                             COMMON STOCK & WARRANTS

Alfacell Corporation
225 Belleville Avenue
Bloomfield, New Jersey 07003

Attention: Kuslima Shogen, Chairman
           and Chief Executive Officer

Dear Ms. Shogen:

     The undersigned  acknowledges that there is no minimum proceeds requirement
for  the  closing  of  this  Offering,   the  Company  may  close  only  on  the
undersigned's  investment  and such  investment  may be  inadequate  to meet the
Company's cash requirements. The Company intends to utilize the proceeds of this
Offering for research and development and general corporate purposes.

     The undersigned  hereby  subscribes to purchase  200,000 units at $0.50 per
unit (the "Unit").  Each Unit  consists of one share of Common Stock,  $.001 par
value per share (the "Shares") of Alfacell  Corporation,  a Delaware corporation
(the  "Company") and one five-year  warrant (the  "Warrants").  The Warrants are
exercisable into one Share (the "Warrant Shares").  The Shares, the Warrants and
the Warrant  Shares are being sold in a  transaction  exempt  from  registration
under the Securities  Act of 1933, as amended (the "Act").  The Warrants will be
issued pursuant to a Warrant  Agreement in the form attached hereto as Exhibit A
executed by the Company for the benefit of the undersigned. The Warrants will be
exercisable at $1.50 for a five-year  period  commencing  three months after its
issuance.  The  undersigned  tenders  herewith  $100,000 in full  payment of the
purchase price for the 200,000 Units to which the undersigned subscribes (in the
manner indicated on the signature page hereof.)

     The undersigned  understands  that the right to transfer all or any part of
the  Shares,  the  Warrants  and  the  Warrant  Shares  (hereinafter   sometimes
collectively   referred  to  as  the  "Securities")  will  be  restricted.   The
undersigned may not transfer the Securities unless they are registered under the
Act and  applicable  state  securities or "blue sky" laws, or an exemption  from
such  registration  is available.  The  undersigned  recognizes that the Company
shall have no obligation to register the Securities, except as set forth herein.

The undersigned hereby represents, warrants and covenant that:

     1. The  undersigned  is acquiring the Shares and the Warrants,  and at such
time as the undersigned may exercise the Warrants,  the Warrant Shares,  for the
undersigned's   own  account  for   investment  and  not  with  a  view  towards
distribution. The undersigned will not sell, hypothecate,  transfer or otherwise
dispose of the Securities  unless such transaction has been registered under the
Act  or,  in  the  opinion  of  counsel  for  the  Company,  an  exemption  from
registration is available.

     3.  Whether  or  not  the  representation  contained  in  paragraph  2(i)is

for  liquidity  of the  Securities.  The  undersigned's  overall  commitment  to

behalf of the Company in connection with the  acquisition of the Securities,  in
each case except as provided herein or in the Disclosure Documents.

     6. The undersigned  understands and  specifically  acknowledges  and agrees
that  since  the  Securities  have  not  been  registered  under  the  Act,  the
certificates representing the Securities will bear a legend to such effect and a
stop transfer order will be placed on the  Securities in the Company's  transfer
books.

     7. By its  acceptance  hereof,  the Company hereby agrees that it shall use
its best efforts to file a registration statement (the "Registration Statement")
under the Act to register the resale of the Shares and the

                                    2 of 13
<PAGE>

Warrant Shares. The Company further agrees to use its best efforts to cause such
Registration Statement to become effective.

     In  connection  with the  Registration  Statement,  the  undersigned  shall
provide the Company,  from time to time, as reasonably requested by the Company,
written information concerning its ownership of the Company's Securities,  their
intentions  concerning  the sale of its Shares and Warrant Shares and such other
matters as are  required  in order to enable the  Company to  prepare,  file and
obtain the effectiveness of such Registration Statement.  Notwithstanding any of
the foregoing,  the Company shall not be required to maintain the  effectiveness
of the  Registration  Statement  for more than two (2) years  after the  initial
effective date thereof.

     In connection with any such registration of Shares and Warrant Shares,  the
Company shall supply a reasonable number of prospectuses to the undersigned, use
its best  efforts to qualify the Shares and  Warrants  for sale in the states of
New York and New  Jersey  and  furnish  indemnification  in the manner set forth
below.

     The Company shall bear the entire cost and expense of any such registration
hereunder. Notwithstanding the foregoing, the undersigned shall bear the fees of
all persons  retained by it, such as counsel and  accountants,  and any transfer
taxes or  underwriting  discounts or  commissions  applicable  to the Shares and
Warrant Shares sold by it pursuant to the Registration Statement.

     The Company  shall  indemnify  and hold  harmless each holder of Shares and
Warrant Shares that are registered  pursuant to the  Registration  Statement and
each  underwriter,  within the meaning of the Act, who may purchase from or sell
for any such holder any such Shares or Warrant  Shares and each person,  if any,
who controls any such holder or underwriter  within the meaning of the Act, from
and against any and all losses,  claims,  damages and liabilities  caused by any
untrue statement of a material fact contained in the  Registration  Statement or
any post-effective amendment thereto or any prospectus included therein required
to be filed or  furnished in  connection  therewith or caused by any omission to
state therein a material fact required to be stated therein in order to make the
statements  made therein,  in light of the  circumstances  under which they were
made,  not  misleading,  except  insofar  as such  losses,  claims,  damages  or
liabilities  are caused by any such  untrue  statement  or  omission  based upon
information  furnished  or required to be furnished in writing to the Company by
such holder or underwriter  expressly for use therein;  provided,  however, that
such holder or underwriter  shall  indemnify the Company,  its  directors,  each
officer signing the Registration Statement and each person, if any, who controls
the Company  within the meaning of the Act, from and against any and all losses,
claims,  damages and  liabilities  caused by any untrue  statement of a material
fact contained in any  Registration  Statement or any  post-effective  amendment
thereto or any  prospectus  included  therein  required to be filed or furnished
pursuant  thereto or caused by any  omission  to state  therein a material  fact
required to be stated therein in order to make the statements  made therein,  in
light of the circumstances  under which they were made, not misleading,  insofar
as such  losses,  claims,  damages  or  liabilities  are  caused  by any  untrue
statement or omission based upon information furnished in writing to the Company
by any such holder or underwriter expressly for use therein.

                                    3 of 13
<PAGE>

     If the  indemnification  provided  for herein from either the holder of the
Shares and Warrant Shares or the Company is unavailable to an indemnified  party
(the  "Indemnitee")  hereunder  in respect  of any  losses,  claims,  damages or
liabilities (or actions in respect thereof)  referred to herein,  then the party
responsible for such indemnification (the "Indemnitor"), in lieu of indemnifying
the Indemnitee, shall contribute to the amount paid or payable by the Indemnitee
as a result of such losses, claims, damages or liabilities in such proportion as
is appropriate to reflect the relative fault of the Indemnitor and Indemnitee in
connection  with the actions which resulted in such losses,  claims,  damages or
liabilities  (including legal or other fees and expenses  reasonably incurred in
connection with any  investigation or proceeding) as well as any other equitable
considerations.

     If  indemnification  is available,  the  Indemnitor  shall  indemnify  each
Indemnitee to the full extent provided for herein without regard to the relative
fault of the  Indemnitor,  the Indemnitee or any other  equitable  consideration
provided for hereunder.

     After the Registration  Statement  becomes effective and in connection with
the sale of the Shares and Warrant Shares under such Registration Statement, the
undersigned  shall take such steps as may be  necessary to ensure that the offer
and  sale  thereof  are in  compliance  with  the  requirements  of the  federal
securities   laws,   including,   but  not  limited  to,   compliance  with  the
anti-manipulation  requirements  of the  Securities  Exchange  Act of  1934,  as
amended.

WARRANT AND SUCH SHARES MAY NOT BE SOLD, TRANSFERRED,  PLEDGED,  HYPOTHECATED OR
OTHERWISE  DISPOSED  OF, IN WHOLE OR IN PART,  IN THE  ABSENCE  OF AN  EFFECTIVE
REGISTRATION  STATEMENT UNDER THE ACT AND APPLICABLE STATE LAW, OR AN OPINION OF

NO.                                                                       SHARES

                              ALFACELL CORPORATION

     This certifies that, for value received,  ___________________________,  the
registered  holder  hereof or  assigns  (the  "Warrantholder")  is  entitled  to
purchase from Alfacell Corporation,  a Delaware corporation (the "Company"),  at
any time on and after  ___________________,  and before  5:00  p.m.,  New Jersey
time, on  _______________  (the  "Termination  Date"),  at the purchase price of
$1.50 per share (the  "Exercise  Price"),  the number of shares of Common Stock,
par value $.001 per share, of the Company set forth above (the "Warrant Stock").
The number of shares of Warrant  Stock,  the  Termination  Date and the Exercise
Price per share of this Warrant shall be subject to adjustment from time to time
as set forth below.

SECTION I. TRANSFER OR EXCHANGE OF WARRANT.

     The Company  shall be entitled to treat the  Warrantholder  as the owner in
fact hereof for all purposes and shall not be bound to recognize  any  equitable
or other claim to or interest in this  Warrant on the part of any other  person.
This Warrant shall be transferable only on the books of the Company,  maintained
at its principal office upon delivery of this Warrant  Certificate duly endorsed
by the Warrantholder or by his duly authorized  attorney or  representative,  or
accompanied  by proper  evidence  of  succession,  assignment  or  authority  to
transfer.  Upon any  registration  of transfer,  the Company shall deliver a new
Warrant Certificate or Certificates to the persons entitled thereto.

SECTION II. TERM OF WARRANT; EXERCISE OF WARRANTS.

     A.   Termination.  The  Company  may,  in its sole  discretion,  extend the
Termination Date with respect to the exercise of this Warrant upon notice to the
Warrantholder. As used herein, "Termination Date" shall be deemed to include any
such extensions.

     B.   Exercise. This Warrant shall be exercised by surrender to the Company,
at its principal office, of this Warrant Certificate, together with the Purchase
Form attached hereto duly completed and signed,  and upon payment to the Company
of the  Exercise  Price for the number of shares of Warrant

                                    6 of 13
<PAGE>

Stock in  respect  of which  this  Warrant  is then  exercised.  Payment  of the
aggregate  Exercise Price shall be made in cash or by certified or official bank
check.

     C.   Warrant  Certificate.   Subject  to  Section  III  hereof,  upon  such
surrender  of this  Warrant  Certificate  and payment of the  Exercise  Price as
aforesaid,  the  Company  shall issue and cause to be  delivered  to or upon the
written order of the  Warrantholder a certificate or certificates for the number
of full shares of Warrant Stock so purchased  upon the exercise of such Warrant,
together  with  cash,  as  provided  in  Section  VI  hereof,  in respect of any
fractional shares of Warrant Stock otherwise issuable upon such surrender.  Such
certificate or  certificates  representing  the Warrant Stock shall be deemed to
have been  issued  and any person so  designated  to be named  therein  shall be
deemed to have become a holder of record of such  shares of Warrant  Stock as of
the date of receipt by the Company of this  Warrant  Certificate  and payment of
the Exercise  Price as  aforesaid;  provided,  however,  that if, at the date of
surrender of this Warrant  Certificate  and payment of the Exercise  Price,  the
transfer  books for the Warrant Stock or other class of stock  purchasable  upon
the exercise of this Warrant shall be closed,  the  certificate or  certificates
for the  shares of  Warrant  Stock in  respect  of which  this  Warrant  is then
exercised shall be deemed issuable as of the date on which such books shall next
be opened (whether before or after the Termination Date) and until such date the
Company  shall be under no duty to deliver  any  certificate  for such shares of
Warrant Stock;  provided  further,  however,  that the transfer books of record,
unless  otherwise  required  by law,  shall  not be closed at any one time for a
period longer than twenty (20) days. The rights of purchase  represented by this
Warrant shall be exercisable,  at the election of the  Warrantholder,  either in
full or from time to time in part,  and,  in the  event  that  this  Warrant  is
exercised  in  respect  of  fewer  than  all  of the  shares  of  Warrant  Stock
purchasable  on such exercise at any time prior to the  Termination  Date, a new
Warrant Certificate evidencing the remaining Warrant or Warrants will be issued,
and the  Company  shall  deliver  the new Warrant  Certificate  or  Certificates
pursuant to the provisions of this Section.

SECTION III. PAYMENT OF TAXES.

     The Company will pay all documentary  stamp taxes, if any,  attributable to
the initial  issuance of the shares of Warrant  Stock upon the  exercise of this
Warrant;  provided,  however,  that the Warrantholder shall pay any tax or taxes
which  may be  payable  in  respect  of any  transfer  involved  in the issue or
delivery of Warrant  Certificates or the  certificates for the shares of Warrant
Stock in a name  other than that of the  Warrantholder  in respect of which this
Warrant or shares of Warrant Stock are issued.

SECTION IV. MUTILATED OR MISSING WARRANT CERTIFICATES.

     In case  this  Warrant  Certificate  shall be  mutilated,  lost,  stolen or
destroyed,  the Company shall,  at the request of the  Warrantholder,  issue and
deliver,  in  exchange  and  substitution  for  and  upon  cancellation  of this
certificate if mutilated, or in lieu of and in substitution for this certificate
if lost,  stolen or  destroyed,  a new  Warrant  Certificate  of like  tenor and
representing an equivalent right or interest,  but only upon receipt of evidence
satisfactory  to the Company of such loss,  theft or destruction of this Warrant
Certificate and indemnity, if requested, also satisfactory to the Company.

                                    7 of 13
<PAGE>

SECTION V. RESERVATION OF SHARES OF WARRANT STOCK.

     There has been  reserved,  and the Company shall at all times keep reserved
so long as this Warrant remains outstanding,  out of its authorized Common Stock
a number of shares of Common Stock sufficient to provide for the exercise of the
rights of purchase  represented  by this  Warrant.  The  transfer  agent for the
Common Stock and every subsequent transfer agent for any shares of the Company's
capital  stock  issuable  upon the exercise of this Warrant will be  irrevocably
authorized and directed at all times to reserve such number of authorized shares
as shall be requisite for such purpose.

SECTION VI. FRACTIONAL SHARES.

     No  fractional  shares or scrip  representing  fractional  shares  shall be
issued upon the  exercise of this  Warrant.  With  respect to any  fraction of a
share called for upon the exercise of this Warrant, the Company shall pay to the
Warrantholder an amount in cash equal to such fraction multiplied by the current
market price of such fractional share. "Market Price", as of any date means, (i)
the last  reported  sale price for the shares of Common Stock as reported by the
National  Association of Securities Dealers Automated  Quotation National Market
System,  ("NASDAQ-NMS"),  (ii) the  closing  bid price for the  shares of Common
Stock as reported by the National  Association of Securities  Dealers  Automated
Quotation  System  ("NASDAQ") if the shares are not traded on NASDAQ-NMS,  (iii)
the average of the closing bid and closing  asked  prices of the Common Stock as
reported  by the  National  Quotations  Bureau if the  shares  are not traded on
NASDAQ;  (iv) the last  reported  sale price,  if the shares of Common Stock are
listed  on a  national  securities  exchange  or (v) if market  value  cannot be
calculated as of such date on any of the foregoing  basis, the fair market price
determined  by the Board of  Directors of the  Company,  acting with  reasonable
business judgment.

SECTION VII. EXERCISE PRICE; ANTI-DILUTION PROVISIONS.

     A.   Exercise Price.  The shares of Warrant Stock shall be purchasable upon
the exercise of this Warrant, at a price of $1.50 per share. The Company may, in
its sole  discretion,  reduce the Exercise  Price  applicable to the exercise of
this Warrant upon notice to the Warrantholder.  As used herein, "Exercise Price"
shall be deemed to include any such reduction.

     If the Company  shall at any time issue  Common Stock by way of dividend or
other  distribution  on any  stock of the  Company  or  effect a stock  split or
reverse  stock split of the  outstanding  shares of Common  Stock,  the Exercise
Price shall be  proportionately  decreased in the case of such  issuance (on the
day following the date fixed for  determining  stockholders  entitled to receive
such  dividend or other  distribution  or such stock  split) or increased in the
case of such  reverse  stock  split (on the date that such  reverse  stock split
shall become effective), by multiplying the Exercise Price in effect immediately
prior to the stock dividend or other distribution,  stock split or reverse stock
split by a fraction,  the  numerator  of which is the number of shares of Common
Stock   outstanding   immediately   prior  to  such  stock   dividend  or  other
distribution,  stock split or reverse stock split,  and the denominator of which
is the number of shares of Common Stock outstanding immediately after such stock
dividend or other distribution, stock split or reverse stock split.

                                    8 of 13
<PAGE>

     B.   No Impairment.  The Company (a) will not increase the par value of any
shares of stock  receivable  upon the exercise of this Warrant  above the amount
payable therefor upon such exercise, and (b) will take all such action as may be
necessary or appropriate in order that the Company may validly and legally issue
fully paid and  nonassessable  shares of Common  Stock upon the exercise of this
Warrant.

     C.   Number of Shares  Adjusted.  Upon any adjustment of the Exercise Price
pursuant to this Warrant, the Warrantholder shall thereafter (until another such
adjustment)  be entitled to purchase upon the exercise of this  Warrant,  at the
new Exercise Price, the number of shares,  calculated to the nearest full share,
obtained by multiplying the number of shares of Warrant Stock initially issuable
upon exercise of this Warrant by the Exercise Price in effect on the date hereof
and dividing the product so obtained by the new Exercise Price.

SECTION VIII. RECLASSIFICATION, REORGANIZATION OR MERGER.

     In case of any reclassification,  capital reorganization or other change of
outstanding  shares of Common  Stock of the Company  (other than a change in par
value or as a result of an issuance of Common  Stock by way of dividend or other
distribution  or of a stock  split or  reverse  stock  split)  or in case of any
consolidation or merger of the Company with or into another  corporation  (other
than a merger with a subsidiary  in which  merger the Company is the  continuing
corporation  and  which  does  not  result  in  any  reclassification,   capital
reorganization  or other  change of  outstanding  shares of Common  Stock of the
Company  issuable  upon  exercise  of this  Warrant)  or in case of any  sale or
conveyance to another  corporation of the property of the Company as an entirety
or substantially as an entirety,  the Company shall cause effective provision to
be made so that the Warrantholder shall have the right thereafter, by exercising
this  Warrant,  to  purchase  the kind and  amount  of shares of stock and other
securities and property the Warrantholder would have been entitled to receive if

                              SEPARATION AGREEMENT
                           GENERAL RELEASE AND WAIVER

                  SEPARATION AGREEMENT and GENERAL RELEASE and WAIVER (this
"Agreement") made as of December 3, 2001 (the "Execution Date"), by and among
Gerald Chien Kuo Hsu (the "Employee"), Synopsys, Inc. ("Synopsys"), and Avant!
Corporation, (the "Employer," together with Synopsys and the Employee, the
"Parties").

                  WHEREAS, the Employer engaged the Employee to be an employee
of the Employer;

                  WHEREAS, the Employee and the Employer are parties to an
Employment Agreement, dated August 24, 2000 (the "August 24, 2000 Agreement"),
and a Modification Agreement, dated July 25, 2001, (together with the August 24,
2000 Agreement, the "Employment Agreement"); and

                  WHEREAS, the Parties wish to confirm the termination of the
Employee's employment with the Employer and set forth their agreement as to the
manner in which the Employee's employment with the Employer will be closed out.

                  NOW, THEREFORE, in consideration of the mutual covenants set
forth herein and for other good and valuable consideration, receipt of which is
hereby acknowledged, the Parties agree as follows:

                  1. Confirmation of Termination. The Parties hereby now
acknowledge and confirm that the Employee's employment with the Employer and its
affiliates (as defined in Rule 12b-2 under the Securities Exchange Act of 1934,
as amended (the "Affiliates" and the "Exchange Act") shall terminate as of the
Effective Time (as defined in the Agreement and Plan of Merger by and among
Synopsys, Maple Forest Acquisition LLC and the Employer, dated as of December 3,
2001 (the "Merger Agreement")) (the "Termination Date"). The Employee hereby
resigns, effective as of the Termination Date, all positions, titles, duties,
authorities and responsibilities with, arising out of or relating to his
employment with the Employer or its Affiliates, including all positions on the
board of directors (or any committee thereof) of the Employer or its Affiliates.
The Parties acknowledge and agree that neither Party shall be required to
perform any of its obligations under this Agreement, and the releases contained
in Section 3 of this Agreement shall not become effective, until the Effective
Time under the Merger Agreement shall have occurred, and that this Agreement
shall terminate automatically, and neither Party shall have any liability
hereunder, if the Merger Agreement shall have been terminated as provided
therein. Notwithstanding the preceding sentence, the Employee agrees that he
shall not, at any time between the Execution Date and either the Effective Time
or a termination of the Merger Agreement, exercise any of his rights to
terminate the Employment Agreement under Section 8(a)(i) or 8(c) of the August
24, 2000 Agreement; provided, however, that if during such time period any
ground shall arise on which the Employee would otherwise be entitled to
terminate the Employment Agreement under Section 8(c) of the Employment
Agreement, the Employee's right to terminate the Employment Agreement on such
ground shall be preserved until 10 days after the end of such time period, even
if such ground for termination shall have ceased to exist prior to the end of
such period.

                  2.       Termination Payment.

                  (a) On the Termination Date, and subject to Section 6 herein,

of the August 24, 2000 Agreement (determined by reference to the closing price
of the Employer's Common Stock on the day before the date of the Effective Time,
and (iii) any unpaid salary, bonus (for services through December 31, 2001 only,

Employment Agreement to a bonus for any subsequent year in the event that this
Agreement is terminated as provided in the third sentence of Section 1), expense
reimbursement, previously deferred compensation or vacation pay to which the
Employee may be entitled up to the Termination Date pursuant to the August 24,

                  (b) The amount set forth in Section 2(a) shall be referred to
herein as the "Termination Payment." The Termination Payment shall be reduced by
any required tax withholdings. The Termination Payment shall not be taken into
account as compensation under, and no service credit shall be given after the
Termination Date for purposes of determining the benefits payable under, any
benefit plan, program, agreement or arrangement of the Employer or its
Affiliates. The Employee acknowledges that, except for the Termination Payment
and payments provided under Section 13 of the August 24, 2000 Agreement (and the
other indemnification provisions identified in the final sentence of the first
paragraph of Section 3(b)(i) below), he is not entitled to any payment in the
nature of severance or termination pay from the Employer or any of its
Affiliates and is not entitled to any other amount, payment or benefit, of any
nature whatsoever, from the Employer or any of its Affiliates, including,
without limitation, under any employee benefit plan, program or arrangement of
the Employer or its Affiliates (other than any vested benefit under the
Employer's 401(k) plan) or under the Employment Agreement.

                  3.       General Releases and Waivers

                  (a) General Release and Waiver by Synopsys, Inc., et al
("RELEASE")

                      (i) SYNOPSYS, INC. ("RELEASOR"), on behalf of itself, its
           corporate parents, subsidiaries and Affiliates, including without
           limitation the Employer and its subsidiaries and Affiliates, and its
           directors, managing directors, officers, control persons,
           stockholders, employees, agents, attorneys, administrators,
           successors and assigns (collectively, "RELEASOR"), for good and
           valuable consideration received from the Employee, releases and
           discharges the Employee and his heirs, executors, agents, attorneys,
           administrators, successors and assigns (collectively, "RELEASEE")
           from any claim or cause of action, accounts, agreements, bonds,
           bills, covenants, contracts, controversies, claims, damages, demands,
           debts, dues, extents, executions, judgments, liabilities,
           obligations, promises, predicate acts, reckonings, specialties,
           suits, sums of money, trespasses and variances, including without
           limitation court costs and attorneys fees, in law or in equity, which
           RELEASOR has as of the Execution Date against RELEASEE that are based
           on actions or omissions of RELEASEE occurring prior to the Execution
           Date which, as of the Execution Date (A) are known to RELEASOR, or
           (B) have been disclosed in a publicly available report or other

                                       2
<PAGE>
          document filed on or before the Execution Date with the U.S.
          Securities and Exchange Commission by or on behalf of RELEASEE or the
          Employer, or (C) have been disclosed to RELEASOR by RELEASEE or the
          Employer on or before the Execution Date, the information described in
          (A), (B) and (C) being hereinafter referred to as the "Disclosed
          Facts" (collectively, the "RELEASED MATTERS"). For the purposes of
          this paragraph, a claim against RELEASEE shall be deemed to have
          existed as of the Execution Date if such claim is based upon actions
          or omissions of RELEASEE that occurred or began prior to the Execution
          Date, even if (i) RELEASOR's right to damages or equitable relief on
          such claim had not matured as of the Execution Date; or (2) RELEASOR
          became entitled to additional or different legal or equitable relief
          on such claim after the Execution Date as a result of a continuation
          of the same actions or omissions or the effects thereof, and/or the
          passage of time, after the Execution Date, and such claim shall be
          deemed to include the right to any such additional or different
          relief. "RELEASED MATTERS" do not include any claim that RELEASOR may
          now or hereafter have against the Employee's son, John Hsu, to the
          extent such a claim is based on actions or omissions of John Hsu
          rather than actions or omissions of the Employee.

                      (ii) THE PARTIES ACKNOWLEDGE THAT THEY ARE FAMILIAR WITH
          SECTION 1542 OF THE CIVIL CODE OF THE STATE OF CALIFORNIA, WHICH
          PROVIDES AS FOLLOWS:

                      "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE
          CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
          EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
          AFFECTED HIS SETTLEMENT WITH THE DEBTOR."

                      RELEASOR EXPRESSLY WAIVES AND RELINQUISHES ANY RIGHT OR
           BENEFIT WHICH IT HAS OR MAY HAVE UNDER SECTION 1542 OF THE CIVIL CODE
           OF THE STATE OF CALIFORNIA, OR ANY OTHER STATUTE OR LEGAL PRINCIPLE
           WITH SIMILAR EFFECT WITH RESPECT TO CLAIMS BASED ON OR ARISING FROM
           THE DISCLOSED FACTS, BUT RELEASOR DOES NOT WAIVE OR RELINQUISH ANY
           SUCH RIGHT OR BENEFIT WITH RESPECT TO CLAIMS THAT ARE NOT BASED ON OR
           DO NOT ARISE FROM THE DISCLOSED FACTS.

                      RELEASEE acknowledges that he is aware that, after
           executing this RELEASE, RELEASOR or its attorneys or agents may
           discover facts in addition to or different from the Disclosed Facts,
           and that it is the intention of RELEASOR and RELEASEE not to settle
           and release any claim or cause of action, accounts, agreements,
           bonds, bills, covenants, contracts, controversies, claims, damages,
           demands, debts, dues, extents, executions, judgments, liabilities,
           obligations, promises, predicate acts, reckonings, specialties,
           suits, sums of money, trespasses and variances, including without
           limitation court costs and attorneys fees, in law or in equity, which
           may exist on the basis of facts other than the Disclosed Facts.

                                        3
<PAGE>
                      (iii) The RELEASED MATTERS do not include any claims for
          the breach by RELEASEE or any person or entity acting on his behalf of
          the obligations arising under this Agreement.

                      (iv) Nothing in this Release is intended to, or shall be
          construed or claimed to be, a license in favor of RELEASEE with
          respect to any property of RELEASOR, the Employer, or any other person
          or entity.

                      (v) This RELEASE may not be modified or amended except by
          an instrument in writing signed by the RELEASOR and the RELEASEE.

                  (b) General Release and Waiver by the Employee ("EMPLOYEE
RELEASE").

                      (i) The Employee on behalf of himself, his heirs,
           executors, agents, attorneys, administrators, successors and assigns
           (collectively, "EMPLOYEE RELEASOR"), for good and valuable
           consideration received from the Employer or its Affiliates, hereby
           releases and discharges the Employer, Synopsys and their respective
           subsidiaries and Affiliates and their respective present and former
           directors, managing directors, officers, control persons,
           stockholders, employees, agents, attorneys, administrators,
           successors and assigns (collectively, "SYNOPSYS RELEASEE"), from any
           claim or cause of action, accounts, agreements, bonds, bills,
           covenants, contracts, controversies, claims, damages, demands, debts,
           dues, extents, executions, judgments, liabilities, obligations,
           promises, predicate acts, reckonings, specialties, suits, sums of
           money, trespasses and variances, including without limitation court
           costs and attorneys fees, in law or in equity, which EMPLOYEE
           RELEASOR has as of the Execution Date against SYNOPSYS RELEASEE that
           are based on actions or omissions of SYNOPSYS RELEASEE occurring
           prior to the Execution Date which, as of the Execution Date (A) are
           known to EMPLOYEE RELEASOR; or (B) have been disclosed in a publicly
           available report or other document filed on or before the Execution
           Date with the U.S. Securities and Exchange Commission by or on behalf
           of EMPLOYEE RELEASEE, Synopsys or the Employer, or (C) have been
           disclosed to EMPLOYEE RELEASOR by SYNOPSYS RELEASEE or the Employer
           on or before the Execution Date, the information described in (A),
           (B) and (C) being hereinafter referred to as the "Facts Disclosed to
           EMPLOYEE RELEASOR" (collectively, the "EMPLOYEE RELEASED MATTERS"),
           including, without limitation, under the Americans with Disabilities
           Act of 1990, the Family and Medical Leave Act of 1993, Title VII of
           the United States Civil Rights Act of 1964, 42 U.S.C. Section 1981,
           the California Fair Employment and Housing Act, California's Unruh
           Civil Rights Act, Section 51 of the California Civil Code, the
           California Labor Code, the California Family Rights Act, or any other
           Federal, state, or local law and any workers' compensation or
           disability claims under any such laws. This EMPLOYEE RELEASE relates
           to claims arising from or during Employee's employment relationship
           with the Employer or its Affiliates or as a result of the termination
           of such relationship. The EMPLOYEE RELEASOR further agrees that the
           EMPLOYEE RELEASOR will not file or permit to be filed on EMPLOYEE
           RELEASOR'S behalf any such claim. Notwithstanding the preceding
           sentence or any other provision of this Agreement, this EMPLOYEE
           RELEASE is not intended to interfere with EMPLOYEE RELEASOR's right
           to file a charge with the

                                       4
<PAGE>
          Equal Employment Opportunity Commission in connection with any claim
          EMPLOYEE RELEASOR believes EMPLOYEE RELEASOR may have against SYNOPSYS
          RELEASEE. However, by executing this Agreement, EMPLOYEE RELEASOR
          hereby waives the right to recover in any proceeding EMPLOYEE RELEASOR
          may bring before the Equal Employment Opportunity Commission or any
          state human rights commission or in any proceeding brought by the
          Equal Employment Opportunity Commission or any state human rights
          commission on EMPLOYEE RELEASOR'S behalf. This EMPLOYEE RELEASE is for
          any relief, no matter how denominated, including, but not limited to,
          injunctive relief, wages, back pay, front pay, compensatory damages,
          or punitive damages. This EMPLOYEE RELEASE shall not apply to any
          obligation of the Employer pursuant to this Agreement, Section 13 of
          the August 24, 2000 Agreement or any other right to indemnification
          that the Employee may now or hereafter have under any other
          indemnification agreement with the Employer, statute, or the
          Employer's certificate of incorporation or bylaws.

                      Without limiting the breadth of the preceding paragraph,
           "EMPLOYEE RELEASED MATTERS" shall include any claim, not based on
           Facts Disclosed to EMPLOYEE RELEASOR, that EMPLOYEE RELEASOR may now
           or hereafter have against SYNOPSYS RELEASEE based on any transaction
           described in Item 404 of Regulation S-K under the Exchange Act
           involving or relating to the Employer or any of its "subsidiaries"
           (as such term is defined in Rule 12b-2 under the Exchange Act) (i) to
           which the Employee or any member of his "immediate family" (as such
           term is defined in Rule 16a-1 under the Exchange Act) is presently a
           party, or (ii) in which the Employee presently has any "pecuniary
           interest" (as such term is defined in the next sentence). For
           purposes of this paragraph, the term "pecuniary interest" means the
           opportunity, directly or indirectly, to profit or share in any profit
           derived from a transaction, including any "indirect pecuniary
           interest" (as such term is defined in Rule 16a-1 under the Exchange
           Act) and, for purposes of clarification, determined without regard to
           whether the transaction involves any securities of the Employer or
           any subsidiary. The Employee shall be liable to the Employer for any
           damages resulting to the Employer from a transaction to which the
           first sentence of this paragraph applies, but only to the extent of
           the Employee's pecuniary interest in such transaction and only if the
           facts concerning such transaction are not Disclosed Facts.

                      "EMPLOYEE RELEASED MATTERS" does not include any claim
           that any heir of the Employee may now or hereafter have against
           SYNOPSYS RELEASEE, except for any such claim that is based solely on
           the status of such person as an heir of the Employee.

                      (ii) THE PARTIES ACKNOWLEDGE THAT THEY ARE FAMILIAR WITH
          SECTION 1542 OF THE CIVIL CODE OF THE STATE OF CALIFORNIA, WHICH
          PROVIDES AS FOLLOWS:

                      "A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE
          CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
          EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM MUST HAVE MATERIALLY
          AFFECTED HIS SETTLEMENT WITH THE DEBTOR."

<PAGE>
                      EMPLOYEE RELEASOR, HAVING READ AND UNDERSTOOD SECTION 1542
           AND BEEN ADVISED BY HIS OWN COUNSEL CONCERNING SECTION 1542 AND THE
           LEGAL EFFECT OF A WAIVER THEREOF, EXPRESSLY WAIVES AND RELINQUISHES
           ANY RIGHT OR BENEFIT WHICH HE HAS OR MAY HAVE UNDER SECTION 1542 OF
           THE CIVIL CODE OF THE STATE OF CALIFORNIA, OR ANY OTHER STATUTE OR
           LEGAL PRINCIPLE WITH SIMILAR EFFECT WITH RESPECT TO CLAIMS BASED ON
           OR ARISING FROM FACTS DISCLOSED TO EMPLOYEE RELEASOR, BUT EMPLOYEE
           RELEASOR DOES NOT WAIVE OR RELINQUISH ANY SUCH RIGHT OR BENEFIT WITH
           RESPECT TO CLAIMS THAT ARE NOT BASED ON OR DO NOT ARISE FROM FACTS
           DISCLOSED TO EMPLOYEE RELEASOR.

                       SYNOPSYS RELEASEE acknowledges that it is aware that,
           after executing this EMPLOYEE RELEASE, EMPLOYEE RELEASOR or his
           attorneys or agents may discover facts in addition to or different
           from the Facts Disclosed to EMPLOYEE RELEASOR, and that it is the
           intention of EMPLOYEE RELEASOR and SYNOPSYS RELEASEE not to settle
           and release any claim or cause of action, accounts, agreements,
           bonds, bills, covenants, contracts, controversies, claims, damages,
           demands, debts, dues, extents, executions, judgments, liabilities,
           obligations, promises, predicate acts, reckonings, specialties,
           suits, sums of money, trespasses and variances, including without
           limitation court costs and attorneys fees, in law or in equity, which
           may exist on the basis of facts other than the Facts Disclosed to
           EMPLOYEE RELEASOR.

                      (iii) This EMPLOYEE RELEASE may not be modified or amended
          except by an instrument in writing signed by the EMPLOYEE RELEASOR and
          the SYNOPSYS RELEASEE.

                      (iv) The EMPLOYEE RELEASED MATTERS do not include any
          claims for the breach by any person other than the Employee of
          obligations arising under this Agreement.

                  4.       Restrictive Covenants

                  The Employee hereby agrees and acknowledges that the Employee
shall be bound by and shall comply with the restrictive covenants provided in
Sections 16 and 17 of the August 24, 2000 Agreement and that such restrictive
covenants are hereby made a part of this Agreement as if specifically restated
herein, subject in each case to all of the terms and conditions of such Sections
16 and 17 except as expressly provided below in this section, provided that, the
Employee hereby agrees that, (a) with respect to Section 17 of the August 24,
2000 Agreement, (i) he shall not engage in any of the restricted activities
listed under Section 17 of the August 24, 2000 Agreement for a period of four
years from the Termination Date, (ii) clause 17(a)(i) shall be amended to read
as follows:

                  (i) Become an officer, director, partner, associate, employee,
         owner, agent, creditor, independent contractor, co-venturer or
         otherwise, or be interested in or associated with any other
         corporation, firm or business engaged, in any geographical area

                                       6
<PAGE>
         in which the Employer, Synopsys or their respective subsidiaries and
         Affiliates (the "Synopsys Group") is then engaged, in making or selling
         one or more products competitive with a product or products then being
         made or sold by the Synopsys Group in the EDA industry, which products
         made or sold by the Synopsys Group accounted for at least 1% of the
         annual sales of either the Corporation or Synopsys (including in each
         case their respective subsidiaries and affiliates) during the four
         fiscal quarter period ending with the last fiscal quarter completed
         prior to the Termination Date;

                   and (iii) clause 17(a)(iv) shall be amended by replacing the
word "executive" in line three thereof with the word "employee", and by adding
the following at the end of such clause 17(a)(iv): ", nor to any solicitation of
Yvonne Liu (commencing six months after the Termination Date), Kevin Liu, David
Huang, D.J. Ma, Maggie Chen, C.S. Kuo or any relative of the Employee; and (b)
the obligation not to disclose confidential information, as described under
Section 16 of the August 24, 2000 Agreement, shall not terminate on the first
anniversary of the Termination Date with respect to trade secrets related to the
Employer's technology or financial information, or to the pricing or other
material terms or conditions of agreements between the Employer and any of its
customers, but shall instead continue until the fourth anniversary of the
Termination Date with respect to such trade secrets. The Employee agrees and
acknowledges that the Proprietary Information and Inventions Agreement executed
by him continues in full force and effect in accordance with its terms, except
to the extent that Sections 4(a) and 4(b) of this Agreement expressly state a
more limited scope or duration of the Employee's obligations not to disclose the
Employer's confidential information or to compete with the Employer or the
Synopsys Group. The restrictions imposed on the Employee's activities under
Section 17 of the August 24, 2000 Agreement, as incorporated by reference in and
amended by this Agreement, shall not be interpreted to restrict any activities
of the Employee that are not materially related to the EDA industry, nor to the
Employee's donation of any money, property or services to any educational,
scientific or religious organization as defined in Section 501(c)(3) of the
Internal Revenue Code, as amended (or any such organization that would fall
within such definition if the entire world were part of the United States).

                  The Employee hereby agrees that it is impossible to measure in
money the damages which will accrue to the Employer, Synopsys or their
respective subsidiaries and Affiliates (the "Synopsys Group") by reason of a
failure by the Employee to perform any of his obligations under the restrictive
covenants. Accordingly, notwithstanding Section 11 of this Agreement, if the
Synopsys Group institutes any action or proceeding to enforce the provisions
hereof, to the extent permitted by applicable law, the Employee hereby waives
the claim or defense that the Synopsys Group has an adequate remedy at law, and
the Employee shall not urge in any such action or proceeding the claim or
defense that any such remedy at law exists.

                  5. [intentionally omitted]

                  6. Certain Forfeitures in Event of Breach

                  The Employee acknowledges and agrees that, notwithstanding any
other provision of this Agreement, in the event the Employee breaches any of his
obligations under Section 4(a) of this Agreement relating to Section 17 of the
August 24, 2000 Agreement, the Employee will forfeit his right to receive the
Termination Payment under Section 2 of this Agreement to the

                                       7
<PAGE>
extent not theretofore paid to him as of the date of such breach and, if already
made as of the time of breach, the Employee agrees that he will reimburse the
Employer, immediately, for the amount of such payment. The preceding sentence
states the Employer's exclusive monetary remedy for such a breach. In no event
shall the Employee's aggregate liability for any breach or breaches of any
obligations under this Agreement exceed the amount of the Termination Payment
received by him.

                  7. Cooperation in Certain Litigation Matters

                  From the Termination Date through the earliest to occur of the
fifth anniversary thereof, the Employee's death or the Employee's disability, or
such other time as the Parties may mutually agree, the Employee agrees to
cooperate with the Synopsys Group as the Synopsys Group may from time to time
request in connection with certain litigation matters relating to the Employer,
not to exceed an aggregate of 10 business days in any month, unless the Parties
otherwise agree, provided that the nature and timing of the cooperation
requested is reasonable. To the extent such cooperation can reasonably be
provided by telephone, the time spent providing such cooperation by telephone
shall be aggregated on the basis that eight hours constitutes one business day.
Such cooperation shall relate to litigation pending as of the Termination Date
involving the Employer or its Affiliates and any other litigation relating to
events or circumstances existing or occurring during the Employee's period of
employment as to which the Synopsys Group requests the Employee's cooperation:

                                    (A) cooperation in regard to such litigation
                provided, however, notwithstanding the occurrence of the fifth
                anniversary of the Termination Date the Employee's agreement to
                cooperate respecting such litigation shall continue for the
                duration of such litigation and the Employee shall be provided
                reasonable additional compensation agreed to by the Parties for
                such cooperation as the Employee may provide;

                                    (B) if requested by the Synopsys Group, such
                cooperation shall include, without limitation, (1) responding
                promptly to requests for information and documents in the
                Employee's possession concerning matters pertinent to any of the
                foregoing, (2) making himself available as a witness and
                testifying at trial, depositions, hearings or other proceedings,
                as well as being available for adequate preparation for such
                testimony; and (3) participating at times in interviews and
                meetings with representatives of the Synopsys Group,
                representatives of governments or regulatory authorities, or
                others designated by the Synopsys Group;

                                    (C) unless prohibited by applicable law or
                any rule of any applicable regulatory authority, the Employee
                further agrees to notify the Employer and Synopsys promptly of
                any request made to the Employee by any party to any such
                litigations for information or assistance with respect to such
                litigations, and the substance of the Employee's response to
                such request. The Employee shall also provide the Employer and
                Synopsys with a copy of such request and response, if in
                writing;

                                       8
<PAGE>
                                    (D) the Employee and the Synopsys Group will
                each use good faith best efforts to reconcile and accommodate
                any conflicts in scheduling such cooperation described above,
                the Synopsys Group taking into account previously scheduled
                vacation or personal plans of the Employee and the Employee
                taking into account the Synopsys Group's need to comply with
                judicial or other schedules; and

                                    (E) in respect of all cooperation provided
                by the Employee hereunder, the Employer shall pay all of the
                Employee's reasonable out-of-pocket expenses in connection
                therewith promptly upon the Employee's presentation to the
                Employer of an invoice specifying the amount and purpose of the
                expense.

                  8.       No Admission

                  This Agreement does not constitute an admission of liability
or wrongdoing of any kind by any member of the Synopsys Group, including the
Employer or its Affiliates.

                  9.       Indemnification

                  The Parties hereby agree and acknowledge that they shall be
bound by Section 13 of the August 24, 2000 Agreement. The Employee shall not
unreasonably withhold his consent to the settlement of any litigation or other
proceeding as to which the Employee is indemnified under such Section 13,
provided that such settlement will not require payment of any material amount by
the Employee or otherwise result in a material detriment to the Employee.

                  10.      Heirs and Assigns

                  The terms of this Agreement shall be binding on the Parties
hereto and their respective successors and assigns.

                  11.      Arbitration

                  The Parties hereby agree and acknowledge that they shall be
bound by Section 14 of the August 24, 2000 Agreement.

                  12.      General Provisions

                  (a)      Notice

day after it is sent by a reputable overnight courier service and, in each case,
addressed as follows (or if it is sent through any other method agreed upon by

                  (b)      Integration

                  This Agreement constitutes the entire understanding of the
Synopsys Group and the Employee with respect to the subject matter hereof and
supersedes all prior understandings, written or oral, including the Employment
Agreement (except for Sections 13, 14, 16 and 17 of the August 24, 2000
Agreement, which shall remain in effect as provided herein). The terms of this
Agreement may be changed, modified or discharged only by an instrument in
writing signed by the Parties hereto. A failure of the Synopsys Group or the
Employee to insist on strict compliance with any provision of this Agreement
shall not be deemed a waiver of such provision or any other provision hereof. In
the event that any provision of this Agreement is determined to be so broad as
to be unenforceable, such provision shall be interpreted to be only so broad as
is enforceable.

                  (c)      Choice of Law

                  THIS AGREEMENT SHALL BE CONSTRUED, ENFORCED AND INTERPRETED IN

                  The Parties hereto acknowledge and agree that each Party has
reviewed and negotiated the terms and provisions of this Agreement and has had
the opportunity to contribute to its revision. Accordingly, the rule of
construction to the effect that ambiguities are resolved against the drafting
party shall not be employed in the interpretation of this Agreement. Rather, the
terms of this Agreement shall be construed fairly as to both Parties hereto and
not in favor or against either Party.

                  This Agreement may be executed in any number of counterparts
and by different Parties on separate counterparts, each of which counterpart,
when so executed and delivered, shall be deemed to be an original and all of
which counterparts, taken together, shall constitute but one and the same
Agreement.
