Item 2.   Acquisition or Disposition of Assets.

   On November 9, 1998, pursuant to that certain Merger Agreement dated as 
of October 21, 1998, between the Registrant, MISYN Acquisition Corp., a 
Delaware corporation and a wholly-owned subsidiary of the Registrant ("Merger 
Sub"), and Synergy Semiconductor Corporation, a California corporation 
("Synergy"), as amended by that certain side letter dated November 9, 1998, 
between the Registrant and Synergy (as so amended the "Merger Agreement"), 
the Registrant acquired Synergy through the merger of Merger Sub with and 
into Synergy for a cash purchase price of $9.9 million (the "Purchase 
Price").  Twenty percent (20%) of the Purchase Price was deposited in escrow 
pursuant to the terms of that certain Escrow Agreement dated November 9, 
1998, by and between the Registrant, John F. Stockton, as representative of 
the Synergy shareholders, and Bank of the West.  The balance of the Purchase 
Price was transferred to the paying agent to be paid to the former Synergy 
shareholders pursuant to the terms of the Merger Agreement. The Registrant has
also agreed to pay transaction fees and direct merger costs of approximately
$600 thousand.

   Synergy's assets include, among other things, Synergy's accounts 
receivable, inventory, fixed and tangible personal property (including, 
without limitation, all machinery, equipment, supplies, tools, tooling, 
furniture, fixtures, hardware, dies and spare parts), intangible personal 
property, contracts, books and records, and an interest as tenant of certain 
real property in Santa Clara, California.  Synergy's assets also included 
certain intellectual property used in its business.

   The Purchase Price paid at the closing was paid from the Registrant's 
own working capital funds.  The Purchase Price was determined through arms-
length negotiations between the Registrant and Synergy, which negotiations 
took into account Synergy's financial position, operating history, 
products, intellectual property and other factors relating to Synergy's 
business.  There are no material relationships between Synergy and the 
Registrant or any of its affiliates, any director or officer of the 
Registrant, or any associate of any such director or officer

                             CONVERSION OF STOCK

   2.1   Consideration; Conversion of Stock.  

         2.1.1   At the Effective Time, by virtue of the Merger, and without 
further action by any person or entity, all of the shares of Seller Stock (as 
hereinafter defined) issued and outstanding immediately prior to the 
Effective Time (other than Dissenting Shares (as hereinafter defined)) shall 
be converted into and become the right to receive) the Consideration (as 
hereinafter defined) in accordance with Section 0 below.  All shares of 
Seller Stock held by Seller as treasury stock shall be canceled and no 
payment shall be made with respect thereto.  All Dissenting Shares shall be 
handled in accordance with Section 0.  Each issued and outstanding share of 
capital stock of Micrel Subsidiary shall, at the Effective Time, be 
automatically converted into one share of Seller Common Stock (as hereinafter 
defined).  For the purposes hereof, the term "Seller Stock" shall mean all 
issued and outstanding shares of Seller's common stock ("Seller Common 
Stock") immediately prior to the Effective Time, and all issued and 
outstanding shares of Seller's preferred stock ("Seller Preferred Stock"), 
immediately prior to the Effective Time.  For the purposes of this Agreement, 

                                     2
<PAGE>


the term "Consideration" shall mean the aggregate sum of $13,000,000 (minus 
the Seller Transaction Costs (as hereinafter defined)), as adjusted pursuant 
to Sections 2.1.3 and 2.1.4 below.  For the purposes of this Agreement, the 
term "Seller Transaction Costs" shall mean (a) all fees and costs (including, 
without limitation, attorneys', accountants', investment bankers', and 
consultants' fees and costs) incurred by Seller in connection with the 
transactions contemplated hereby, and (b) one-half (1/2) of the HSR filing 
fee.  No later than three (3) business days prior to the Closing Date, Seller 
shall deliver to Micrel, for Micrel's reasonable approval, a statement 
detailing the Seller Transaction Costs.  Any Seller Transaction Costs not 
included on such statement shall be deemed Micrel's Damages (as hereinafter 
defined).

         2.1.2   The Consideration shall be allocated first among the 
holders of shares of the Series BB Preferred Stock of Seller (the "Seller 
Series BB Preferred") issued and outstanding immediately prior to the 
Effective Time, if any, (other than the holders of Dissenting Shares) by 
allocating to each of such holders that portion of the Consideration equal to 
the product of (a) the Series BB Original Issue Price (as defined in Seller's 
Restated Articles of Incorporation ("Seller's Articles"), multiplied by (b) 
the number of shares of Seller Series BB Preferred held by such holder.  The 
Consideration shall then be allocated among the holders of shares of the 
Series AA Preferred Stock of Seller (the "Seller Series AA Preferred") issued 
and outstanding immediately prior to the Effective Time, if any, (other than 
the holders of Dissenting Shares) by allocating to each of such holders that 
portion of the Consideration equal to the product of (i) the Series AA 
Original Issue Price (as defined in Seller's Articles), multiplied by (ii) 
the number of shares of Seller Series AA Preferred held by such holder.  
After the applicable portion of the Consideration has been allocated to the 
holders of the issued and outstanding shares of Seller Series BB Preferred 
and Seller Series AA Preferred, respectively, if any, (other than the holders 
of Dissenting Shares) then any remaining Consideration will be allocated 
among the holders of shares of Seller Common Stock and holders of shares of 
Seller Series BB Preferred issued and outstanding immediately prior to the 
Effective Time, if any, by allocating to each of such holders that portion of 
the Consideration equal to the product of (1) the portion of the 
Consideration remaining after application in accordance with the first two 
sentences of this Section 2.1.2, multiplied by (2) a fraction, the numerator 
of which shall be (A) the aggregate of (a) the number of shares of Seller 
Common Stock held by such holder and (b) the number of shares of Seller 
Common Stock into which the number of shares of Seller Series BB Preferred 
held by such holder, if any, are convertible immediately prior to the 
Effective Time pursuant to Seller's Articles, and (B) the denominator of 
which shall be the aggregate of (I) the number of shares of Seller Common 
Stock outstanding immediately prior to the Effective Time, and (II) the 
number of shares of Seller Common Stock into which the number of shares of 
Seller Series BB Preferred outstanding immediately prior to the Effective 
Time, if any, are convertible immediately prior to the Effective Time 
pursuant to Seller's Articles.  

         2.1.3   At the Closing, a reasonable estimate of the adjustment to 
the Consideration provided for in Section 0 below shall be made by Seller 
based upon a review of the Shareholder Equity (as hereinafter defined), as of 
a date as close as practicable to the Closing Date (the "Estimated 
Adjustment").  The Estimated Adjustment shall be used as the basis of 
calculating and paying the Consideration at the Closing until such time as 
the Final Adjustment (as hereinafter defined) is fully determined.

                                     3
<PAGE>


         2.1.4   (a) The Consideration shall be adjusted upward or downward 
on a dollar for dollar basis to reflect any difference between the 
Shareholder Equity as shown on the projected balance sheet for the Company as 
of September 27, 1998 (the "Projected Balance Sheet"), a copy of which is 
attached hereto as Schedule 2.1.4, and the Shareholder Equity as shown on the 
Closing Date Balance Sheet (as hereinafter defined).  The term "Closing Date 
Balance Sheet" shall mean the Closing Date balance sheet of the business of 
Seller (the "Business") as at the close of business on the Closing Date.  The 
Closing Date Balance Sheet shall be prepared by Seller and Seller 
Representative and Seller's accountants from the books and records of Seller 
in accordance with this Agreement and generally accepted accounting 
principles ("GAAP"), consistent with prior practice for Seller, subject to 
Section 2.1.4(b).  The Closing Date Balance Sheet shall be delivered to 
Micrel and its accountants no later than twenty (20) days after the Closing 
Date.  The Closing Date Balance Sheet shall be reviewed by Micrel and 
Micrel's accountants.  In furtherance of Micrel's and its accountants' review 
of the Closing Date Balance Sheet, (a) prior to the Closing, Seller shall, 
and shall cause its accountants to, reasonably cooperate with Micrel and its 
accountants (which cooperation shall include, without limitation, furnishing 
Micrel and its accountants with the books and records of Seller and all other 
documentation reasonably requested by Micrel or its accountants, including, 
without limitation, access to the working papers related to Seller prepared 
by Seller's accountants), and (b) from and after the Closing, Seller 
Representative shall cause Seller's accountants to reasonably cooperate with 
Micrel and its accountants (including, without limitation, by causing 
Seller's accountants to provide to Micrel and its accountants access to all 
working papers prepared by such accountants with respect to Seller).  After 
delivery by Seller, Micrel and its accountants shall have thirty (30) days in 
which to review the Closing Date Balance Sheet and to notify Seller 
Representative in writing of any specific detailed objections thereto.  If 
Micrel does not provide such notice within such period, the Closing Date 
Balance Sheet (and the Final Adjustment calculated pursuant thereto) shall be 
deemed approved by Micrel.  For purposes of this Section 2.1.4(a), the term 
"Shareholder Equity" shall mean the shareholder's equity reflected on the 
Projected Balance Sheet or the Closing Date Balance Sheet, as applicable.  
Provided that the same shall not affect the Final Adjustment or otherwise 
affect any amounts payable to Seller's shareholders hereunder, Micrel may 
make such adjustments to any inventory reserves established by Seller deemed 
desirable by Micrel.

                 (b) For purposes of the preparation of the Closing Date 
Balance Sheet, the parties agree as follows:  (i) all work in progress 
products ordered by Seller from SiMI, but not delivered, prior to the date 
hereof shall be accrued and reflected as inventory (together with a 
corresponding liability) on the Closing Date Balance Sheet, in the amount 
certified by Seller pursuant to Section 7.1.4 hereof; (ii) a liability shall 
be entered on the Closing Date Balance Sheet in the aggregate amount of the 
estimated cost to settle all amounts owed to SiMI by Seller for products 
delivered by such entity to Seller prior to the Closing Date; (iii) all 
inventory previously sold to Future Electronics by Seller as of the Closing 
(but not sold by Future Electronics to third party end user customers) shall 
be accounted for on the Closing Date Balance Sheet in the same manner as that 
of Seller's other United States distributors; (iv) all accounts payable of 
Seller as of the Closing Date shall be entered on the Closing Date Balance 
Sheet as current liabilities in their full stated amount; and (v) the Closing 
Date Balance Sheet shall include a liability for the projected attorneys' 
fees and costs reasonably required to settle or otherwise finally resolve the 

                                     4
<PAGE>


case of Clarke v. Synergy, currently pending in Santa Clara County Superior 
Court, case no.  H-198206-8. 

         2.1.5   If, after notice as to any objections to the Closing Date 
Balance Sheet is timely and properly given to Seller Representative by Micrel 
pursuant to Section 2.1.4(a), the parties are unable to resolve their 
disagreements within thirty (30) days following Seller Representative's 
receipt of such notice, the matter in dispute shall be resolved by 
arbitration as provided in Section 12.18 hereof.  Resolution of such dispute 
by agreement of the parties hereto or by arbitration shall be final, 
conclusive and binding on the parties.  The Purchase Price shall be adjusted 
based upon such final resolution (the "Final Adjustment").  If, pursuant to 
the Final Adjustment, the Purchase Price is increased, within ten (10) days 
after the date on which the Final Adjustment is determined, Micrel shall, 
subject to Section 2.2.3 of this Agreement and the Escrow Agreement, deliver 
to the Seller Representative on behalf of the holders of Seller Stock (as of 
immediately prior to the Effective Time) the remainder of the Consideration 
in the manner calculated and allocated pursuant to Section 2.1.2.  If, 
pursuant to the Final Adjustment, the Purchase Price is decreased, Micrel 
shall be entitled to immediately receive and retain that portion of the 
Escrowed Cash (as hereinafter defined), equal to the amount of such decrease.  

         2.1.6   Notwithstanding anything to the contrary set forth in this 
Agreement, the following shall be deemed Micrel's Damages and Micrel shall be 
entitled to retain the same from the Escrowed Cash as and when provided in 
this Section 2.1.6:  (a) the aggregate value (in the amount set forth on the 
Closing Date Balance Sheet), if any, of all inventory reflected on the 
Closing Date Balance Sheet pursuant to clause (i) of Section 2.1.4(b) above 
that is unsold to end-users as at the date that is 365 days after the Closing 
Date; (b) the aggregate amount (the "SiMI Settlement Amount"), if any, by 
which (i) the amount Seller is required to pay (through settlement or 
otherwise) to SiMI exceeds (ii) the amount of the liability set forth on the 
Closing Date Balance Sheet pursuant to Section 2.1.4(b)(ii); and (c) the 
amount, if any, by which the aggregate value of all end-user sales returns to 
Seller (that Seller is contractually obligated to take back) between the 
Closing Date and the date that is 180 days thereafter, exceeds the amount of 
any liability or reserve entered on the Closing Date Balance Sheet with 
respect thereto.  With respect to clause (b) above, if on the date that is 
180 days after the Closing Date, the SiMI Settlement Amount has not been 
determined (because the amounts owing to SiMI has not been settled (including 
due to the failure of Seller Representative to approve any settlement as 
provided below) or otherwise), Micrel and Seller Representative shall use 
their good faith efforts to agree on the SiMI Settlement Amount, provided 
that if such Persons cannot so agree within thirty (30) days after the 
expiration of such 180 day period, such period shall be extended to the date 
that is 365 days after the Closing Date.  If at the end of such 365 day 
period, the SiMI Settlement Amount has not been determined as provided above 
and Micrel and the Seller Representative have not agreed on the SiMI 
Settlement Amount, the SiMI Settlement Amount shall be determined by binding 
arbitration pursuant to Section 12.18 hereof.  With respect to any of the 
amounts set forth in clause (b) or (c) above, if and to the extent, at the 
date that is 180 days after the Closing Date (as such date may be extended 
pursuant to this Section 2.1.6 with respect to the determination of the SiMI 
Settlement Amount), the amount of the applicable liability set forth on the 
Closing Date Balance Sheet exceeds (x) the SiMI Settlement Amount, in the 
case of clause (b) above (as and when determined pursuant to this Section 
2.1.6), or (y) the aggregate value of all end-user sales returns (that Seller

                                     5
<PAGE>


is contractually obligated to take back) between the Closing Date and the 
date that is 180 days after the Closing Date, in the case of clause (c) 
above, the Consideration shall be increased by the amount of the net of any 
such excess (after taking into account any Micrel's Damages accrued prior to 
the date on which such excess is determined and not satisfied by application 
of the Escrowed Cash), and Micrel shall cause the same to be paid to the 
Seller Representative on behalf of the shareholders for distribution in the 
amounts and in the manner set forth in this Agreement.  Micrel shall use its 
reasonable commercial efforts, in the ordinary course of business, to (A) 
sell any and all inventory described in clause (a) above at commercially 
reasonable prices (and giving effect to Micrel's normal gross margin 
requirements), which inventory shall be sold on a first in first out basis 
(subject to any customer restrictions on acquiring such inventory), and (B) 
settle the amounts owed to SiMI, if any, pursuant to clauses (b) above, 
provided that any such settlement shall be subject to the approval of Seller 
Representative, which approval shall not be unreasonably withheld or delayed.  
Micrel shall keep Seller Representative promptly informed of all developments 
and discussions related to any such settlement.  

   2.2   Payment of Consideration.  

         2.2.1   Subject to Section 2.2.2, on the Closing Date Micrel shall 
issue and deliver to the holders of Seller Stock, the Consideration (other 
than the Escrowed Cash) allocated to such shareholders in accordance with 
Schedule 0 attached hereto.

         2.2.2   From and after the Closing, Micrel shall ensure that the
paying agent appointed by Micrel (the "Paying Agent") has, as and when needed, 
amounts sufficient in the aggregate to provide all funds necessary for the 
Paying Agent to make payments pursuant to Section 2.2.1 to holders of shares 
of Seller Stock.  After the Effective Time, there shall be no transfers on 
the stock transfer books of the Surviving Corporation of shares of capital 
stock of Seller which were outstanding immediately prior to the Effective 
Time.  Promptly, but in no event more than five (5) business days, after the 
Effective Time, the Surviving Corporation shall cause to be mailed to each 
person who was, at the Effective Time, a holder of record of shares of Seller 
Stock a form of letter of transmittal and instructions for use in effecting 
the surrender of the certificates which, immediately prior to the Effective 
Time, represented any of such shares of Seller Stock in exchange for payment 
therefor.  Upon surrender to the Paying Agent of such certificates, together 
with such letter of transmittal, duly executed and completed in accordance 
with the instructions thereto, the Surviving Corporation shall promptly cause 
to be paid to the persons entitled thereto a check in the amount equal to the 
portion of the Consideration payable to such persons less any required tax 
withholdings.  No interest will be paid or will accrue on the amount payable 
upon the surrender of any such certificate.  If payment is to be made to a 
person other than the registered holder of the certificate surrendered, it 
shall be a condition of such payment that the certificate so surrendered 
shall be properly endorsed or otherwise in proper form for transfer and that 
the person requesting such payment shall pay any transfer or other taxes 
required by reason of the payment to a person other than the registered 
holder of the certificate surrendered or establish to the satisfaction of the 
Surviving Corporation or the Paying Agent that such tax has been paid or is 
not applicable.  One hundred and eighty (180) days following the Effective 

                                     6

arbitration, mediation, proceeding or investigation, at law or in equity or 
otherwise in, for or by any court or other governmental body or any 
arbitration, mediation or similar forum (collectively, "Litigation").  Seller 
is not subject to any decree, judgment, order, law or regulation of any court 
or other governmental body which could have a material adverse effect on the

salary rates, bonuses paid during the last fiscal year, and accrued vacation 
and sick leave for all the employees of Seller; and (iii) all group insurance

to, employee organizations or groups, nor is Seller currently engaged in any 
labor negotiations except in minor grievances not involving any employee 
organization or group, nor, to the knowledge of Seller, is Seller the subject 
of any union organization.  There is no pending or, to Seller's knowledge, 
threatened labor dispute, strike or work stoppage affecting the Business.  

         3.21.2   Section 3.21.2 of the Seller Disclosure Schedule lists

binding or not, to which Seller contributes to or has any obligation to or 
liability for (collectively, the "Employee Plans").  Each Employee Plan 
provides that it may be amended or terminated at any time and, except for 
benefits protected under Section 411(d) of the Code, all benefits payable to 
current or terminated employees or any beneficiary may be amended or 
terminated by Seller at any time without liability.

Multiemployer Plan (within the meaning of ERISA) and neither Seller has ever

Section 4980B of the Code and Sections 601 through 608 of ERISA.

         3.21.5   Each Employee Plan which is an "employee benefit plan", as 
defined in Section 3(3) of ERISA, has complied, in all material respects, 
since its inception, with (a) its terms, and (b) with the requirements 
provided by any and all statutes, orders or governmental rules or regulations 
currently in effect and applicable to the Employee Plan, including but not 
limited to ERISA and the Code.  To Seller's knowledge, Seller is not subject 
to a risk of liability to any governmental entity, including, without 
limitation, excise taxes or civil penalties, as the result of the application 
of any provision of ERISA or the Code.  No investigations or audits by a 
governmental entity, or other actions, demands, proposals, negotiations or 
claims with respect to any Employee Plan have occurred, or are pending, or, 
to Seller's knowledge, are threatened or imminent, against any employer who 
is participating (or who has participated) in any Employee Plan or any 
fiduciary (as defined in Section 3(21) of ERISA) of the Employee Plan or 


                                    17
<PAGE>


which otherwise concern matters covered or that would be covered by the 
Employee Plans.  Neither Seller, nor any fiduciary with respect to any 
Employee Plan, has any knowledge of any facts that could give rise to any 
such action, demand, proposal, negotiation or claim.

         3.21.6   The Internal Revenue Service has determined that each 
Employee Plan intended to qualify under Section 401(a) of the Code so 
qualifies as of the end of the remedial amendment period, as set forth in the 
Code and each trust maintained pursuant thereto is exempt from taxation under 
Section 501 of the Code.  Nothing has occurred since the date of the Internal 
Revenue Service's favorable determination letter that could adversely affect 
the qualification of the Employee Plan and its related trust. 

         3.21.7   True, correct and complete copies of (i) all documents 
creating or evidencing any Employee Plan listed in Section 3.21.2 of the 
Seller Disclosure Schedule, (ii) all reports, forms and other documents 
required to be filed with any governmental entity (including, without 
limitation, summary plan descriptions, Forms 5500 and summary annual reports 
for all plans subject to ERISA), and (iii) the latest favorable letters of 
determination from the Internal Revenue Service with respect to the  Employee 
Plans that are intended to qualify under Section 401(a) of the Code have been 
delivered to Micrel.

         3.21.8   All expenses and liabilities relating to all of the 
Employee Plans described in Section 3.21.2 of the Seller Disclosure Schedule 
have been, and will on the Closing Date be, fully and properly accrued on 
Seller's books and records and are disclosed on the Current Balance Sheet and 
such Employee Plans have no unfunded liabilities not reflected on the Current 
Balance Sheet. 

         3.21.9   Without limiting any other representation or warranty of 
Seller set forth herein, the termination of the employment of any and all 
officers and employees of Seller prior to the date hereof was effected in 
accordance with all applicable laws and the employment arrangements between 
Seller and such officers and employees and Seller has no liability or 
obligation (including, without limitation, any liability for severance 
payments), absolute or contingent, to any former officer or employee of 
Seller.  No former officer or employee of Seller will, at the Closing, have 
any debt, liability or other obligation, absolute or contingent, owing to 
Seller.

Seller is not in material violation of any federal, state or local statutes, 
laws, regulations or rules relating to occupational health or safety, 
including, without limitation, the rules and regulations of the Occupational 
Safety and Health Administration ("OSHA").  No investigation or claim has at 
any time been commenced or pending against Seller or the Business or any real 
property owned or occupied at any time by Seller by OSHA or any similar state 
or local agency and, to Seller's knowledge, no basis exists for any such 
investigation or claim.  No claim has at any time been made by any current or 
former employee of Seller relating to occupational health or safety.

failure of computer hardware or software products or technology to calculate 
any information dependent on or relating to dates on or after January 1, 2000

shall directly or indirectly encourage, solicit, initiate or conduct 
discussions or negotiations with, provide any information to, or enter into 
any agreement with, any corporation, partnership, limited liability company,

waiting period under HSR.

   5.8   Notification of Certain Matters.  Without limiting Section 0, 
Seller shall give prompt notice to Micrel of the occurrence or non-occurrence 
of any event which causes or is likely to cause any representation or 
warranty made by Seller herein to be untrue or inaccurate or any covenant, 
condition or agreement contained herein not to be complied with or satisfied 
(provided, however, that any such disclosure shall not in any way be deemed

thereof).

contemplated hereby or delivered pursuant hereto, shall survive the Closing 


                                    28
<PAGE>


Date to until the date that is 180 days after the Closing Date.  The 
representations and warranties of Micrel Subsidiary and Micrel contained in 
this Agreement or in any document, certificate or instrument contemplated 
hereby or delivered pursuant hereto, shall survive the Closing Date to until 
the date that is 180 days after the Closing Date.

   8.2   Seller's Indemnity.  

         8.2.1   Seller shall indemnify, defend, protect and hold harmless 
Micrel (and Micrel's Subsidiaries and Affiliates and their respective 
officers, directors, shareholders, employees and agents) from and against any 
and all losses, costs, expenses, liabilities, obligations, claims, demands, 
causes of action, suits, settlements and judgments of every nature, including 
the costs and expenses associated therewith and reasonable attorneys', 
consultants' and witness fees incurred in connection therewith ("Micrel's 
Damages"), which arise out of: (i) the breach of any representation or 
warranty made by Seller under of this Agreement or any document or 
certificate delivered by Seller pursuant to this Agreement; (ii) the non-
performance, partial or total, of any covenant made by Seller pursuant to 
this Agreement or any document or certificate delivered by Seller pursuant to 
this Agreement; or (iii) any claim against Seller by Five Star Telecom, 
accruing from facts or circumstances first occurring prior to the date 
hereof.  "Micrel's Damages" shall also include any other matters deemed 
"Micrel's Damages" pursuant to this Agreement.

         8.2.2   Notwithstanding anything herein to the contrary, from and 
after the Closing Date, Seller shall protect, defend, indemnify and hold 
harmless Micrel from any and all taxes of Seller which are (i) imposed on 
Micrel that Micrel pays, otherwise satisfies in whole or in part, or result 
in liens or encumbrances on any assets of Micrel or (ii) imposed on Seller in 
respect of its income, business, property or operations or for which Seller 
may otherwise be liable, which are attributable to Seller's income, business, 
property operations on or before the Closing Date. 

         8.2.3   Notwithstanding anything to the contrary set forth in this 
Section 8.2, except as provided in the next sentence, no claim for Micrel's 
Damages shall be made unless and until the aggregate of all Micrel's Damages 
exceeds the sum of $130,000 (the "Indemnification Threshold"), provided that, 
if and when the aggregate of all Micrel's Damages equals or exceeds the 
Indemnification Threshold, Micrel shall be entitled to receive all Micrel's 
Damages, including all Micrel's Damages below the Indemnification Threshold.  
Notwithstanding the foregoing, no Micrel's Damages pursuant to Section 2.1.1 
or Section 2.1.6 of this Agreement shall be subject to the Indemnification 
Threshold.

         8.2.4   In the event the Merger is not consummated, Seller's 
aggregate liability for Micrel's Damages shall not exceed the Purchase Price.  
From and after the Effective Time, Seller's aggregate liability for Micrel's 
Damages shall not exceed the value of the Escrowed Cash and any increase in 
the Consideration payable by Micrel pursuant to the penultimate sentence of 
Section 2.1.6, and Micrel and Micrel Subsidiary's sole recourse in respect of 
a claim for indemnification under this Article 8 shall be to the Escrowed 


                                    29
<PAGE>


Cash and any such increase in accordance with the provisions of the Escrow 
Agreement and Section 2.1.6 hereof.  Notwithstanding the foregoing, nothing 
in this Section 8.2.3 shall limit the liability of Seller with respect to any 
Micrel's Damages due to the fraud or intentional misrepresentation of Seller.

         8.2.5   To secure the indemnification obligation of the Seller to 
Micrel and Micrel Subsidiary, the Escrowed Cash shall be deposited into 
escrow with the Escrow Agent in accordance with Section 2.24 hereof and the 
Escrow Agreement. 

   8.3   Micrel's Indemnity.  

         8.3.1   Micrel Subsidiary and Micrel shall, jointly and severally, 
indemnify, defend, protect and hold harmless Seller (and Seller's Affiliates 
and their respective officers, directors, shareholders, employees and agents) 
from and against any and all losses, costs, expenses, liabilities, 
obligations, claims, demands, causes of action, suits, settlements and 
judgments of every nature, including the costs and expenses associated 
therewith and reasonable attorneys', consultants' and witness fees incurred 
in connection therewith ("Seller's Damages"; and when used together with or 
in the alternative to Micrel's Damages, "Damages"), which arise out of:  the 
breach by Micrel Subsidiary or Micrel of any certification, representation or 
warranty made by Micrel Subsidiary or Micrel pursuant to this Agreement or 
any document or certificate delivered by Seller pursuant to this Agreement; 
or the non-performance, partial or total, of any covenant made by Micrel 
Subsidiary or Micrel pursuant to this Agreement required to be performed 
prior to the Closing or any document or certificate delivered by Seller 
pursuant to this Agreement.

         8.3.2   In the event the Merger is not consummated, Micrel's and 
Micrel Subsidiary's aggregate liability for Seller's Damages shall not exceed 
the Purchase Price.  From and after the Effective Time, Micrel's and Micrel 
Subsidiary's aggregate liability for Seller's Damages shall not exceed the 
value of the Escrowed Cash.  

   8.4   Indemnity Procedures.  

         8.4.1   In the event that at any time or from time to time after 
the Closing Date a person or entity entitled to indemnification pursuant to 
Section 0 or 8.3 (any such person or entity , an "Indemnitee") shall sustain 
a loss of any nature whatsoever against which such Indemnitee is indemnified 
under this Agreement, such Indemnitee shall notify the party required to 
provide such indemnification and, in the case of Seller, Seller 
Representative (such party and Seller Representative, as applicable, the 
"Indemnitor") in writing of any such loss so sustained, and Indemnitor shall 
within thirty (30) days after transmittal of such notice pay to such 
Indemnitee the amount of such loss so sustained, subject to their right to 
contest any third-party claim which has not yet resulted in a loss, as 
hereinafter provided in Section 0.

         8.4.2   Promptly after receipt by an Indemnitee of written notice 
of a claim or the commencement of any proceeding against it, such Indemnitee 
shall, if a claim in respect thereof is to be made against an Indemnitor 
under Section 0 or 0, give written notice to the Indemnitor of the 
commencement thereof, but the failure so to notify the Indemnitor shall not 
relieve it of any liability that it may have to any Indemnitee, except to the 
extent, the Indemnitor demonstrates that the defense of such action is or has


                                    30
<PAGE>


been prejudiced thereby.  In case any such proceeding shall be brought 
against an Indemnitee and it shall give notice to the Indemnitor of the 
commencement thereof, the Indemnitor shall be entitled to participate therein 
and, to the extent that it shall wish (unless the Indemnitor is also a party 
to such proceeding and the Indemnitee determines in good faith that joint 
representation would be inappropriate) to assume the defense thereof with 
counsel which is reasonably satisfactory to such Indemnitee and, after notice 
from the Indemnitor to such Indemnitee of its election so to assume the 
defense thereof, the Indemnitor shall not be liable to such Indemnitee under 
such Section for any fees of such counsel or any other expenses with respect 
to the defense of such proceeding, in each case, subsequently incurred by 
such Indemnitee in connection with the defense thereof.  If an Indemnitor 
assumes the defense of such proceeding, (a) no compromise or settlement 
thereof may be effected by the Indemnitor without the Indemnitee's reasonable 
consent unless (i) there is no finding or admission of any violation of law 
or any violation of the rights of any person or entity and no effect on any 
other claims that may be made against the Indemnitee, and (ii) the sole 
relief provided is monetary damages that are paid in full by the Indemnitor; 
and (b) the Indemnitor shall have no liability with respect to any compromise 
or settlement thereof effected without its consent (which shall not be 
unreasonably withheld).  If notice is given to an Indemnitor of the 
commencement of any proceeding and it does not, within fifteen (15) business 
days after the Indemnitee's notice is given, give notice to the Indemnitee of 
its election to assume the defense thereof, the Indemnitor shall be bound by 
any determination made in such action or any compromise or settlement thereof 
effected by the Indemnitee.  Notwithstanding the foregoing, if an Indemnitee 
determines in good faith that there is a reasonable probability that a 
proceeding may adversely affect it or its Affiliates, other than as a result 
of monetary damages, such Indemnitee may, by notice to the Indemnitor, assume 
the exclusive right to defend, compromise or settle such proceeding, but the 
Indemnitor shall not be bound by any determination of a proceeding so 
defended or any compromise or settlement thereof effected without its consent 
(which shall not be unreasonably withheld).

         8.4.3   If any Indemnitor contests or challenges any claim or 
action asserted against an Indemnitee referred to in this Article, it shall 
do so at its own cost and expense, holding Indemnitee harmless from all 
costs, fees, expenses, debts, liabilities and charges in connection with such 
contest; shall diligently defend against any such claim; and shall hold 
Indemnitee's business and assets free and harmless from any attachment, 
execution, judgment, lien or other legal process.

         8.4.4   Each Indemnitor further agrees to indemnify each Indemnitee 
for taxes imposed on or with respect to an indemnification payment made by 
such Indemnitee pursuant to this Article 8.

   8.5   Other Remedy.  If the Merger is consummated as contemplated 
herein, this Article 8 shall set forth the sole and exclusive remedy and 
recourse of the parties for any Damages resulting from, relating to or in 
connection with the Merger or the transactions contemplated hereby, except to 
the extent such Damages are due to or arise from the fraud or intentional 
misrepresentation of the applicable party.

   8.6   The Seller Representative. 

         8.6.1   The Seller, on behalf of each of its officers, directors 
and shareholders, hereby authorizes, directs and appoints John F. Stockton to 
act as sole and exclusive agent, attorney-in-fact and representative of its 
shareholders (the "Seller Representative"), and authorized and directs the 
Seller Representative to (i) take any and all actions (including without 
limitation executing and delivering any documents, incurring any costs and 
expenses for the account of the Seller (which will constitute Micrel's 
Damages incurred or suffered by Micrel and Micrel Subsidiary within the 
meaning of Section 8.2 hereof) and making any and all determinations) which 
may be required or permitted by this Agreement, or the Escrow Agreement to be 
taken by the Seller or the Seller Representative, (ii) exercise such other 
rights, power and authority as are authorized, delegated and granted to the 
Seller Representative hereunder and under the Escrow Agreement in connection 
with the transactions contemplated hereby and thereby and (iii) exercise such 
rights, power and authority as are incidental to the foregoing.  Any such 
actions taken, exercises of rights, power or authority, and any decision or 
determination made by the Seller Representative consistent therewith, shall 
be absolutely and irrevocably binding on Seller and its shareholders (the 
"Seller Indemnitors"), as if such party personally had taken such action, 
exercised such rights, power or authority or made such decision or 
determination in such party's individual capacity.  Notwithstanding any other 
provision of this Agreement, if the Closing occurs, then with respect to the 
matters covered by Article 8, (x) each of the Seller Indemnitors irrevocably 
relinquishes such Seller Indemnitors' right to act independently and other 
than through the Seller Representative, except with respect to the removal of 
the Seller Representative or appointment of a successor Seller Representative 
as provided in Section 8.6(b) below, and (y) no Seller Indemnitors shall have 
any right under this Agreement or otherwise to institute any suit, action or 
proceeding against the Company, Micrel and Micrel Subsidiary or the Escrow 
Agent with respect to any such matter, any such right being irrevocably and 
exclusively delegated to the Seller Representative.  The Seller 
Representative hereby acknowledges and accepts the foregoing authorization 
and appointment and agrees to serve as the Seller Representative in 
accordance with the Agreement and the Escrow Agreement. 

         8.6.2   The Seller Representative shall serve as Seller 
Representative until his resignation, removal from office, incapacity or 
death; provided, however, that the Seller Representative shall not have the 
right to resign without (A) prior written notice to the Seller Indemnitors 
and (B) picking a successor reasonably satisfactory to Micrel to serve until 
a successor thereto is elected by the Seller Indemnitors.  The Representative 
may be removed at any time and a successor representative, reasonably 
satisfactory to Micrel, may be appointed, pursuant to written action by 
Seller Indemnitors who, immediately prior to the Effective Time, held shares 
of Company Common Stock constituting 66 2/3% or more of all such shares then 
outstanding.  Any successor to the Seller Representative shall, for purposes 
of this Agreement, and the Escrow Agreement, be deemed to be, from the time 
of the appointment thereof if in accordance with the terms hereof, the Seller 
Representative, and from and after such time, the term "Seller 
Representative" as used herein and therein shall be deemed to refer to such 
successor.  No appointment of a successor shall be effective unless such 
successor agrees in writing to be bound by the terms of this Agreement and 
the Escrow Agreement. 


                                    32
<PAGE>


         8.6.3   Notwithstanding Section 8.4.3 hereof, the Seller 
Representative shall be permitted to retain counsel, consultants and other 
advisors and shall promptly notify Micrel and Micrel Subsidiary after 
retaining any such person.  All expense reimbursements paid to and received 
by the Seller Representative shall constitute Micrel's Damages incurred or 
suffered by Micrel within the meaning of Section 8.2 hereof. 

         8.6.4   The provisions of this Section 8.6 shall in no way impose 
any obligations on Seller (other than those set forth in Section 8.6.3 
above).  In particular, notwithstanding any notice received by Micrel and 
Micrel Subsidiary to the contrary (except any notice for the appointment of a 
successor Seller Representative approved by the Micrel and Micrel Subsidiary 
in accordance with Section 8.6.2) Micrel (i) shall be fully protected in 
relying upon and shall be entitled to rely upon, shall have no liability to 
the Seller Indemnitors with respect to, and shall be indemnified by the 
Seller Indemnitors from and against all liability arising out of (any such 
indemnifiable amounts constituting Micrel's Damages within the meaning of 
Section 8.2 hereof) actions, decisions and determinations of the Seller 
Representative and (ii) shall be entitled to assume that all actions, 
decisions and determinations of the Seller Representative are fully 
authorized by the Seller Indemnitors. 

         8.6.5   The Seller Representative shall not be liable to the Seller 
Indemnitors for the performance of any act or the failure to act so long as 
he acted or failed to act in good faith in what he reasonably believed to be

                             EMPLOYMENT MATTERS

   9.1   Employee Plans

         9.1.1   Micrel shall maintain the Employee Plans set forth in 
Section 3.21.1 of the Seller Disclosure Schedule for the purpose of providing 
continued coverage to each employee who was employed by Seller on the date 
hereof and was covered under such Employee Plans.  The continuation of such 
coverage will commence on the Closing Date and end on the date of such 
employee's termination of employment with Micrel or November 30, 1998, 
whichever is the first to occur.  

         9.1.2   Micrel shall terminate each of the Employee Plans effective 
December 31, 1998.  Alternatively, with respect to the Synergy Semiconductor 
Corporation 401(k) Plan (the "401(k) Plan") only, Micrel, in its sole 
discretion, may merge the 401(k) Plan with another qualified retirement plan 
maintained by Micrel as of December 31, 1998, rather than terminate said 
401(k) Plan.

         9.1.3   Effective January 1, 1999, Micrel will provide its current 
employees who were employed by Seller on the Closing Date with coverage under 
the Micrel group health plan under the same terms and conditions applicable 
to other Micrel employees on such date.  Micrel shall waive any preexisting 


                                    33
<PAGE>


conditions exclusions under said plan that would otherwise apply to employees 
who were employed by Seller on the date hereof.

         9.1.4   Effective January 1, 1999, Micrel will permit its current 
employees who were employed by Seller on the Closing Date hereof to commence 
participation in the Micrel 401(k) Plan under the same terms and conditions 
as apply to other Micrel employees on such date.  Micrel shall cause the 
401(k) Plan to credit such employees with all years of service while employed 
by Seller for all purposes under said plan, including vesting computation 
with respect to the future contributions made my Micrel to said plan on their 
behalf, if any.

                                  ARTICLE 10   
                  NONDISCLOSURE OF CONFIDENTIAL INFORMATION

   10.1   Nondisclosure.  Each party  recognizes and acknowledges that it 
has had in the past, currently have, and in the future may possibly have, 
access to certain Confidential Information (as defined below) related to the 
other parties to this Agreement.  Each party agrees that it will not disclose 
such Confidential Information to any person, firm, corporation, association 
or other entity for any purpose or reason whatsoever, except to their 
respective (a) to authorized representatives, and (b) to counsel and other 
advisers, provided that such advisers agree to the confidentiality provisions 
of this Section 0, unless (i) such information becomes available to or known 
by the public generally through no fault of the disclosing party, or 
(ii) disclosure is required by law or the order of any governmental authority 
under color of law, provided, that prior to disclosing any information 
pursuant to this clause (iii), the disclosing party shall, if possible, give 
prior written notice thereof to the affected party and provide the affected 
with the opportunity to contest such disclosure.  Nothing herein shall be 
construed as prohibiting the affected party from pursuing any other available 
remedy for such breach or threatened breach, including the recovery of 
damages.

   10.2   Confidential Information.  "Confidential information" shall mean 
all trade secrets and other confidential and/or proprietary information of 
the particular person or entity, including information derived from reports, 
investigations, research, work in progress, codes, marketing and sales 
programs, financial projections, cost summaries, pricing formulae, contract 
analyses, financial information, projections, confidential filings with any 
state or federal agency, and all other confidential concepts, methods of 
doing business, ideas, materials or information prepared or performed for, by 
or on behalf of such person by its employees, officers, directors, agents, 
representatives, or consultants.

   10.3   Nondisclosure Covenants: Remedy for Breach.  The parties agree 
that, in the event of breach or threatened breach of the covenants in this 
Article 10, the damage or imminent damage to the value and the goodwill of 
the non-breaching party will be irreparable and extremely difficult to 
estimate, making any remedy at law or in damages inadequate. Accordingly, the 
parties agree that the non-breaching party shall be entitled to injunctive 
relief against the breaching party, in the event of any breach or threatened 
breach of any of such covenants by the breaching party, in addition to any 
other relief (including damages) available to the non-breaching party under 
this Agreement or under law.

                                   TERMINATION

   11.1   Grounds for Termination.  This Agreement may be terminated at any 
time prior to the Closing:

         11.1.1   by mutual written agreement of Seller and Micrel; or

         11.1.2   by either Seller or Micrel if the Merger shall not have 
been consummated on or before December 31, 1998; or

         11.1.3   by Micrel in the event of the Seller's material breach of 
any of its covenants, representations or warranties under this Agreement; or

         11.1.4   by Seller in the event of Micrel's or Micrel Subsidiary's 
material breach of any of their respective covenants, representations or 
warranties under this Agreement.

   11.2   Effect of Termination.  If this Agreement is terminated as 
permitted by Section 0, such termination shall, except as set forth in the 
next sentence, the parties hereto shall have no further obligations to each 
other, provided that no such termination shall impair, limit or affect, in 
any manner, any liability of any party hereto for any breach of any covenant, 
representation or warranty set forth in this Agreement, accrued as of the 
date of such termination.  The provisions of Sections 0, 8.3, 8.4, 0, 0, 0, 
0, 0, and 0 shall survive any termination hereof pursuant to Section 0.  

                                   ARTICLE 12   
                                  MISCELLANEOUS

   12.1   Announcements.  Neither party shall announce or otherwise 
disclose the fact of or the terms and conditions of the transactions 
contemplated hereby except pursuant to a press release, to be issued upon the 
execution hereof, mutually agreed upon by Seller and Micrel.

   12.2   Finders and Brokers.  Except as provided in the next sentence, 
each party hereby represents and warrants to the others that neither it nor 
its representatives have taken, nor will they take, any action that would 
cause the other parties hereto to have any obligation or liability to any 
person for or made any arrangements for the payment of any finders' fees, 
brokerage fees, agents' commissions, or like payments in connection with the 
transactions contemplated hereby.  Micrel has engaged the assistance of 
BancBoston Roberston Stephens ("BBRS"), and Seller has engaged the services 
of Broadview International LLC ("Broadview"), in connection with the 
transactions described herein.  Micrel shall be solely responsible for any 
and all fees and commissions payable to BBRS, and Seller shall be solely 
responsible for any and all fees and commissions payable to Broadview (which 
fees and commissions shall be paid prior to the Closing Date or accrued on 
the Closing Date Balance Sheet).  Each party shall indemnify and hold 
harmless the others from any claim that is asserted by any person for a 


                                    35
<PAGE>


finder's fee or like payment with respect to this Agreement arising from any 
act, representation or promise of the indemnifying party or its 
representative.

   12.3   Amendment.  Subject to applicable law, this Agreement may only be 
amended or supplemented by written agreement of Seller, Micrel Subsidiary and 
Micrel.

   12.4   Waiver of Compliance.  Any failure of Seller, on the one hand, or 
Micrel, on the other, to comply with any provision of this Agreement may be 
expressly waived in writing by Micrel or Seller, respectively, but such 
waiver or failure to insist upon strict compliance with such provision shall 
not operate as a waiver of, or estoppel with respect to, any subsequent or 
other failure.  No failure to exercise and no delay in exercising any right, 
remedy, or power hereunder shall operate as a waiver thereof, nor shall any 
single or partial exercise of any right, remedy, or power hereunder preclude 
any other or further exercise thereof or the exercise of any other right, 
remedy, or power provided herein or by law or in equity.  The waiver by any 
party of the time for performance of any act or condition hereunder does not 
constitute a waiver of the act or condition itself.

   12.5   Expenses; Attorneys' Fee.  Each party shall pay all expenses 
incurred by it or on its behalf in connection with this Agreement or any 
transaction contemplated hereby.  Any transfer or similar tax in connection 
with the sale of the Assets to Micrel shall be paid by Seller.

   12.6   Survival of Representations and Warranties.  The respective 
representations and warranties of each party contained herein shall not be 
deemed waived or otherwise affected by any investigation made by or on behalf 
of the other party and such representations and warranties shall survive the 
Closing and the consummation of the Asset purchase contemplated hereby as 
provided in Article 8.  All statements contained in this Agreement or in any 
schedule, exhibit, certificate, list, or other document delivered pursuant 
hereto shall be deemed representations or warranties, as the case may be (as 
such terms are used in this Agreement), of the party making such statements.

   12.7   Notices.  All notices, demands, and other communications required 
or permitted hereunder shall be made in writing and shall be deemed to have 
been duly given if delivered by hand, against receipt, or mailed, postage 
prepaid, certified or registered mail, return receipt requested, and

         Agreement") by and among Micrel, Incorporated ("Micrel"), MISYN 
         Acquisition Corp. ("Micrel Subsidiary"), Synergy Semiconductor 
         Corporation ("Seller"), and John F. Stockton (the "Seller 
         Representative").  All capitalized terms used herein, but not 
         defined, shall have the meanings set forth in the Merger 
         Agreement.

Gentlemen:

   The Merger Agreement provides, among other things, that Seller will 
prepare a Closing Date Balance Sheet, which will be subject to the review and 
approval of Micrel and will result in a mutually agreed upon Final Adjustment 
to the Consideration payable in connection with the Merger.  Representatives 
of all the parties to the Merger Agreement have met to discuss factors 
impacting the Closing Date Balance Sheet and the Final Adjustment.  In the 
interests of resolving all differences between them and finally and 
conclusively settling upon the mutually accepted Closing Date Balance Sheet 
and Final Adjustment for all purposes contemplated by the Merger Agreement, 
and to avoid the time, expense and uncertainty associated with completing the 
process of resolving these matters in the manner established in the Merger 
Agreement, and to resolve certain other interpretive issues related to the 
Merger Agreement, the parties hereby agree as follows:

   1.   Notwithstanding anything to the contrary set forth in Sections 
2.1.3, 2.1.4 or 2.1.5 of the Merger Agreement: (a) the balance sheet of 
Seller, dated as of November 5, 1998 and attached hereto as Schedule 1 is 
hereby deemed to be the Closing Date Balance Sheet approved by all parties to 
the Merger Agreement; (b) the Final Adjustment is hereby deemed to be an 
amount equal to $2,500,000; (c) the Seller Transaction Costs are hereby 
agreed to be $600,000; and (d) as a result of the foregoing, the aggregate 
amount of the Consideration, after giving effect to the reduction 
contemplated for the Seller Transaction Costs and any adjustments 
contemplated pursuant to Sections 2.1.3, 2.1.4 and 2.1.5 of the Merger 
Agreement, is hereby agreed to be $9,900,000.

   2.   The Escrowed Cash to be deposited with the Escrow Agent pursuant to 
Section 2.2.3 of the Merger Agreement shall be $1,980,000, and the aggregate 
amount of the Consideration to be initially deposited with the Paying Agent 
for distribution to holders of Seller Stock pursuant to Section 2.2.2 of the 
Merger Agreement shall be $7,920,000.


<PAGE>


   3.   Notwithstanding anything to the contrary set forth in the Merger 
Agreement, in the event that the Seller Transaction Costs exceed $600,000, 
the amount of such excess shall be deemed to be Micrel Damages.

   4.   The Closing Date is hereby agreed to be November 9, 1998.

   5.   The term "Business" is used in the Merger Agreement shall mean the 
business and operations of Seller.

   Other than as specifically contemplated by this letter, the Merger 
Agreement remains in full force and effect in all respects without 
modification.  This letter agreement has been duly executed by the parties 
hereto as of the date first written above.

                                       Very truly yours,

owned subsidiary of Micrel ("Merger Sub"), and Synergy Semiconductor

Agreement, dated as of October 21, 1998 (the "Merger Agreement").  All 
capitalized terms used herein but not defined shall have the meanings 
ascribed to such terms in the Merger Agreement.

   B.   Pursuant to the Merger Agreement, Merger Sub will merge with and 
into Synergy with Synergy being the survivor.  As a result of the Merger, all 
outstanding shares of capital stock of Synergy will automatically be 
converted into the right to receive cash comprising the Consideration, upon 
the terms and conditions set forth in the Merger Agreement.

   C.   Pursuant to the terms of the Merger Agreement, Micrel is required 
to deposit the portion of the Consideration comprising the "Escrowed Cash" 
into an escrow (the "Escrow") with Escrow Agent to be applied against and to 
secure the payment to Micrel of any reduction in the Purchase Price due to 
the Final Adjustment and any and all Micrel's Damages.  

   D.   In furtherance of the transactions contemplated by the Merger 
Agreement, the parties hereto have agreed to enter into this Agreement to set 
forth the parties' understanding with respect to the Escrow and the deposit 
and distribution of the Escrowed Cash.

   NOW, THEREFORE, in consideration of the mutual agreements contained 
herein, the Synergy Representative, Micrel and Escrow Agent hereby agree as 
follows:

                                   AGREEMENT

   1.   Appointment and Agreement of Escrow Agent.  Micrel and the Synergy 
Representative hereby appoint Escrow Agent as escrow agent for the Escrow.

Agent under this Agreement.

   2.   Deposit of Escrowed Cash; Period of Escrow.  Micrel and the Synergy 
Representative agree and acknowledge that, in accordance with Section 2.2.3 
of the Merger Agreement, Micrel has deposited with the Escrow Agent the 
Escrowed Cash ($1,980,000) required to be deposited on the Closing Date, 
receipt of which is hereby acknowledged by Escrow Agent.  Should Micrel be 
required to deposit additional Escrowed Cash with the Escrow Agent as a

of such funds to Micrel and the Synergy Representative as soon as practicable 
following their deposit with the Escrow Agent.  The term of the Escrow shall

Cash is distributed in accordance with Section 3 below.

   3.   Distribution of Escrowed Cash.  Distribution of the Escrowed Cash 
shall be made as follows:

         (a)   Upon receipt by Escrow Agent of (i) a certificate signed by

written determination of the arbitrators pursuant to Section 12.18 of the 
Merger Agreement, in either case setting forth the amount of the reduction in

Micrel is entitled to receive such Micrel's Damages, reasonable detail 
supporting the claim, and the date that such certificate was delivered to the 
Escrow Agent and the Synergy Representative (the "Notice Date"), and provided 
that the Escrow Agent does not receive a certificate signed by the Synergy 
Representative (a copy of which shall be concurrently delivered to Micrel)

   5.   Provisions Concerning the Escrow Agent.  The following provisions 
will control the rights, duties, liabilities, privileges and immunities of 
the Escrow Agent:

         (a)   The Escrow Agent is not a party to, and is not bound by nor 
(except as specifically provided herein) charged with notice of, any 
agreement between any one or more parties hereto, out of which this escrow 
may arise.  The Escrow Agent does not assume any responsibility or liability


                                     3
<PAGE>


for any transactions between Micrel and the Synergy Representative other than 
this Escrow Agreement.

         (b)   The duties of the Escrow Agent hereunder are only such as are 
herein specifically provided, being purely ministerial in nature, and the 
Escrow Agent shall have no implied duties or obligations nor any 
responsibility in respect of any of the cash, property or items deposited 
with it other than to faithfully follow the instructions contained herein or 
given to it as provided herein.

         (c)   The Escrow Agent acts hereunder as a depository.  All 
deposits are warranted by the depositing party to be valid deposits.  The 
Escrow Agent is not responsible for or liable in any manner whatever for the 
sufficiency, correctness, genuiness and validity of any cash deposit, 
security, document, or other item, which is a part of the Escrowed Cash or 
for any claim or action by any person, firm, corporation or trustee 
concerning the right or power of any depositor to make any transfer or the 
validity of the transfer of any part of the Escrowed Cash to Escrow Agent or 
for the value, validity, collectibility or marketability of any investment of 
the Escrowed Cash.

         (d)   The Escrow Agent in acting hereunder may assume the 
genuineness of any written notice, request, waiver, consent, certificate, 
receipt, authorization, power of attorney, or other paper or document which 
the Escrow Agent in good faith believes to be genuine and what it purports to 
be.

         (e)   The Escrow Agent shall not be liable for consequential or 
special damages.  The Escrow Agent will not be liable for anything which it 
may do or refrain from doing in connection herewith, except to the extent 
held by a final unappealable judgment of a court of competent jurisdiction to 
be the direct result of its own gross negligence or willful misconduct.

         (f)   The Escrow Agent may consult with legal counsel (including 
in-house counsel) in the event of any dispute or question as to the 
construction of any of the provisions hereof or its duties hereunder, and it 
will incur no liability if it acts in good faith and in accordance with the 
reasonable opinion and instructions of such counsel as to such matters.  The 
Escrow Agent shall not be required to institute or defend any action 
(including interpleader) or lawsuit brought in connection with Escrowed Cash.  
In the event of its participation in any such legal proceeding, the Escrow 
Agent shall receive full indemnity and shall be compensated for its services 
and reimbursed for its expenses associated therewith.

         (g)   In the event of any disagreement between any of the parties 
to this Agreement, or between them or any of them and any other person or 
entity resulting in adverse claims or demands being made in connection with 
the subject of this Agreement, or in the event that the Escrow Agent, in good 
faith, is in doubt as to what action it should take hereunder, the Escrow 
Agent may refuse to take any action hereunder so long as such disagreement 
continues or such doubt exists, and in any such event, the Escrow Agent will 
not be or become liable in any way or to any person or entity for its failure 
or refusal to act, and the Escrow Agent will be entitled either to: (i) 
continue to refrain from acting until the rights of all parties have been 
determined by a final and unappealable order of the court of competent 


                                     4
<PAGE>


jurisdiction, or all differences have been adjusted and all doubt resolved by 
agreement among all the interested persons or entities, and the Escrow Agent 
has been notified thereof in writing signed by all such persons or entities, 
or (ii) file an interpleader action in any court of competent jurisdiction, 
in which event all costs and expenses will be borne by Micrel and the Synergy 
Representative.

         (h)   The Escrow Agent may resign at any time upon thirty (30) days 
written notice to Micrel and the Synergy Representative.  In the event of 
such notice of resignation, prior to the expiration of such notice, Micrel 
and the Synergy Representative shall designate a successor escrow agent.  
Such successor escrow agent shall have accepted such designation and will 
serve as escrow agent on the same terms and conditions as set forth herein or 
on such other terms and conditions as are agreeable to Micrel and the Synergy 
Representative.  Upon written notice to the Escrow Agent of such designation, 
the Escrow Agent shall deliver all relevant funds deposited hereunder to the 
successor escrow agent, whereupon all the Escrow Agent's duties and 
obligations hereunder shall cease and terminate.

         (i)   Upon termination of this Agreement or the resignation of the 
Escrow Agent, the Escrow Agent may request, and Micrel and the Synergy 
Representative shall deliver to the Escrow Agent, a release satisfactory to 
the Escrow Agent releasing the Escrow Agent from all liability under this 
Agreement.

         (j)   The Escrow Agent's fees for its services hereunder shall be 
as set forth on Exhibit A hereto.  In addition to such fees, the Escrow agent 
shall be reimbursed for the reasonable fees and expenses of its legal counsel 
and other reasonable out-of-pocket expenses reasonably incurred by it for so 
long as any portion of the Escrowed Cash is held by the Escrow Agent 
hereunder.  All such fees shall be borne by Micrel and the Synergy 
Representative.  Payment for the first twelve (12) months of service shall be 
paid to the Escrow Agent upon the establishment of the Escrow by check in the 
amount of $5,500.  In addition, Micrel and Synergy Representative shall pay 
$5,000 to the Escrow Agent to be held as a cash reserve for future fees 
("Cash Reserve").  After the initial twelve (12) months of service, the 
Escrow Agent shall deduct its monthly fees from the Cash Reserve.  In the 
event the Cash Reserve is exhausted, service shall be billed on a month to 
month basis by the Escrow Agent to Micrel and the Synergy Representative, and 
shall be paid by Micrel and Synergy Representative upon receipt of such 
monthly bill.  Escrow Agent shall have a lien or right of set-off on all fund 
and property held hereunder to secure its rights hereunder to be indemnified 
and held harmless and to be reimbursed for all of its expenses arising out of 
or in connection with this Escrow Agreement.

   6.   Payment of Escrow Agent's Fees and Taxes.  Micrel will pay one-half 
and the Synergy Representative will pay one-half of all of the Escrow Agent's 
fees for services rendered by the Escrow Agent pursuant to the provisions of 
this Agreement and each will reimburse the Escrow Agent for one-half of its 
reasonable expenses incurred in connection with the performance by it of such 
services.  The Synergy Representative shall be responsible for any taxes 
owing in respect to the earnings on the Escrowed Cash and each of the Synergy 
Representative and Micrel shall provide the Escrow Agent with executed W-9 
forms.

   7.   Indemnification of Escrow Agent.  In consideration of its 
acceptance of the appointment as escrow agent, Micrel and Synergy 
Representative agree to indemnify the Escrow Agent against and hold the 
Escrow Agent harmless from all claims, liabilities, losses, actions, suits 
and proceedings incurred by it or to which it is made a party by reason of 
its having accepted the same or in carrying out any of the terms hereof, or 
otherwise relating to this agreement and to indemnify the Escrow Agent 
against and reimburse the Escrow Agent for all its expenses, including among 
other things, counsel feels and court costs, incurred by reason of its 
position hereunder or actions taken or omitted in good faith pursuant hereto 
unless such loss, liability or expense shall be caused by the Escrow Agent's 
gross negligence.  Micrel and Synergy Representative agree that the Escrow 
Agent shall not be liable to either of them for any actions taken by the 
Escrow Agent pursuant to the terms hereof.  In no event shall the Escrow 
Agent be liable for any incidental, special or consequential damages.

   8.   Merger Agreement Not Limited by this Agreement.  This Agreement and 
the deposit of the Escrowed Cash hereunder are without prejudice to, and are
