price, $1.125 million was deposited into an
escrow to provide funds for potential claims for indemnification under certain
provisions of the Merger Agreement, as defined below. The escrow has a maximum
term of two years. With certain exceptions, the Registrant's claims under the
Merger Agreement for indemnification may be made only against the amount
deposited into the escrow.

  The merger was consummated pursuant to an Agreement and Plan of Reorganization
dated as of February 10, 1999 ("Merger Agreement") among the Registrant, Merger
Sub, Linfinity, and SymmetriCom, Inc., a California corporation which owned a
majority of the capital stock of Linfinity ("SymmetriCom"). The Merger Agreement
is attached as Exhibit 2.2 hereto and incorporated herein by this reference. The
purchase price was determined by negotiation between the parties.

(b)  The Registrant intends to continue to operate Linfinity as a stand-alone
subsidiary, operating its property, plant and equipment in Garden Grove,
California.  The Registrant's news release concerning the merger is attached as
Exhibit 99.1 hereto and incorporated herein by this reference.

SECTION 1.07     Conversion of Shares.  Subject to Section 2.01 below, at the
Effective Time, by virtue of the Merger and in accordance with the provisions of
the Company's Certificate of Incorporation and based on an aggregate purchase
price payable for all the capital stock of Linfinity in the Merger of
$24,125,001 (the "Purchase Price"), without any action on the part of
SymmetriCom, Linfinity, Purchaser, Purchaser Sub or the holders of the following
securities, each share of Linfinity Preferred Stock and each share of Linfinity
Common Stock issued and outstanding immediately prior to the Effective Time
(together the "Shares") (other than Dissenting Shares) shall be converted into
the right to receive $2.964569 (the "Preferred Price Per Share") and $1.464569
(the "Common Price Per Share") (assuming and to be adjusted on the basis that
there are 6,000,000 shares of Preferred Stock outstanding, 4,197,824 shares of
Common Stock outstanding, 121,449 options outstanding at an exercise price of
$0.50 and 109,000 options outstanding at an exercise price of $0.80),
respectively, without interest thereon, upon surrender of the certificate
formerly representing such Share.  The Preferred Price Per Share and the Common
Price Per Share will be adjusted as provided in the Company's Certificate of
Incorporation in the event of a change in the number of outstanding shares of
Preferred Stock or Common Stock from that set forth in the preceding sentence.
The aggregate Preferred Price and the aggregate Common Price will be rounded
down to the nearest cent after aggregating all Shares held by such stockholder.

SECTION 1.08     Conversion of Purchaser Sub Common Stock.  At the Effective
Time, each share of Common Stock, par value $.001 per share, of Purchaser Sub
issued and outstanding immediately prior to the Effective Time shall, by virtue
of the Merger and without any action on the part of the holder thereof, be
converted into and become one validly issued, fully paid and non-assessable
share of Common Stock, par value $.01 per share, of the Surviving Corporation.

SECTION 1.09     Company Option Plan.
(a)     Linfinity shall (i) terminate its 1993 Stock Plan (the "Option Plan") as
of the Effective Time and (ii) grant no additional Options, restricted stock,
stock units, performance units, performance shares, fixed awards or similar
rights or awards under the Option Plan or otherwise on or after the date hereof.
As used hereafter in this Section 1.09, "Options" shall include each stock
option or other right to acquire Shares (whether or not then exercisable, and
regardless of the exercise price thereof) granted by Linfinity, whether pursuant
to the Option Plan or otherwise, to an employee, agent, consultant, advisor or
director of Linfinity.
(b)     Linfinity shall cancel each Option as of the Effective Time pursuant to
the terms of the Option Plan and without limitation to the foregoing, after
having given at least fifteen (15) days notice to each holder of Options of the
material terms of this Agreement.  In consideration for each cancellation of an
Option, the holder of such Option shall be entitled to be paid out of the
Purchase Price an amount equal to the product of (i) the excess of the Common
Price Per Share over the per Share exercise price of such Option (the "Option
Price Per Share"), and (ii) the number of Shares subject to such Option and
Linfinity will deliver to the holder of such Options an "Option Cancellation
Certificate."  For the avoidance of doubt, Options with an exercise price of
$0.50 will

                                       3
<PAGE>
 
be entitled to $0.964569 and Options with an exercise price of $0.80 will be
entitled to $0.664569 The aggregate price to be paid to the holder of any Option
will be rounded down to the nearest cent after aggregating all Options for which
payment will be made as held by such Optionholder.  No consideration will be
paid to the holder of an Option the per share exercise price of which exceeds
the Common Price Per Share.  Except for Purchaser's payment of the Purchase
Price as expressly provided in Section 1.07, SymmetriCom shall indemnify and
hold harmless Purchaser and the Company from and against any cost or liability
arising in connection with Options.

SECTION 1.10     Cash and Inter-Company Loan.  Prior to the Effective Time,
Linfinity shall pay payables and collect receivables in the ordinary course,
consistent with past practice, and neither defer payables nor accelerate
collections.  Immediately prior to the Effective Time, Linfinity shall use all
available cash to pay all of the outstanding principal and accrued interest on
that certain Inter-Company Revolving Loan Agreement (the "Inter-Company Loan")
by and among Linfinity and SymmetriCom as Lender, dated August 15, 1998, and to
the extent that there is insufficient cash to pay such outstanding amount, such
Inter-Company Loan shall be canceled.  To the extent that there is surplus cash
after payment of the Inter-Company Loan prior to Closing, SymmetriCom shall be
entitled to apply such excess cash for purposes of covering the assumption by it
of the Bonus Plan as set forth in Section 1.11 hereof and for any other cash
payments to be made to employees as a result of the consummation of this
Agreement.

SECTION 1.11     Assumption of Strategic Partner Bonus Plan.  Immediately prior
to the Effective Time, SymmetriCom shall have legally assumed by way of
assignment or otherwise the entire rights and obligations of Linfinity under
that certain Strategic Partner Bonus Plan (the "Bonus Plan") entered into among
Linfinity and the beneficiaries thereunder in August 1998 relating to the
payment of special bonuses in connection with the sale of Linfinity, a copy of
which has been provided to Purchaser.  SymmetriCom will indemnify and hold the
Purchaser and the Company harmless in respect of any claim or liability arising
in connection with the Bonus Plan.

SECTION 1.12     The Company's Stockholders' Meeting.  The Company shall take
all action in accordance with the federal and state securities laws, the GCL,
and the Company's Certificate of Incorporation and By-laws necessary to convene
a special meeting of the Company's Stockholders' (the "Company's Stockholders'
Meeting") to be held on the date determined by the Company and acceptable to
Purchaser, to consider and vote upon approval of the Merger, this Agreement and
the transactions contemplated hereby, including the Company's Board of
Director's Recommendation that the Company Stockholders' approve the Merger.

SECTION 1.13     Proxy Statement for the Stockholders' Meeting.  Consistent with
the timing for the Company's Stockholders' Meeting as determined by the Company,
the Company shall use all reasonable efforts to mail at the earliest practicable
date to the Company Stockholders, a proxy statement regarding the proposed
Merger, which shall include all information required under applicable law to be
furnished to the Company's Stockholders in connection with the Merger and the

                                       4

transactions contemplated thereby and hereby and shall include the Company's
Board of Director's Recommendation that the Company Stockholders' approve the
Merger.

ARTICLE II

DISSENTING SHARES; PAYMENT FOR SHARES

SECTION 2.01     Dissenting Shares
(a)     Notwithstanding anything in this Agreement to the contrary, Shares
outstanding immediately prior to the Effective Time and held by a holder who has
not voted in favor of the Merger or consented thereto in writing and who has
demanded appraisal for such Shares in accordance with Section 262 of the GCL, if
such Section 262 provides for appraisal rights for such Shares in the Merger
("Dissenting Shares"), shall not be converted into the right to receive the
Preferred Price Per Share or Common Price Per Share, as the case may be,  as
provided in Section 1.07, unless and until such holder fails to perfect or
withdraws or otherwise loses his right to appraisal and payment under the GCL.
If, after the Effective Time, any such holder fails to perfect or withdraws or
loses his right to appraisal, such Dissenting Shares shall thereupon be treated
as if they had been converted as of the Effective Time into the right to receive
the Preferred Price Per Share or the Common Price Per Share, as the case may be,
if any, to which such holder is entitled, without interest or dividends thereon.
(b)     Each of Linfinity and Purchaser shall give the other prompt notice of
any demands received by Linfinity or Purchaser for appraisal of Shares and of
all negotiations and proceedings with respect to such demands.  After the
Effective Time, neither Linfinity nor Purchaser shall, except with the prior
written consent of SymmetriCom, make any payment with respect to, or settle or
offer to settle, any such demands.  SymmetriCom shall indemnify the Purchaser
and the Company from any costs and expenses of the Company incurred with respect
to appraisals or proceedings regarding Dissenting Shares and from any
incremental amount required to be paid to a shareholder over and above the
amount such shareholder is entitled to receive under this Agreement and the
Merger.

SECTION 2.02     Exchange of Certificates; Escrow
(a)     Prior to the Effective Time, Purchaser shall designate a bank or trust
company reasonably acceptable to Linfinity to act as paying agent (the "Paying
Agent") in effecting the exchange for the Preferred Price Per Share of
certificates (the "Preferred Certificates") that, prior to the Effective Time,
represented Preferred Stock, the Common Price Per Share of Certificates (the
"Common Certificates") that, prior to the Effective Time, represented Common
Stock, and the Option Price Per Share for Option Cancellation Certificates. Upon
the surrender of each Preferred Certificate formerly representing Preferred
Stock, together with a properly completed letter of transmittal, the Paying
Agent shall pay the holder of such Preferred Certificate the Preferred Price 

                                       5
<PAGE>
 
Per Share multiplied by the number of shares of Preferred Stock formerly
represented by each such Preferred Certificate, in exchange therefor, and each
such Preferred Certificate shall forthwith be canceled.  Until so surrendered
and exchanged, each such Preferred Certificate (other than Preferred
Certificates representing Dissenting Shares) shall represent solely the right to
receive the Preferred Price Per Share.  No interest shall be paid or accrue on
the Preferred Price Per Share.  If the Preferred Price Per Share (or any portion
thereof) is to be delivered to any person other than the person in whose name
the Preferred Certificate formerly representing shares of Preferred Stock
surrendered in exchange therefor is registered, it shall be a condition to such
exchange that the Preferred Certificate so surrendered shall be properly
endorsed or otherwise be in proper form for transfer and that the person
requesting such exchange shall pay to the Paying Agent any transfer or other
Taxes required by reason of the payment of the Preferred Price Per Share to a
person other than the registered holder of the Preferred Certificate
surrendered, or shall establish to the satisfaction of the Paying Agent that
such Tax has been paid or is not applicable.  Upon the surrender of each Common
Certificate formerly representing shares of Common Stock, together with a
properly completed letter of transmittal, the Paying Agent shall pay the holder
of such Common Certificate the Common Price Per Share multiplied by the number
of shares of Common Stock formerly represented by each such Common Certificate,
in exchange therefor, and each such Common Certificate shall forthwith be
canceled.  Until so surrendered and exchanged, each such Common Certificate
(other than Common Certificates representing Dissenting Shares) shall represent
solely the right to receive the Common Price Per Share.  No interest shall be
paid or accrue on the Common Price Per Share.  If the Common Price Per Share (or
any portion thereof) is to be delivered to any person other than the person in
whose name the Common Certificate formerly representing shares of Common Stock
surrendered in exchange therefor is registered, it shall be a condition to such
exchange that the Common Certificate so surrendered shall be properly endorsed
or otherwise be in proper form for transfer and that the person requesting such
exchange shall pay to the Paying Agent any transfer or other Taxes required by
reason of the payment of the Common Price Per Share to a person other than the
registered holder of the Common Certificate surrendered, or shall establish to
the satisfaction of the Paying Agent that such Tax has been paid or is not
applicable.  Upon the surrender of each Option Cancellation Certificate,
together with a properly completed letter of transmittal, the Paying Agent shall
pay the holder of such Option Cancellation Certificate the Option Price Per
Share multiplied by the number of shares of Common Stock formerly represented by
each such Option Cancellation Certificate, in exchange therefor.  Until so
surrendered and exchanged, each such Option Cancellation Certificate shall
represent solely the right to receive the Option Price Per Share.  No interest
shall be paid or accrued on the Option Price Per Share.  If the Option Price Per
Share (or any portion thereof) is to be delivered to any person other than the
person in whose name the Option Cancellation Certificate surrendered in exchange
therefor is registered, it shall be a condition to such exchange that the Option
Cancellation Certificate so surrendered shall be properly endorsed or otherwise
be in proper form for transfer and that the person requesting such exchange
shall pay to the Paying Agent any transfer or other Taxes required by reason of
the payment of the Option Price Per Share to a person other than the registered
holder of the Option Cancellation Certificate surrendered, or shall establish to
the satisfaction of the Paying Agent that such Tax has been paid or is not
applicable.

(b)     Prior to the Effective Time, Purchaser or Purchaser Sub shall deposit,
or cause to be deposited, in trust with the Paying Agent an amount equal to the
Purchase Price to which holders of Shares shall be entitled at the Effective
Time pursuant to Section 1.07 hereof; provided, however, that no such deposit
shall relieve Purchaser or Purchaser Sub of its obligation to pay the Purchase
Price pursuant to Section 1.07.  Notwithstanding the foregoing, $1,125,000 of
the consideration otherwise payable to SymmetriCom under this Section 2.02(b)
shall not be paid in cash at the Closing, but instead shall be held in escrow
pursuant to the Escrow Agreement attached hereto as Exhibit A (the "Escrow
Agreement").
(c)     The Purchase Price shall be invested by the Paying Agent as directed by
Purchaser, provided that such investments shall be limited to direct obligations
of the United States of America, obligations for which the full faith and credit
of the United States of America is pledged to provide for the payment of
principal and interest, commercial paper rated of the highest quality by Moody's
Investors Services, Inc. or Standard & Poor's Corporation, or certificates of
deposit issued by a commercial bank having at least $1,000,000,000 in assets;
provided further that no loss on investment made pursuant to this Section
2.02(c) shall relieve Purchaser or Purchaser Sub of its obligation to pay the
Purchase Price pursuant to Section 1.07.
(d)     Promptly after the Effective Time, the Paying Agent shall mail: (i) to
each record holder of Preferred Certificates that immediately prior to the
Effective Time represented Preferred Stock, a form of letter of transmittal and
instructions for use in surrendering such Preferred Certificates and receiving
the Preferred Price Per Share in exchange therefor and (ii) to each record
holder of Common Certificates that immediately prior to the Effective Time
represented Common Stock, a form of letter of transmittal and instructions for
use in surrendering such Common Certificates and receiving the Common Price Per
Share in exchange therefor.
(e)     After the Effective Time, there shall be no transfers on the stock
transfer books of the Surviving Corporation of any Shares.  If, after the
Effective Time, Common Certificates formerly representing Common Stock are
presented to the Surviving Corporation or the Paying Agent, they shall be
canceled and exchanged for the Common Price Per Share as provided in this
Article II, subject to applicable law in the case of Dissenting Shares.
(f)     Promptly following the date which is six (6) months after the Effective
Time, the Paying Agent shall deliver to Purchaser all cash and documents in its
possession relating to the transactions described in this Agreement, and the
Paying Agent's duties shall terminate.  Thereafter, each holder of a Common
Certificate formerly representing Common Stock may surrender such Common
Certificate to the Surviving Corporation and (subject to applicable abandoned
property, escheat and similar laws) receive in exchange therefor the Common
Price Per Share, without any interest thereon.

reasonably request. Purchaser will comply with the terms of the Confidentiality

SECTION 6.03     Reasonable Best Efforts.
(a)     Subject to the terms and conditions herein provided and to applicable
legal requirements, each of the parties hereto agrees to use its reasonable best
efforts to take, or cause to be taken, all action, and to do, or cause to be
done, and to assist and cooperate with the other parties hereto in doing, as
promptly as practicable, all things necessary, proper or advisable under
applicable laws and regulations to ensure that the conditions set forth in
Article VII are satisfied, to remove any injunctions or other impediments or
delays, legal or otherwise and to consummate and make effective the transactions
contemplated by this Agreement.
(b)     If at any time after the Effective Time any reasonable further action is
necessary or desirable to carry out the purposes of this Agreement, including
the execution of additional instruments, the proper officers and directors of
each party to this Agreement shall take all such necessary or desirable
reasonable action.

SECTION 6.04     Consents.
(a)     Each of the parties will use its reasonable best efforts to obtain as

(b)     Each of the Company and Purchaser shall use its reasonable best efforts
to file as soon as practicable notifications under the HSR Act and to respond as
promptly as practicable to any inquiries received from the Federal Trade
Commission and the Antitrust Division of the Department of Justice for
additional information or documentation and to respond as promptly as
practicable to all inquiries and requests received from any other Governmental
Entity in connection with antitrust matters.  The Purchaser (or the Purchaser
Sub) and the Company (or SymmetriCom) will each pay one-half of the filing fee
of the HSR notification.
(c)     In furtherance and not in limitation of the foregoing, each of Purchaser
and the Company shall use its reasonable best efforts to resolve such
objections, if any, as may be asserted with respect to the transactions
contemplated by this Agreement under any antitrust, competition or trade
regulatory laws, rules or regulations of any Governmental Entity ("Antitrust
Laws"); provided, however, that nothing in this Agreement shall require, or be
construed to require, Purchaser or any of its affiliates to proffer to, or agree
to, sell or hold separate and agree to sell, before or after the Effective Time,
any assets, businesses, or interest in any assets or businesses of Purchaser,
the Company or any of their respective affiliates (or to consent to any sale, or
agreement to sell, by the Company of any of its assets or businesses) or to
agree to any changes or restrictions in the operations of any such assets or
businesses.
(d)     Any party hereto shall promptly inform the others of any material
communication from the United States Federal Trade Commission, the Department of
Justice or any other governmental authority regarding any of the transactions
contemplated by this Agreement. If any party or any affiliate thereof receives a

government or authority with respect to the transactions contemplated by this
Agreement, then such party will endeavor in good faith to make, or cause to be
made, as soon as reasonably practicable and after consultation with the other
party, an appropriate response in compliance with such request. Purchaser will
advise the Company promptly in respect of any understandings, undertakings or
agreements (oral or written) which Purchaser proposes to make or enter into with
the Federal Trade Commission, the Department of Justice or any other domestic or
foreign government or governmental or multinational authority in connection with
the transactions contemplated by this Agreement.

SECTION 6.05     Public Announcements.  The mutual press release with respect to
the execution of this Agreement shall be a joint press release acceptable to
Purchaser, the Company and SymmetriCom. Thereafter, so long as this Agreement is
in effect prior to the Closing, neither Purchaser nor Purchaser Sub, on the one
hand, nor the Company nor any affiliate of the Company, on the other, shall
issue any press release or otherwise make any public statement with respect to
the transactions contemplated by this Agreement without prior consultation with
the other party, except as may be required by law (it being understood and
agreed that each of Purchaser and the Company's parent corporation, SymmetriCom,
intends to file a Current Report on Form 8-K with respect to the transaction
contemplated hereby promptly after the date hereof).

                                      30

SECTION 6.06     Notification of Certain Matters.  The parties shall promptly
notify each other of (a) the occurrence or non-occurrence of any fact or event
regarding such notifying party which would be reasonably likely (i) to cause any
representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect at any time from the date hereof to the
Effective Time or (ii) to cause any material covenant, condition or agreement
under this Agreement not to be complied with or satisfied in all material
respects and (b) any failure of the notifying party, as the case may be, to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it hereunder in any material respect; provided, however, that no
such notification shall affect the representations or warranties of any party or
the conditions to the obligations of any party hereunder.

SECTION 6.07     Acquisition Proposals.  Neither the Company nor any stockholder
shall (nor shall the Company permit any of its Affiliates to) directly or
indirectly, solicit, initiate or encourage any inquiries or the making of any
proposals from, engage or participate in any negotiations or discussions with,
provide any confidential information or data to, or enter into (or authorize)
any agreement or agreement in principle with any Person or announce any
intention to do any of the foregoing, with respect to any offer or proposal to
acquire all or any substantial part of the assets, properties, or the business
of the Company or the Shares, whether by merger, purchase of capital stock or
assets or otherwise (a "Competing Proposal"); provided, however, that at any
time prior to the approval of the Merger by the Company Stockholders', the
Company may furnish information to, and negotiate or otherwise engage in
discussions with, any party who delivers an unsolicited Competing Proposal to
the Company, if and so long as the Board of Directors of the Company determines
in good faith by a majority vote (after consultation with and receipt of written
advice from outside counsel which is consistent with such a determination) that
failing to take such action would constitute a breach of the fiduciary duties of
the Board of Directors of the Company under applicable Law.  The Company shall
immediately advise Purchaser, in writing, of any inquiry, offer or proposal
regarding a Competing Proposal and/or any determination by the Company's Board
of Directors with respect thereto, and shall keep Purchaser informed at all
times of the status thereof.

SECTION 6.08     Additional SymmetriCom Obligations.  In order to induce
Purchaser to enter into this Agreement, and as further consideration for the
promises and mutual covenants herein, SymmetriCom further represents, warrants
and covenants with Purchaser as follows:
(a)     Voting.  SymmetriCom will vote or cause to be voted all shares of
capital stock of the Company owned of record or beneficially owned or held in
any capacity by it or under its control in favor of the Merger and other
transactions provided for in or contemplated by this Agreement.
(b)     Restriction on Transfer.  SymmetriCom will not sell, transfer, pledge or
otherwise dispose of any of the Shares or any interest therein or agree to sell,
transfer, pledge or otherwise dispose of any of the Company or any interest
therein prior to Closing or the termination of this Agreement, without
Purchaser's express written consent.

SECTION 6.09     Certain Tax Matters

(a)     Liability for Taxes.

(i)     SymmetriCom shall be liable for all Taxes (A) imposed on the Company or
any corporation (other than the Company) that joins with SymmetriCom in filing a
combined or consolidated tax return (the "Company Tax Group") for any taxable
year, or (B) imposed on the Company or for which the Company may otherwise be
liable, for any taxable year or period that ends on or before the Closing Date
(including Income Taxes attributable to the Section 338(h) (10) Election) (a
"Pre-Closing Period") and, with respect to any period beginning prior to the
Closing Date and which does not terminate on the Closing Date (a "Straddle
Period"), the portion of such Straddle Period ending on and including the
Closing Date; provided, however, that SymmetriCom shall not be liable for and
shall not indemnify Purchaser for any (i) Taxes (other than Taxes attributable
to the Section 338(h) (10) Election) imposed on the Company as a result of
transactions (other than transactions in the ordinary course of business)
occurring on the Closing Date that are properly allocable to the portion of the
Closing Date after the Closing or (ii) any Taxes (other than income, franchise
or similar Taxes) reflected on the Current Balance Sheet or incurred in the
ordinary course of business since the Current Balance Sheet ((i) and (ii) being
referred to as "Excluded Taxes").  SymmetriCom shall be entitled to any refund
of Taxes for which it is liable pursuant to this paragraph (a) (i).

(ii)     Purchaser shall be liable for (A) all Taxes imposed on the Company, or
for which the Company may otherwise be liable, for any taxable year or period
that begins after the Closing Date (a "Post-Closing Period") and, with respect
to any Straddle Period, the portion of such Straddle Period beginning after the
Closing Date and (B) any Excluded Taxes.  Purchaser shall be entitled to any
refund of Taxes for which it is liable pursuant to this paragraph (a)(ii).

(iii)     For purposes of paragraphs (a)(i) and (a)(ii) of this Section 6.09,
whenever it is necessary to determine the liability for Taxes of SymmetriCom for
a portion of any Straddle Period, the determination of the Taxes of the Company
for the portion of the Straddle Period ending on and including, and the portion
of the Straddle Period beginning after, the Closing Date shall be determined by
assuming that the Straddle Period consisted of two taxable years or periods, one
which ended at the close of the Closing Date and the other which began at the
beginning of the day following the Closing Date, and items of income, gain,
deduction, loss or credit of the Company for the Straddle Period shall be
allocated between such two taxable years or periods on a "closing of the books
basis" by assuming that the books of the Company were closed at the close of the
Closing Date; provided, however, that (I)  Taxes imposed on the Company as a
result of transactions (other than transactions in the ordinary course of
business) occurring on the Closing Date that are properly allocable to the
portion of the Closing Date after the Closing shall be allocated to the taxable
year or period that is deemed to begin at the beginning of the day following the
Closing Date and (II) exemptions, allowances or deductions that are calculated
on an annual basis, such as the deduction for depreciation, shall be apportioned
between such two taxable years or

                                      32
<PAGE>
 
periods on a daily basis.  For purposes of paragraphs (a)(i) and (a)(ii) of this
Section 6.09, whenever it is necessary to determine the liability for Taxes
(other than Excluded Taxes) attributable to real or personal property Taxes of
the Company for a portion of any Straddle Period, the total amount of such Taxes
for the period in question shall be multiplied by a fraction, the numerator of
which is the number of days of the Straddle Period that are in the Pre-Closing
Period and the denominator of which is the total number of days in the Straddle
Period; provided, however, that any amount of Straddle Period Taxes attributable
to the increase in the assessed value of real or personal property as a result
of the transactions contemplated by this Agreement shall be borne by Purchaser.

(iv)     For purposes of paragraphs (a) (i) and (a) (ii) of this Section 6.09
whenever it is necessary to allocate an item of income, gain, deduction, loss or
credit to either a taxable year or period that ends on or before the Closing
Date or a taxable year or period that begins after the Closing Date, rules
consistent with those in Treas. Reg. (S) 1.1502-76(b) shall be applied.

(v)     If, as a result of any action, suit, investigation, audit, claim,
assessment or amended Tax Return, there is any change after the Closing Date in
an item of income, gain, loss, deduction or credit that results in an increase
in an Income Tax liability for which SymmetriCom would otherwise be liable
pursuant to paragraph (a) (i) of this Section 6.09, and such change results in a
decrease in the Income Tax liability of the Company, Purchaser, or any Affiliate
or successor thereof for any taxable year or period beginning after the Closing
Date or for the portion of any Straddle Period beginning after the Closing Date,
SymmetriCom shall not be liable pursuant to such paragraph (a) (i) with respect
to such increase to the extent of such decrease.  If, as a result of any action,
suit, investigation, audit, claim, assessment or amended Income Tax Return,
there is any change after the Closing Date in an item of income, gain, loss,
deduction or credit that results in an increase in an Income Tax liability for
which Purchaser would otherwise be liable pursuant to paragraph (a) (ii) of this
Section 6.09, and such change results in a decrease in the Income Tax liability
of SymmetriCom or any Affiliate or successor thereof (other than the Company)
for any taxable year or period ending on or before the Closing Date or for the
portion of any Straddle Period ending on the Closing Date (other than by reason
of a carryback of losses or deductions), Purchaser shall not be liable pursuant
to such paragraph (a) (ii) with respect to such increase to the extent of such
decrease.

(vi)     Purchaser shall pay all Transfer Taxes.  For purposes of this
Agreement, "Transfer Taxes" means all stamp, recordation, sales, use, real
property transfer or gains or similar transfer Taxes attributable to the actual
or deemed transfer of property or stock from SymmetriCom or the Company to
Purchaser or the Company, together with any penalties or interest with respect
to such taxes.

(vii)     On or prior to the Closing Date, all Tax Sharing Arrangements (other
than this Agreement) between the Company, on one hand, and SymmetriCom or any
member of the Company Tax Group, on the other hand, shall terminate and the
Company shall not have any further rights or obligations thereunder.  For
purposes of this paragraph, a "Tax Sharing

                                      33
<PAGE>
 
Arrangement" shall mean any agreement or arrangement for the allocation or
payment of Tax liabilities or payment for Tax benefits with respect to a
consolidated, combined or unitary Tax Return which Tax Return includes the
Company.

(b)     Tax Returns.

(i)     SymmetriCom shall file or cause to be filed when due all Tax Returns
that are required to be filed by or with respect to the Company for taxable
years or periods ending on or before the Closing Date and which relate to Taxes
for which SymmetriCom is liable pursuant to Section 6.09(a)(i) and shall remit
any Taxes due in respect of such Tax Returns, and Purchaser shall file or cause
to be filed when due all Tax Returns that are required to be filed by or with
respect to the Company for taxable years or periods ending after the Closing
Date and shall remit any Taxes due in respect of such Tax Returns.  Any Tax
Returns required to be filed by Purchaser pursuant to this Section 6.09 relating
in whole or in part to Taxes for which SymmetriCom is liable pursuant to
paragraph (a)(i) of this Section 6.09 shall be submitted to SymmetriCom for
SymmetriCom's approval (which approval shall not be unreasonably withheld) prior
to Purchaser filing such Tax Returns.  SymmetriCom or Purchaser shall reimburse
the other party for the Taxes for which SymmetriCom or Purchaser is liable
pursuant to paragraphs (a)(i) and (ii) of this Section 6.09 but which are
payable with Tax Returns to be filed by the other party pursuant to the second
preceding sentence upon the written request of the party entitled to
reimbursement, setting forth in detail the computation of the amount owed by
SymmetriCom or Purchaser, as the case may be, but in no event earlier than ten
(10) days prior to the due date for the payment of such Income Taxes.

(ii)     With respect to the period prior to the Closing Date, Purchaser shall
promptly cause the Company to prepare and provide to SymmetriCom a package of
tax information materials, including, without limitation, schedules and work
papers (the "Tax Package"), required by the Company to enable the Company to
prepare and file all Income Tax Returns required to be prepared and filed by it
pursuant to paragraph (b) of this Section 6.09.  The Tax Package shall be
completed in accordance with past practice, including past practice as to
providing such information, and as to the method of computation of separate
taxable income or other relevant measure of income of the Company.  SymmetriCom
shall cooperate with any reasonable request for information by Purchaser or the
Company made in connection with the preparation of the Tax Package.  Purchaser
shall cause the Tax Package to be delivered to SymmetriCom within ninety (90)
days after the Closing Date.

(c)     Contest Provisions.

(i)     Purchaser shall promptly notify SymmetriCom in writing upon receipt by
Purchaser, any of its Affiliates or the Company of notice of any pending or
threatened federal, state, local or foreign Tax audits, examinations or
assessments which may affect any Income Tax liability for which SymmetriCom is
liable pursuant to paragraph (a)(i) of this Section 6.09, provided that failure
to comply with this provision shall not affect Purchaser's right to
indemnification

                                      34
<PAGE>
 
hereunder except to the extent such failure materially impairs SymmetriCom's
ability to contest any such Income Tax liabilities.

(ii)     SymmetriCom shall have the sole right to represent the Company's
interests in any Income Tax audit or administrative or court proceeding relating
to taxable periods ending on or before the Closing Date, and to employ counsel
of its choice at its expense.  In the case of any Straddle Period, SymmetriCom
shall be entitled to participate at its expense in any Tax audit or
administrative or court proceeding relating (in whole or in part) to Taxes
attributable to the portion of such Straddle Period ending on and including the
Closing Date and, with the written consent of Purchaser, and at SymmetriCom's
sole expense, may assume the entire control of such audit or proceeding.
Purchaser and SymmetriCom each agrees not to (and Purchaser shall cause its
Affiliates, including, after the Closing Date, the Company, and the Company
shall cause its Affiliates, not to) agree to settle any Tax claim which may be
the subject of indemnification by the other party pursuant to Section 6.09
without the prior written consent of the indemnifying party (which consent shall
not be unreasonably withheld).

(d)     Assistance and Cooperation.  After the Closing Date, each of SymmetriCom
and Purchaser shall (and cause their respective Affiliates to):

(i)     assist the other party in preparing any Tax Returns which such other
party is responsible for preparing and filing in accordance with paragraph (b)of
this Section 6.09;

(ii)     cooperate fully in preparing for any audits of, or disputes with taxing
authorities regarding, any Tax Returns of the Company.

(iii)     make available to the other for inspection and duplication and to any
taxing authority as reasonably requested all information, records, and documents
relating to Taxes of the Company and shall maintain such information, records
and documents for a period of 15 years from the Closing Date.

(iv)     provide timely notice to the other in writing of any pending or
threatened Tax audits or assessments of the Company for taxable periods for
which the other may have a liability under this Section 6.09; and

(v)     furnish the other with copies of all correspondence received from any
taxing authority in connection with any Tax audit with respect to any taxable
period for which the other may have a liability under this Section 6.09.

(e)     Election Under Section 338(h)(10).

(i)     SymmetriCom and Purchaser shall make a joint election for the Company
under Section 338(h)(10) of the Code with respect to the purchase of the Company
capital

                                      35
<PAGE>
 
stock effected by the Merger (the "Section 338(h)(10) Election") together with
any corresponding elections under state and local tax laws.  SymmetriCom and
Purchaser shall within ninety (90) days of the Closing exchange completed and
executed copies of Internal Revenue Service Form 8023, any required schedules
thereto, and any similar state forms.  If any changes are required in these
forms as a result of information which is first available after the Closing
Date, the parties will promptly agree on such changes.

(ii)     At the Closing, Purchaser and SymmetriCom shall agree on a written
schedule (the "Allocation Schedule") allocating the Modified Adjusted Deemed
Sales Price, as defined in Treas. Reg. (S) 1.338(h) (10)-1(f), for the Company,
among the assets of the Company. The Allocation Schedule shall be reasonable and
shall be prepared in accordance with Section 338(h)(10) of the Code and the
regulations thereunder.  Purchaser and SymmetriCom each agrees to file (and to
cause their respective Affiliates to file) all federal, state, local and foreign
Tax Returns consistent with the Allocation Schedule.

(f)     FIRPTA Certificate.  At or prior to the Closing, the Company shall
provide Purchaser with a certificate described in Treas. Reg. (S) 1.1445-2(b)
(2) to the effect that, as contemplated by such certificate, SymmetriCom is not
a foreign corporation, foreign partnership, foreign trust or foreign estate (as
those terms are defined in the Code and Treasury Regulations).

(g)     References to Company.  References in this Section 6.09 to the Company
shall mean, with respect to any period after the Effective Time, the Surviving
Corporation.

(h)     Treatment of Transaction.  SymmetriCom and Purchaser shall, and shall
cause their respective Affiliates to, treat the Merger for all Tax purposes as a
purchase by Purchaser from SymmetriCom of the Company's capital stock.

(i)     Adjustment to Purchase Price.  Any payment by Purchaser or SymmetriCom
to the other party under this Section 6.09 will be deemed to be an adjustment to
the Purchase Price.

SECTION 6.10     Linfinity Audited Financials.  Within sixty (60) days of the
Closing, SymmetriCom will at its expense and using its current auditors provide
to Purchaser audited financial statements for Linfinity for the three year
period ended on June 30, 1998.  Following the Closing Microsemi and Linfinity
will provide SymmetriCom and its auditors with full access to the books and
records of Linfinity for purposes of completion of the audited financials under

indefinitely.

(b)     The representations and warranties of SymmetriCom in Article IV (other

(a)     SymmetriCom shall indemnify, defend and hold harmless Purchaser, its
subsidiaries, including but not limited to the Surviving Corporation, and their
respective officers, directors, employees and agents (collectively, the
"Purchaser Indemnified Persons") against all claims, demands, actions,
obligations, suits, fines, losses, liabilities, damages, deficiencies, costs and

                                      41
<PAGE>
 
(hereinafter individually a "Loss" and collectively "Losses") incurred by the
Purchaser Indemnified Persons and arising out of or relating to:

(i)     any inaccuracy or breach by SymmetriCom and/or Linfinity of any
representation or warranty made by it under Article III of this Agreement,
except as set forth in Section 9.02(c) below;

(collectively, the "SymmetriCom Indemnified Persons") against any Loss or Losses
as defined in Section 9.02(a) incurred by any of them arising out of or relating

(i)     with respect to any remedial actions which are required or otherwise

Review dated August 20, 1997 by Ehrlich-Rominger ("H6 Report"), the parties
acknowledge that the Purchase Price has been negotiated with the full
understanding of the matters raised in the H6 Report ("H6 Report Remedial

respect to or otherwise arising out of the H6 Report or H6 Report Remedial
Actions (including, without limitation, any Third Party Claims of any kind or
nature, as defined hereinafter, arising out of SymmetriCom's failure to complete
any or all of the H6 Report Remedial Actions prior to the

                                      42

Purchaser's failure to complete such H6 Report Remedial Actions after the
Closing; and

(ii)    with respect to Section 3.15 and environmental representations set

reviewed that certain report entitled Soil and Groundwater Investigations
Conducted at the Facilities Located at 11861 Western Avenue and 11652 Markon
Drive, Garden Grove, California prepared by URS Greiner Woodward Clyde and dated
January 27, 1999, and that certain Contingent Environmental Liability Report
dated January 25, 1999 by EQQUA (the "Phase II Site and Liability Assessments")
and Purchaser agrees that based on Purchaser's and its consultant's review of
the Phase II Site and Liability Assessments, SymmetriCom's liability for any
violations of the representations set forth in Section 3.15 or any other
environmental representations set forth in Article III shall be limited to the
$128,000.  SymmetriCom shall not have any liability in excess of that provided
for in this Section 9.02(c)(ii) for any violations of the representations set
forth in Section 3.15 or any other environmental representations set forth in
Article III.

SECTION 9.03     Notification and Defense of Claims.

(a)     Notification.  Other than with respect to claims for indemnification
under Section 6.09 (which Section 6.09 claims shall be treated as provided for
therein), the "Indemnified Persons" (referred to hereinafter as the Purchaser
Indemnified Persons or the SymmetriCom Indemnified Persons, as the case may be)
will give written notice to the "Indemnitors" (referred to hereinafter as
SymmetriCom, in the case of indemnifications pursuant to Section 9.02(a)(i),
(ii) or (iii) and Purchaser, in the case of indemnifications pursuant to Section
9.02(b)(i) or (iii)) of any claim for Losses for which the Indemnified Persons
claim a right of indemnification under Section 9.02 (an "Indemnification
Notice"); provided, however, that if the Indemnified Persons have received from
any  third party actual notice of any actual or threatened demand, claim,
action, suit, proceeding or investigation by such third party (a "Third Party
Claim"), then the Indemnified Persons shall provide the Indemnification Notice
to the Indemnitors within ten (10) days of receiving such actual notice; and
provided, further, that no failure to so notify the Indemnitors of a Third Party
Claim will relieve the Indemnitees of any obligation to indemnify the
Indemnified Persons unless and except to the extent that such failure to so
notify prejudices the position of the Indemnitors in responding to such Third
Party Claim.  The Indemnification Notice shall include:

(i)     A summary description of the facts giving rise to any indemnification
provided for in Section 9.02 (with such material detail and documents related
thereto as are then reasonably available to the Indemnified Persons), and will
specify the estimated amount of the Loss for which indemnification is claimed,
to the extent known to the Indemnified Persons; and

(ii)    If the facts giving rise to any indemnification provided for in Section
9.02 involve a Third Party Claim, then the Indemnified Persons shall indicate
whether they have elected  (1) to tender to the Indemnitors the defense of such
Third Party Claim through counsel

                                      43
<PAGE>
 
of the Indemnitors' own choosing, subject to the terms of Section 9.03(d) or
9.03(e), as the case may be, or (2) to assume the defense of any such Third
Party Claim through counsel of the Indemnified Persons' own choosing.

(b)     Response.  The Indemnitors will have twenty (20) days following delivery
of the Indemnification Notice to make such investigation of the claim as they
deem necessary or desirable.  On or prior to the expiration of such 20-day
period, the Indemnitors will, by written notice to the Indemnified Persons (a
"Response Notice"):

(i)     Either (1) admit liability in whole, (2) admit that the claim is so
covered by Section 9.02 but dispute the amount of the claim, or (3) dispute that
any amount of the claim is so covered; and

(ii)    If the defense of a Third Party Claim has been tendered to the
Indemnitors pursuant to Section 9.03(a)(ii), indicate whether the Indemnitors
will assume or decline the tendered defense.

The failure of the Indemnitors to deliver to the Indemnified Persons a timely
Response Notice in accordance with this Section 9.03(b) will be deemed an
admission of liability for the entire Loss as set forth in the Indemnification
Notice and a decline to assume the tendered defense of a Third Party Claim, if
such defense has been tendered.

(c)     Indemnity Disputes.  If the Indemnitors deliver to the Indemnified
Persons a timely Response Notice pursuant to Section 9.03(b) disputing the
amount of the claim or disputing that the claim is covered by Section 9.02, or
if any other dispute arises with respect to this Article IX, then the
Indemnitors and the Indemnified Persons will use their best efforts to resolve
such dispute.  In the event the Indemnitors and the Indemnified Persons resolve
the dispute, they will both execute a memorandum setting forth such resolution
and, if applicable, the amount of any Loss payable to the Indemnified Persons.
In the event the Indemnitors and the Indemnified Persons are unable to resolve
such dispute within thirty (30) days from the Indemnified Persons' receipt of
the Response Notice pursuant to Section 9.03(b), the Indemnitors and the
Indemnified Persons will be entitled to initiate legal proceedings in order to
resolve such dispute.

(d)     Defense by Indemnitors.  If the defense of a Third Party Claim is
tendered by the Indemnified Persons to the Indemnitors pursuant to Section
9.03(a)(ii) and is subsequently assumed by the Indemnitors, the Indemnified
Persons will be entitled, at their own expense, to participate in such
settlement or defense through counsel chosen by the Indemnified Persons.  If the
Indemnitors assume the defense of the Third Party Claim, they will take all
steps reasonably necessary in the defense or settlement of the Third Party Claim
and will hold the Indemnified Persons harmless from and against all Losses
(other than the Indemnified Persons' expenses of participation in such defense
or settlement) caused by or arising out of any settlement thereof or any
judgment in connection therewith.  The Indemnitor may not, in the defense of any
Third Party Claim they assume, except

                                      44
<PAGE>
 
with the written consent of the Indemnified Persons, consent to the entry of any
judgment or enter into any settlement (i) which does not include as an
unconditional term thereof the giving to the Indemnified Persons by the third
party of a full and final release from all liability in respect of such Third
Party Claim, (ii) which will limit, restrict or otherwise affect the right of
the Indemnified Persons to carry on or conduct business (then or in the future),
or require any payment to be made by the Indemnified Persons or limit, restrict,
make more expensive or less profitable or otherwise adversely affect the manner
in which the Indemnified Persons carry on or conduct business (then or in the
future) or (iii) under which the amount of settlement or judgment against the
Indemnified Persons exceeds the amount of indemnification for such Third Party
Claim then available to the Indemnified Persons from the Indemnitors.

(e)     Defense by Indemnified Persons.  If the Indemnitors do not assume the
defense of a Third Party Claim within the 20-day period required by Section
9.03(b), or if the Indemnified Persons assume the defense of any such Third
Party Claim pursuant to Section 9.03(a)(ii)(2), then the Indemnified Persons may
defend such Third Party Claim in such manner as they may deem appropriate, in
which case legal expenses of the Indemnified Persons' counsel and all other
expenses incurred in such defense will be promptly paid by the Indemnitors as
receipts, invoices or other reasonable evidence of such expenses are presented
to the Indemnitees.  In such case, the Indemnified Persons may settle such Third
Party Claim on such terms as the Indemnified Persons reasonably deem
appropriate, and the Indemnitors will promptly pay the Indemnified Persons for
the Losses incurred as a result of such settlement for which the Indemnified
Persons are entitled to be indemnified.  If no such settlement of such Third
Party Claim is made, the Indemnitors will promptly pay the Indemnified Persons
for the Losses arising out of any judgment rendered with respect to such Third
Party Claim; provided, however, that if such judgment is appealable and the
Indemnified Persons notify the Indemnitors of their intention not to appeal, the
Indemnitors may prosecute such appeal, at their sole cost and expense, subject
to the terms set forth in this Article IX.  Notwithstanding anything in this
Article IX to the contrary, (i) the Indemnitors shall not be responsible for the
fees, costs or expenses of the Indemnified Persons in excess of such fees, costs
or expenses which are reasonable, and (ii) if the Indemnified Persons elect to
assume the defense of any Third Party Claim without first tendering the defense
of such Third Party Claim to the Indemnitees under Section 9.03(a)(ii), and if
the Indemnified Persons then enter into a settlement or consent to a judgment in
respect of such Third Party Claim without the approval of the Indemnitors (which
approval will not unreasonably be withheld), then the amount of such settlement
or judgment shall not be determinative of the amount of the Loss against which
the Indemnified Persons are entitled to indemnification under this Article IX.
In connection with any settlement entered into by the Indemnified Persons and
approved by the Indemnitees, the Indemnified Persons shall grant to the
Indemnitors an unconditional release in connection with the specific Losses to
which such settlement relates, contingent upon payment by the Indemnitors of the
amounts required by this Article IX (which amounts shall be specified in such
release).

SECTION 9.04     Order of Payment; Exclusion and Limitation of Liability.
Notwithstanding the foregoing Sections 9.01 through 9.03, the following
provisions shall apply in the event the Purchaser Indemnified Persons incur any
Losses covered by Section 9.02.

(a)     Payment for Breach of SymmetriCom and Linfinity Representations and
Warranties.  With respect to Losses arising in connection with Article III
(other than Sections 3.01, 3.03 and 3.04) and Section 9.02(a)(i) of this
Agreement, and subject to Section 9.02(c), the amount of any Loss against which
the Purchaser Indemnified Persons are entitled to indemnification under Section
9.02(a)(i) shall be limited to the Escrow Fund amount of $1,125,000 (as defined
under the Escrow Agreement) and shall be made under the terms of the Escrow
Agreement.

(b)     De Minimus Losses.  The Purchaser Indemnified Persons shall not be
entitled to make a claim for indemnification under Section 9.02(a)(i) until the
amount of Losses suffered by the Purchaser Indemnified Persons exceeds $100,000.
If the threshold amount is reached, the Purchaser Indemnified Persons may
recover the full amount of Losses, including the threshold amount.

(c)     Limitation of Liability.  In no case shall SymmetriCom be required to
provide indemnification under this Agreement in an amount in excess of the
amount of cash consideration it is entitled to receive under this Agreement;
provided, however that such limitation shall not apply in the case of actual
fraud by SymmetriCom.

(d)     Non-Exclusion of Amounts Below Material Adverse Effect.  In no event
shall the presence of any qualification of a representation or warranty with the
term "Material Adverse Effect" limit SymmetriCom's liability with respect to
indemnifying against the entire amount of Loss otherwise provided for in this
Agreement, including the portion which by itself would not constitute a
"Material Adverse Effect."

SECTION 9.05     General.

(a)     For purposes of this Article IX, Purchaser shall be agent and attorney-
in-fact (the "Purchaser Indemnified Persons' Agent") for each Purchaser
Indemnified Person, to give and receive notices and communications, to request
delivery to Purchaser Indemnified Persons of monies subject to the Escrow
Agreement or otherwise due to the Purchaser Indemnified Persons hereunder, to

legal proceedings and comply with orders or awards in any such proceeding, and
to take all other actions necessary or appropriate in the judgment of the

Persons with respect to the matters subject to this Article IX or the Escrow
Agreement.  No bond shall be required of the Purchaser Indemnified Persons'
Agent, and the Purchaser Indemnified Persons' Agent shall not receive
compensation for its services.  Notices or communications to or from the
Purchaser Indemnified Persons' Agent shall constitute notice to or from each of
the Purchaser Indemnified Persons.  A decision, act, consent or instruction of
the Purchaser Indemnified Persons' Agent shall constitute the decision, act,
consent or instruction of all

                                      46
<PAGE>
 
the Purchaser Indemnified Persons and shall be final, binding and conclusive
upon each of such Purchaser Indemnified Persons, and SymmetriCom and the Escrow
Agent (as such term is defined in the Escrow Agreement) may rely upon any such
decision, act, consent or instruction of the Purchaser Indemnified Persons'
Agent as being the decision, act, consent or instruction of each Purchaser
Indemnified Person, notwithstanding any notice to the contrary from any
Purchaser Indemnified Person.  SymmetriCom and the Escrow Agent are hereby

Agent shall not receive compensation for its services.  Notices or
communications to or from the SymmetriCom Indemnified Persons' Agent shall
constitute notice to or from each of the SymmetriCom Indemnified Persons.  A
decision, act, consent or instruction of the SymmetriCom Indemnified Persons'
Agent shall constitute the decision, act, consent or instruction of all the
SymmetriCom Indemnified Persons and shall be final, binding and conclusive upon
each of such SymmetriCom Indemnified Persons, and Purchaser and the Escrow Agent
(as such term is defined in the Escrow Agreement) may rely upon any such
decision, act, consent or instruction of the SymmetriCom Indemnified Persons'
Agent as being the decision, act, consent or instruction of each SymmetriCom
Indemnified Person, notwithstanding any notice to the contrary from any
SymmetriCom Indemnified Person.  Purchaser and the Escrow Agent are hereby
relieved from any liability to any SymmetriCom Indemnified Person for any acts

<PAGE>
 
(a)     the term "Affiliate," as applied to any person, shall mean any other
person directly or indirectly controlling, controlled by, or under common
control with, that person. For the purposes of this definition, "control"
(including, with correlative meanings, the terms "controlling," "controlled by"
and "under common control with"), as applied to any person, means the
possession, directly or indirectly, of the power to direct or cause the
direction of the management and policies of that person, whether through the
ownership of voting securities, by contract or otherwise;

(b)     the term "Person" shall include individuals, corporations, partnerships,

respect to Purchaser, the Company or any other person, any corporation,
partnership, joint venture or other legal entity of which Purchaser, the Company

                   (To Agreement and Plan of Reorganization)

                               ESCROW AGREEMENT

In order to designate Southern California Bank as the escrow agent (the "Escrow
Agent") of the undersigned for the purposes and upon the terms and conditions
herein set forth, SymmetriCom Inc., a California corporation ("SymmetriCom"),
and Microsemi Corporation, a Delaware corporation ("Microsemi"), do hereby enter
into this Escrow Agreement effective as of ____________, 1999.

1.     Appointment.  The Escrow Agent is hereby appointed escrow agent for the
undersigned with respect to the Escrow Fund as that term is herein defined.  The
Escrow Fund is established pursuant to Section 2.02(b) of the Agreement and Plan
of Reorganization dated February 10, 1999 (the "Merger Agreement") by and among
Microsemi, SymmetriCom and their respective subsidiaries. Capitalized terms used
herein and not otherwise defined shall have the same meaning ascribed to them in
the Merger Agreement.

2.     The Escrow Fund.  Concurrently with the execution and delivery hereof,
Microsemi and SymmetriCom have delivered to the Escrow Agent in accordance with
the terms hereof the amount of one million one hundred twenty-five thousand
dollars ($1,125,000) (the "Escrow Fund") and direct that it be held and disposed
of by the Escrow Agent as herein provided.

3.     Escrow Agent's Duties and Authority to Act.

(a)     The provisions of the Merger Agreement addressing the Escrow Fund
created hereby, the powers of the Purchaser Indemnified Persons' Agent
(sometimes referred to hereinafter as "Purchaser"), the powers of the
SymmetriCom Indemnified Persons' Agent (sometimes referred to hereinafter as
"SymmetriCom") and the resolution of disputes relating to the Escrow Fund
between the Purchaser Indemnified Persons and the SymmetriCom Indemnified Person
are attached hereto as Exhibit A.  The Escrow Agent is not a party to, and is
not bound by, or charged with notice of, any agreement out of which this escrow
may arise, except that the Escrow Agent shall be charged with notice of and be
bound by the provisions of the Merger Agreement attached hereto as Exhibit A.
<PAGE>
 
(b)     The Escrow Agent is hereby authorized and directed to deliver the Escrow
Fund, or any portion thereof, only at such times, in such amounts and upon such
terms and conditions as directed in writing by both the Purchaser and
SymmetriCom.

(c)     Notwithstanding the foregoing, if the Escrow Agent has not received any
notice of claim against the Escrow Fund from the Purchaser on or before the
first anniversary of the effective date of this Escrow Agreement (except that
notices of claims with respect to Sections 3.01, 3.03, 3.04, 3.05, 3.11, 3.13,
3.22, 4.02 and 4.03 may be made on or before the second anniversary of the
effective date of this Escrow Agreement), the Escrow Agent shall remit within
three (3) business days of such second anniversary of the effective date of this
Escrow Agreement the entire Escrow Fund to SymmetriCom, without further action
by any party.

4.      Standards of Care; Indemnification of Escrow Agent.  In performing any
duties under this Escrow Agreement, the Escrow Agent shall not be liable to any
party for consequential damages, (including, without limitation, lost profits)
losses, or expenses, except for breach of this Escrow Agreement, gross
negligence or willful misconduct on the part of the Escrow Agent.  The Escrow
Agent shall not incur any such liability for any act or failure to act made or
omitted in good faith, or any action taken or omitted in reliance upon any
instrument, including any written statement or affidavit provided for in this
Escrow Agreement that the Escrow Agent shall in good faith believe to be
genuine, nor will the Escrow Agent be liable or responsible for forgeries,
fraud, impersonations, or determining the scope of any representative authority.
In addition, the Escrow Agent may consult with legal counsel in connection with
the Escrow Agent's duties under this Escrow Agreement and shall be fully
protected in any act taken, suffered, or permitted by him/her in good faith in
accordance with the advice of legal counsel.  The Escrow Agent is not
responsible for determining and verifying the authority of any person acting or
purporting to act on behalf of any party to this Escrow Agreement.  The parties
and their respective successors and assigns agree jointly and severally to
indemnify and hold the Escrow Agent harmless against any and all losses, claims,
damages, liabilities, and expenses, including reasonable costs of investigation,
counsel fees, including allocated costs of in-house counsel and disbursements
that may be imposed on or incurred by the Escrow Agent in connection with the
performance of his/her duties under this Escrow Agreement, including but not
limited to any litigation arising from this Escrow Agreement or involving its
subject matter.  The Escrow Agent shall have a first lien on the property and
papers held under this Escrow Agreement for such compensation and expenses.
However, any such lien shall not in any way modify the responsibilities between
SymmetriCom and Purchaser hereunder.

5.      Investments.

(a)     For the purpose of investing funds held in the Escrow Fund, the Escrow
Agent may accept written instructions (including instructions sent to the Escrow
Agent by facsimile transmission, with original sent promptly to the Escrow
Agent) from SymmetriCom, provided that such investments shall be limited to
short term instruments of 90 days or less with maturity not in any event to be
beyond the anniversary of the date of the term of this Escrow Agreement and
further

                                       2
<PAGE>
 
limited to direct obligations of the United States of America, obligations for
which the full faith and credit of the United States of America is pledged to
provide for the payment of principal and interest, commercial paper rated of the
highest quality by Moody's Investors Services, Inc. or Standard & Poor's
Corporation, or certificates of deposit issued by a commercial bank having at
least $1,000,000,000 in assets; provided further that no loss on investment made
pursuant to this Section 5 shall relieve SymmetriCom of its obligation to
indemnify the Purchaser Indemnified Persons in accordance with Article IX of the
Merger Agreement.  The parties shall indemnify and hold the Escrow Agent
harmless from any and all liability for acting on such investment instruction
purported to be given by SymmetriCom.  The Escrow Agent shall not be responsible
for the authenticity of any instructions, or be in any way liable for any
unauthorized instruction.  In no event shall the Escrow Agent be liable to the
parties for any consequential, special, or exemplary damages, including but not
limited to lost profits, from any cause whatsoever arising out of, or in any way
connected with acting upon instructions believed by the Escrow Agent to be
genuine.

(b)     The Escrow Agent may make any investments through its own investment
department or that of its affiliates.  The Escrow Agent shall not be liable for
any loss from such investments, including upon the sale or disposition of any
investments.

(c)     The Escrow Agent will act upon investment instructions the day that such
instructions are received, provided the requests are communicated within a
sufficient amount of time to allow the Escrow Agent to make the specified
investment.  Instructions received after an applicable investment cutoff
deadline will be treated as being received by the Escrow Agent on the next
business day, and the Escrow Agent shall not be liable for any loss arising
directly or indirectly, in whole or in part, from the inability to invest funds
on the day the instructions are received.  The Escrow Agent shall not be liable
for any loss incurred by the actions of third parties or by any loss arising by
error, failure, or delay in making an investment which is caused by
circumstances beyond the Escrow Agent's reasonable control.

(d)     The Parties acknowledge that payment of any interest earned on the funds
invested in this escrow will be subject to backup withholding penalties unless a
properly completed Internal Revenue Service form W8 and W9 certification is
submitted to the Escrow Agent.

6.      Income. Any net income received by the Escrow Fund shall be disbursed to
SymmetriCom within ten (10) days of the end of each calendar quarter, and shall
not be deemed a part of the "Escrow Fund" hereunder.

7.      Termination.  This Escrow Agreement shall terminate without further
action of any party when all of the terms hereof have been fully performed,
whereupon the Escrow Agent's obligations hereunder shall terminate.

8.      Fees.

                                       3
<PAGE>
 
(a)     The Escrow Agent shall be entitled to the fees described on the Fee
Schedule attached hereto as Exhibit B (the "Fee Schedule").  It is understood
that the fees and usual charges agreed upon for services of the Escrow Agent
shall be considered compensation for ordinary services as contemplated by this
Escrow Agreement.  In the event that the conditions of this Escrow Agreement are
not promptly fulfilled, or if the Escrow Agent renders any service not provided
for in this Escrow Agreement at the request of the parties or as reasonably
determined to be necessary by the Escrow Agent, or if the parties request a
substantial modification of its terms, or if any controversy arises, or if the
Escrow Agent is made a party to, or intervenes in, any litigation pertaining to
this escrow or its subject matter, the Escrow Agent shall be reasonably
compensated for such extraordinary services and reimbursed for all costs,
attorney's fees, including allocated costs of in-house counsel, and expenses
occasioned by such default, delay, controversy or litigation and the Escrow
Agent shall have the right to retain all documents and/or other things of value
at any time held by the Escrow Agent in this escrow until such compensation,
fees, costs, and expenses are paid. The parties jointly and severally promise to
pay these sums upon demand and agree that the Escrow Agent may deduct such sums
from the Escrow Fund (it being understood that this sentence is for the benefit
of the Escrow Agent, and does not affect any agreement between SymmetriCom and
Purchaser as to the allocation of such expenses).

(b)     In the case of all fees payable under Section 8(a), responsibility shall
be split equally between Microsemi and SymmetriCom.

9. Dispute.  In the event any dispute arises as to payment of funds from the
Escrow Fund:

  (a)        funds in excess of the disputed amount, if any, less amounts
withheld pursuant to the terms of Section 8 hereof, shall be released to
SymmetriCom in accordance with the terms of this Escrow Agreement; and

  (b)        the remaining funds subject to a claim by the Purchaser Indemnified
Persons shall continue to be held in escrow until the claim or claims have been
fully resolved by agreement between the Purchaser Indemnified Persons and
SymmetriCom.

  (c)        If any controversy arises between the parties to this Escrow
Agreement, or with any other party, concerning the subject matter of this Escrow
Agreement, its terms or conditions, the Escrow Agent will not be required to
determine the controversy or to take any action regarding it.  The Escrow Agent
may hold all documents and funds and may wait for settlement of any such
controversy by final appropriate legal proceedings or other means as, in the
Escrow Agent's discretion, the Escrow Agent may require, despite what may be set
forth elsewhere in this Escrow Agreement.  In such event, the Escrow Agent will
not be liable for interest or damage.  Furthermore, the Escrow Agent may at its
option, file an action of interpleader requiring the parties to answer and
litigate or arbitrate any claims and rights among themselves.  The Escrow Agent
is authorized to deposit with the clerk of the court all documents and funds
held in escrow, except all costs, expenses,

                                       4
<PAGE>
 
charges and reasonable attorney fees incurred by the Escrow Agent due to the
interpleader action and which the Parties jointly and severally agree to pay.
Upon initiating such action, the Escrow Agent shall be fully released and
discharged of and from all obligations and liability imposed by the terms of
this Escrow Agreement.

10.     Resignation of Escrow Agent; Automatic Succession.  The Escrow Agent may
resign at any time upon giving at least thirty (30) days written notice to
Microsemi and SymmetriCom; provided, however, that no such resignation shall
become effective until the appointment of a successor Escrow Agent which shall
be accomplished as provided below in this Section 10.  Upon any such
resignation, Microsemi and SymmetriCom shall use their best efforts to mutually
agree on a successor Escrow Agent within thirty (30) days after receiving such
notice.  If Microsemi and SymmetriCom fail to agree upon a successor Escrow
Agent within such time, Microsemi shall have the right to appoint a successor
escrow agent authorized to do business in the state of California.  The
successor Escrow Agent shall execute and deliver an instrument accepting such
appointment and all of the terms and conditions of this Escrow Agreement, and it
shall, without further acts, be vested with all the estates, properties, rights,
powers, and duties of the predecessor Escrow Agent as if originally named as
Escrow Agent.  The predecessor Escrow Agent shall be thereupon discharged from
any further duties and liability under this Escrow Agreement.  Any company into
which the Escrow Agent may be merged or with which it may be consolidated, or
any company to whom the Escrow Agent may transfer a substantial amount of its
Global Escrow business, shall be the successor to the Escrow Agent without the
execution or filing of any paper or any further act on the part of any of the
parties, anything herein to the contrary notwithstanding.

11.     Governing Law.  This Agreement shall be construed and enforced in
accordance with the laws of the State of California, it being understood and
agreed that disputes between the Purchaser Indemnified Persons and SymmetriCom
arising under the Merger Agreement shall be resolved under the governing law and
procedures set forth in such Agreement.

12.     Notice.  All notices and other communications required or permitted
