Item 1.01. Entry into a Material Definitive Agreement.

     The Registrant, Monolithic System Technology, Inc. ("MoSys" or the
"Company") and James R. Pekarsky entered into an employment offer letter
agreement, which was effective as of March 20, 2006. Pursuant to this agreement,
Mr. Pekarsky: (i) agreed to serve as Chief Financial Officer of the Company,
(ii) will receive an annualized base salary of $200,000, (iii) has been granted
an option (the "Option") to purchase 300,000 shares of the Company's common
stock as a new employee hiring inducement grant and not under the Company's
Amended and Restated 2000 Stock Option and Equity Incentive Plan. The Option has
a four-year vesting schedule, such that 25% of the total number of shares
subject to the Option will vest on the first anniversary of Mr. Pekarsky's
employment with the Company and 1/48 of the shares subject to the Option will
vest at the end of each successive calendar month thereafter, subject in all
events to Mr. Pekarsky's continued service with the Company.

     The Company and Mr. Pekarsky also entered into a Change-in-Control
Agreement, a Mutual Agreement to Arbitrate, an Indemnity Agreement and the
Company's standard form Employment Confidential Information and Invention
Assignment Agreement, all effective on March 20, 2006. The Change-in-Control
Agreement provides, amongst other things, that in the event of termination of
Mr. Pekarsky's employment by Mr. Pekarsky for Good Reason (as defined below)
within two years following a Change-in-Control (as defined below), Mr. Pekarsky
will be entitled to, amongst other things, the immediate and unconditional
vesting of 50 percent of the then unvested stock options and stock awards
previously granted to Mr. Pekarsky and, for the one-year period following
termination, the right to exercise any stock options or other awards held by
him. The Change-in-Control Agreement defines "Good Reason" as assignment to Mr.
Pekarsky of duties incompatible with his position, failure to maintain Mr.
Pekarsky in this position and its reporting relationship or a substantial
diminution in the nature of Mr. Pekarsky's authority or responsibilities;
reduction in Mr. Pekarsky's then current base salary or in the bonus or
incentive compensation opportunities or benefits coverage available during the
term of the Change-in-Control Agreement, except pursuant to an across-the-board
reduction similarly affecting all senior executives of MoSys; termination of Mr.
Pekarsky's employment, for any reason other than death, disability, voluntary
termination or misconduct; relocation of Mr. Pekarsky's principal place of
business to a location more than 30 miles from the location of such office on
the date of the Change-in-Control Agreement; MoSys's failure to pay Mr. Pekarsky
any material amounts otherwise vested and due to him under the Change-in-Control
Agreement or under any plan, program or policy of MoSys; or failure of a
successor to MoSys following a Change-in-Control to expressly assume or affirm
MoSys's obligations under the Change-in-Control Agreement. Under the
Change-in-Control Agreement, a "Change-in-Control" is defined as an acquisition
of 45% or more of the Company's outstanding voting securities by one individual
or entity or a group of stockholders or an acquisition of the Company which
results in the incumbent directors of Mosys immediately prior to the acquisition
not comprising at least a majority of the board of directors of the resulting
corporation, a new stockholder or group who did not previously own 45% or more
of the outstanding voting securities of the resulting corporation or other
entity becoming an owner of at least 45% of the outstanding voting securities of
such resulting corporation or other entity, or the Company's old stockholders
retaining less than 50% of the Company's outstanding voting securities.
