                                AND PRIVILEGES OF

                            SERIES A PREFERRED STOCK

                                       OF

                               SYNC RESEARCH, INC.

Pursuant to Section 151 of the General Corporation Law of the State of Delaware:

         I, William K. Guerry, President and Chief Financial Officer of Sync
Research, Inc., a corporation organized and existing under the General
Corporation Law of the State of Delaware, in accordance with the provisions of
Section 103 thereof, DO HEREBY CERTIFY:

         That pursuant to the authority conferred upon the Board of Directors by
the Certificate of Incorporation of the said Corporation, the said Board of
Directors on May 9, 2000 adopted the following resolution creating a series of
shares of Preferred Stock designated as Series A Preferred Stock:

         "RESOLVED, that pursuant to the authority vested in the Board of
Directors of the corporation by the Certificate of Incorporation, the Board of
Directors does hereby provide for the issue of a series of Preferred Stock,
$0.001 par value, of the Corporation, to be designated "Series A Preferred
Stock", initially consisting of seven hundred thousand (700,000) shares and to
the extent that the designations, powers, preferences and relative and other
special rights and the qualifications, limitations and restrictions of the
Series A Preferred Stock are not stated and expressed in the Certificate of
Incorporation, does hereby fix and herein state and express such designations,
powers, preferences and relative and other special rights and the
qualifications, limitations and restrictions thereof, as follows (all terms used
herein which are defined in the Certificate of Incorporation shall be deemed to
have the meanings provided therein):

         Section 1. DESIGNATION AND AMOUNT. The shares of such series shall be
designated as "Series A Preferred Stock", par value $0.001 per share, and the
number of shares constituting such series shall be seven hundred thousand
(700,000).

         Section 2. DIVIDEND PROVISION. The holders of shares of Series A
Preferred Stock shall be entitled to receive cumulative dividends, out of any
assets legally available therefor, prior and in preference to any declaration or
payment of any dividend (payable other than in Common Stock or other securities
and rights convertible into or entitling the holder thereof to receive, directly
or indirectly, additional shares of Common Stock of the Corporation) on the
Common Stock of the Corporation, at the rate of six percent (6%) per annum,
which initially equals $0.191625 per share (as adjusted for stock splits, stock
dividends, reclassification and the like) per annum on each outstanding share of
Series A Preferred Stock, when and as declared

<PAGE>

by the Board of Directors or upon the event of any liquidation, dissolution
or winding up of the Corporation. Such dividends shall accumulate on each
share of Series A Preferred Stock from and after May 12, 2000, and shall
accumulate from day to day, whether or not earned or declared. Such dividends
shall be cumulative so that, except as provided below, if such dividends in
respect of any previous or current dividend period, at the rate specified
above, shall not have been paid the deficiency shall first be fully paid
before any dividend or other distribution shall be paid on or declared and
set apart for the Common Stock. Any accumulation of dividends on the Series A
Preferred Stock shall not bear interest. Dividends that have accumulated with
respect to a share of Series A Preferred Stock but have not been declared
shall, upon conversion of such share to Common Stock except in connection
with the Osicom Merger, be deemed declared and payable. No dividends shall
accumulate on any share of Series A Preferred Stock after conversion of such
share to Common Stock.

         Section 3.        LIQUIDATION; ACQUISITIONS.

                  (a) PREFERENCE. In the event of any liquidation, dissolution
or winding up of the Corporation, either voluntary or involuntary, the holders
of the Series A Preferred Stock shall be entitled to receive, prior and in
preference to any distribution of any of the assets of the Corporation to the
holders of Common Stock by reason of their ownership thereof, an amount per
share equal to $3.19375 per share (as adjusted for stock splits, stock
dividends, reclassification and the like) for each share of Series A Preferred
Stock then held by them, plus accumulated but unpaid dividends. Accumulated
dividends on the Series A Preferred Stock shall be deemed to be declared by the
Board of Directors upon an event of liquidation, dissolution or winding up of
the Corporation, but shall not be deemed to be declared by the Board of
Directors upon the Osicom Merger. If, upon the occurrence of such liquidation,
dissolution or winding up of the Corporation, the assets and funds thus
distributed among the holders of the Series A Preferred Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then, the entire assets and funds of the Corporation
legally available for distribution shall be distributed ratably among the
holders of the Series A Preferred Stock in proportion to the preferential amount
each such holder is otherwise entitled to receive.

                  (b)      REMAINING ASSETS. Upon the completion of the
distribution required by Section 2(a) above and any other distribution that
may be required with respect to series of Preferred Stock that may from time
to time come into existence, if assets remain in the Corporation, the holders
of the Common Stock of the Corporation shall receive all of the remaining
assets of the Corporation.

                  (c)      ACQUISITION EVENTS.

                            (i) An Acquisition of the Corporation other than the
Osicom Merger shall be deemed to be a liquidation, dissolution or winding up for
purposes of Section 2 and Section 3. The Osicom Merger shall not be treated as a
liquidation, dissolution or winding up for purposes of Section 2 or 3, but shall
instead be treated pursuant to Section 4(b) hereof. For purposes of this
Certificate of Designation, "ACQUISITION" shall mean (A) the consummation of the
transactions (the "OSICOM MERGER") contemplated by that certain Agreement and
Plan of Merger

                                      -2-
<PAGE>

by and among the Corporation, Merger Co, a Delaware corporation and
wholly-owned subsidiary of the Corporation, Osicom Technologies, Inc. a
Delaware corporation ("OSICOM") and Osicom Technologies, Inc., a New Jersey
corporation ("OSICOM NEW JERSEY"), dated April 10, 2000, as may be amended by
the parties thereto (the "OSICOM MERGER AGREEMENT"), (B) the sale, conveyance
or disposal, of all or substantially all of the Corporation's property or
business, (C) the Corporation's merger into or consolidation with any other
corporation other than a merger effected exclusively for the purpose of
changing the domicile of the Corporation, or (D) any other transaction or
series of related transactions in which the Corporation's stockholders of
record as constituted immediately prior to such transaction or series of
related transactions will, immediately after such transaction or series of
related transactions (by virtue of securities issued as consideration in the
transaction or series of related transactions or otherwise) hold less than a
majority of the voting power of the surviving entity (or its successor or
parent).

       Section 4. CONVERSION. The holders of the Series A Preferred Stock shall
have conversion rights as follows (the "CONVERSION RIGHTS"):

                  (a) RIGHT TO CONVERT. Subject to Section 4(c), each share of
Series A Preferred Stock shall be convertible, at the option of the holder
thereof, at any time after the date of issuance of such share, at the office of
the Corporation or any transfer agent for such stock, into such number of fully
paid and nonassessable shares of Common Stock as is determined by dividing
$3.19375 by the Conversion Price applicable to such share, determined as
hereafter provided, in effect on the date the certificate is surrendered for
conversion. The initial Conversion Price per share of Series A Preferred Stock
shall be $3.19375. Such initial Conversion Price shall be subject to adjustment
as set forth in Section 4(d).

                  (b) AUTOMATIC CONVERSION. Each share of Series A Preferred
Stock shall automatically be converted , without any further action of any
party, into shares of Common Stock at the Conversion Price at the time in effect
for such share immediately upon the earlier of (i) the date specified by the
consent or agreement in writing of the Company and the holders of a majority of
the then outstanding shares of Series A Preferred Stock, or (ii) immediately
prior to the effective time of the Osicom Merger.

                  (c) MECHANICS OF CONVERSION. Subject to Section 4(b), before
any holder of Series A Preferred Stock shall be entitled to convert the same
into shares of Common Stock, such holder shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or of any
transfer agent for such series of Preferred Stock, and shall give written notice
to the Corporation at its principal corporate office, of the election to convert
the same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. The Corporation shall,
as soon as practicable thereafter, cause the transfer agent to issue and deliver
at such office to such holder of Preferred Stock, or to the nominee or nominees
of such holder, a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled as aforesaid. Such conversion shall
be deemed to have been made immediately prior to the close of business on the
date of such surrender of the shares of such series of Preferred Stock to be
converted, and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be

                                      -3-
<PAGE>

treated for all purposes as the record holder or holders of such shares of
Common Stock as of such date.

                  (d) CONVERSION PRICE ADJUSTMENTS OF PREFERRED STOCK FOR SPLITS
AND COMBINATIONS. The Conversion Price of the Series A Preferred Stock shall be
subject to adjustment from time to time as follows:

                            (i) STOCK SPLITS AND DIVIDENDS. In the event the
Corporation should at any time or from time to time after the date on which
shares of Series A Preferred Stock are first issued (the "PURCHASE DATE") fix a
record date for the effectuation of a split or subdivision of the outstanding
shares of Common Stock or the determination of holders of Common Stock entitled
to receive a dividend or other distribution payable in additional shares of
Common Stock or other securities or rights convertible into, or entitling the
holder thereof to receive directly or indirectly, additional shares of Common
Stock (hereinafter referred to as "COMMON STOCK EQUIVALENTS") without payment of
any consideration by such holder for the additional shares of Common Stock or
the Common Stock Equivalents (including the additional shares of Common Stock
issuable upon conversion or exercise thereof), then, as of such record date (or
the date of such dividend distribution, split or subdivision if no record date
is fixed), the Conversion Price of the Series A Preferred Stock shall be
appropriately decreased so that the number of shares of Common Stock issuable on
conversion of each share of such series shall be increased in proportion to such
increase of the aggregate of shares of Common Stock outstanding and those
issuable with respect to such Common Stock Equivalents with the number of shares
issuable with respect to Common Stock Equivalents determined from time to time
as provided in Section 4(d)(iii) below.

                            (ii) REVERSE STOCK SPLITS. If the number of shares
of Common Stock outstanding at any time after the Purchase Date is decreased by
a combination of the outstanding shares of Common Stock, then, following the
record date of such combination, the Conversion Price for the Series A Preferred
Stock shall be appropriately increased so that the number of shares of Common
Stock issuable on conversion of each share of such series shall be decreased in
proportion to such decrease in outstanding shares.

                            (iii) The following provisions shall apply for
purposes of this Section 4(d):

                                   (A) The aggregate maximum number of shares of
Common Stock deliverable upon conversion or exercise of Common Stock Equivalents
(assuming the satisfaction of any conditions to convertibility or
exercisability, including, without limitation, the passage of time, but without
taking into account potential antidilution adjustments) shall be deemed to have
been issued at the time such Common Stock Equivalents were issued.

                                   (B) In the event of any change in the number
of shares of Common Stock deliverable or in the consideration payable to the
Corporation upon conversion or exercise of such Common Stock Equivalents
including, but not limited to, a change resulting from the antidilution
provisions thereof, the Conversion Price of the Series A

                                      -4-
<PAGE>

Preferred Stock, to the extent in any way affected by or computed using such
Common Stock Equivalents, shall be recomputed to reflect such change, but no
further adjustment shall be made for the actual issuance of Common Stock or
any payment of such consideration upon the exercise of any such options or
rights or the conversion or exchange of such securities.

                                   (C) Upon the termination or expiration of
the convertibility or exercisability of any such Common Stock Equivalents,
the Conversion Price of the Series A Preferred Stock, to the extent in any
way affected by or computed using such Common Stock Equivalents, shall be
recomputed to reflect the issuance of only the number of shares of Common
Stock (and Common Stock Equivalents which remain convertible or exercisable)
actually issued upon the conversion or exercise of such Common Stock
Equivalents.

                             (e) OTHER DISTRIBUTIONS. In the event the
Corporation shall declare a distribution payable in securities of other
persons, evidences of indebtedness issued by the Corporation or other
persons, assets (excluding cash dividends) or options or rights not referred
to in Section 4(d)(i), then, in each such case for the purpose of this
Section 4(e), the holders of Series A Preferred Stock shall be entitled to a
proportionate share of any such distribution as though they were the holders
of the number of shares of Common Stock of the Corporation into which their
shares of Preferred Stock are convertible as of the record date fixed for the
determination of the holders of Common Stock of the Corporation entitled to
receive such distribution.

                             (f) RECAPITALIZATIONS. If at any time or from
time to time there shall be a recapitalization of the Common Stock (other
than an Acquisition or a subdivision or combination provided for elsewhere in
this Certificate of Designation), provision shall be made so that the holders
of the Series A Preferred Stock shall thereafter be entitled to receive upon
conversion of such Preferred Stock the number of shares of stock or other
securities or property of the Corporation or otherwise, to which a holder of
Common Stock deliverable upon conversion would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in
the application of the provisions of this Section 4 with respect to the
rights of the holders of such Preferred Stock after the recapitalization to
the end that the provisions of this Section 4 (including adjustment of the
Conversion Price then in effect and the number of shares purchasable upon
conversion of such Preferred Stock) shall be applicable after that event and
be as nearly equivalent as practicable.

                             (g) NO FRACTIONAL SHARES AND CERTIFICATE AS TO
ADJUSTMENTS.

                                   (i) No fractional shares shall be issued upon
the conversion of any share or shares of the Series A Preferred Stock, and the
number of shares of Common Stock to be issued shall be rounded down to the
nearest whole share. The number of shares issuable upon such conversion shall be
determined on the basis of the total number of shares of Series A Preferred
Stock the holder is at the time converting into Common Stock and the number of
shares of Common Stock issuable upon such aggregate conversion.

                                   (ii) Upon the occurrence of each adjustment
or readjustment of the Conversion Price of Series A Preferred Stock pursuant to
this Section 4, the Corporation, at

                                      -5-
<PAGE>

its expense, shall promptly compute such adjustment or readjustment in
accordance with the terms hereof and prepare and furnish to each holder of
such Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of Series A Preferred Stock, furnish or cause to be
furnished to such holder a like certificate setting forth (A) such adjustment
and readjustment, (B) the Conversion Price for the Series A Preferred Stock
at the time in effect, and (C) the number of shares of Common Stock and the
amount, if any, of other property which at the time would be received upon
the conversion of a share of the Series A Preferred Stock.

                            (h) NOTICES OF RECORD DATE. In the event of any
taking by the Corporation of a record of the holders of any class of
securities for the purpose of determining the holders thereof who are
entitled to receive any dividend (other than a cash dividend) or other
distribution, any right to subscribe for, purchase or otherwise acquire any
shares of stock of any class or any other securities or property, or to
receive any other right, or an Acquisition, or in the event of a proposed
liquidation, dissolution or winding up of the Corporation, the Corporation
shall give notice to each holder of Series A Preferred Stock of the proposed
dividend, distribution, right, or proposed Acquisition or liquidation,
dissolution or winding up.

                            (i) RESERVATION OF STOCK ISSUABLE UPON
CONVERSION. The Corporation shall at all times reserve and keep available out
of its authorized but unissued shares of Common Stock, solely for the purpose
of effecting the conversion of the shares of the Series A Preferred Stock,
such number of its shares of Common Stock as shall from time to time be
sufficient to effect the conversion of all outstanding shares of such series
of Preferred Stock; and if at any time the number of authorized but unissued
shares of Common Stock shall not be sufficient to effect the conversion of
all then outstanding shares of such series of Preferred Stock, in addition to
such other remedies as shall be available to the holder of such Preferred
Stock, the Corporation will take such corporate action as may, in the opinion
of its counsel, be necessary to increase its authorized but unissued shares
of Common Stock to such number of shares as shall be sufficient for such
purposes, including, without limitation, engaging in best efforts to obtain
the requisite stockholder approval of any necessary amendment to the
Corporation's Certificate of Incorporation.

                            (j) NOTICES. Any notice required by this
Certificate of Designation to be given to the holders of shares of Series A
Preferred Stock shall be deemed given : (i) if delivered personally, on the
date of delivery, (ii) if delivered by confirmed facsimile transmission, on
the date of such confirmation of receipt, (iii) if by overnight express
courier, on the business day after the date of deposit with such courier, and
(iv) if by U.S. mail, five business days after deposit in the United States
mail, postage prepaid, and in each case addressed to each holder of record at
his address appearing on the books of the Corporation.

         Section 5. VOTING RIGHTS. The holder of each share of Series A
Preferred Stock shall have the right to one vote for each share of Common
Stock into which such Preferred Stock could then be converted, and with
respect to such vote, such holder shall have full voting rights and powers
equal to the voting rights and powers of the holders of Common Stock, and
shall be

                                      -6-
<PAGE>

entitled, notwithstanding any provision hereof, to notice of any
stockholders' meeting in accordance with the bylaws of the Corporation, and
shall be entitled to vote, together with holders of Common Stock as a single
class on an as-converted basis, with respect to any question upon which
holders of Common Stock have the right to vote. Fractional votes shall not,
however, be permitted and any fractional voting rights available on an
as-converted basis (after aggregating all shares into which shares of Series
A Preferred Stock held by each holder could be converted) shall be rounded
down to the next lowest whole number.

          Section 6. STATUS OF CONVERTED STOCK. In the event any shares of
Preferred Stock shall be converted pursuant to Section 4 hereof, the shares so
converted shall be cancelled and shall not be issuable by the Corporation.

          Section 7. NO REDEMPTION. The shares of Series A Preferred Stock
shall not be redeemable.

                                      -7-

to the Company and agrees with the Company that, as of the date of this
Agreement and as of the Closing Date:

       2.1    AUTHORIZATION; ENFORCEABILITY. The Purchaser is duly and validly
organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation or organization with full power and authority
to purchase the Shares and to execute and deliver this Agreement. This Agreement
constitutes the Purchaser's valid and legally binding obligation, enforceable in
accordance with its terms, except as such enforcement may be limited by (i)
applicable bankruptcy, insolvency, reorganization or other laws of general
application relating to or affecting the enforcement of creditors' rights
generally and (ii) general principles of equity.

       2.2    ACCREDITED INVESTOR; INVESTMENT INTENT. The Purchaser is an
accredited investor as that term is defined in Rule 501 of Regulation D, and is
acquiring the Shares solely for its own account for investment purposes as a
principal and not with a present view to the public resale or distribution of
all or any part thereof, except pursuant to sales that are exempt from the
registration requirements of the Securities Act or sales registered under the
Securities Act; provided, however that in making such representation, the
Purchaser does not agree to hold the Shares for any minimum or specific term and
reserves the right to sell, transfer or otherwise dispose of the Shares at any
time in accordance with the provisions of this Agreement and with Federal and
state securities laws applicable to such sale, transfer or disposition.

       2.3    INFORMATION. The Company has provided the Purchaser with
information regarding the business, operations and financial condition of the
Company, and has granted to the Purchaser the opportunity to ask questions of
and receive answers from representatives of the Company, its officers,
directors, employees and agents concerning the Company and materials relating to
the terms and conditions of the purchase and sale of the Shares hereunder.

       2.4    LIMITATIONS ON DISPOSITION. The Purchaser acknowledges that,
except as provided in the Registration Rights Agreement, the Shares and the
Registrable Shares have not been and are not being registered under the
Securities Act and may not be transferred or resold without registration under
the Securities Act or unless pursuant to an exemption therefrom.

                                      -2-
<PAGE>

       2.5    LEGEND. The Purchaser understands that the certificates
representing the Shares and any Registrable Shares will bear at issuance a
restrictive legend in substantially the following form:

                  "The securities represented by this certificate have not been
                  registered under the Securities Act of 1933, as amended (the
                  "SECURITIES ACT"), or the securities laws of any state, and
                  may not be offered or sold unless a registration statement
                  under the Securities Act and applicable state securities laws
                  shall have become effective with regard thereto, or an
                  exemption from registration under the Securities Act and
                  applicable state securities laws is available in connection
                  with such offer or sale. The securities are subject to the
                  provisions of a Stock Purchase Agreement dated May 12, 2000
                  between the Company and Entrada Holdings LLC with respect to
                  voting."

        Notwithstanding the foregoing, it is agreed that, as long as (A) the
resale or transfer (including without limitation a pledge) of any of the

term "AFFILIATE" or "AFFILIATED" shall mean a person that directly, or
indirectly through one or more intermediaries, controls, or is controlled by,
or is under common control with, the Purchaser. The term "LOSS" or "LOSSES"
shall mean any and all legal fees and related expenses reasonably incurred by
such Indemnitee in connection with the defense of or any proceeding with
respect to any claims, whether accrued,

                                      -12-
<PAGE>

contingent or otherwise, resulting from or arising out of the purchase and
ownership by the Purchaser of the Shares and the Registrable Shares and in
which Indemnitee is named as a defendant, provided however that "LOSS" and
"LOSSES" shall not mean any judgments, damages or amounts paid in settlement
of any claim.

         (b) Any party who receives notice of a potential claim that may, in the
judgment of such party, result in a Loss shall use all reasonable efforts to
provide the parties hereto notice thereof in the manner provided herein,
provided that failure or delay or alleged delay in providing such notice shall
not adversely affect such party's right to indemnification hereunder unless such
failure materially prejudices Indemnitor's ability to coordinate the defense of
any such claim. In the event that any party shall incur or suffer any Losses in
respect of which indemnification may be sought by such party hereunder, the
Indemnitee shall assert a claim for indemnification by written notice (a
"NOTICE") to the Indemnitor stating the nature and basis of such claim in
reasonable detail, which Notice shall be given within 30 days of the filing of
the proceeding in which Indemnitee is named as a defendant, but the failure of
the Indemnitee to give the Notice within such time period shall not relieve the
Indemnitor of any liability that the Indemnitor may have to the Indemnitee,
unless such failure materially prejudices Indemnitor's ability to coordinate the
defense of such claim.

         (c) The Losses in respect of such claims shall be borne and paid by the
Indemnitor, and the Indemnitor shall pay the Indemnitee, in immediately
available funds, as such Losses are incurred, as evidenced by itemized bills for
Losses to such Indemnitee. The parties agree to cooperate fully with one another
in connection with the defense of any such claims.

         (d) The remedies provided for in this Agreement shall not be exclusive
of any other rights or remedies available to one party against the other, either
at law or in equity.

         (e) The provisions of this Section 6.6 shall survive the Closing.

7.       MISCELLANEOUS.

         7.1 SURVIVAL; SEVERABILITY. The representations, warranties, covenants
and indemnities made by the parties herein shall survive the Closing
notwithstanding any due diligence investigation made by or on behalf of the
party seeking to rely thereon. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, this Agreement shall continue in full force and effect
without said provision; provided that in such case the parties shall negotiate
in good faith to replace such provision with a new provision which is not
illegal, unenforceable or void, as long as such new provision does not
materially change the economic benefits of this Agreement to the parties.

         7.2 SUCCESSORS AND ASSIGNS. The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the respective successors and
permitted assigns of the parties. Nothing in this Agreement, express or implied,
is intended to confer upon any party other than the parties hereto or their
respective successors and permitted assignors any rights, remedies, obligations
or liabilities under or by reason of this Agreement, except as expressly

                                      -13-
<PAGE>

provided in this Agreement. The Purchaser may assign its rights and
obligations hereunder, in connection with any private sale or transfer of the
Shares in accordance with the terms hereof, as long as, as a condition
precedent to such transfer, (i) the transferee executes an acknowledgment
agreeing to be bound by the applicable provisions of this Agreement
(including but not limited to the Purchaser's obligations under Section 6.1)
in which case the term "Purchaser" shall be deemed to refer to such
transferee as though such transferee were an original signatory hereto and
(ii) the Board of Directors of the Company reasonably deems that the proposed
transferee is not a competitor of the Company. The Company may not assign its
rights or obligations under this Agreement.

         7.3 NO RELIANCE. Each party acknowledges that (i) it has such knowledge
in business and financial matters as to be fully capable of evaluating this
Agreement, the other Transaction Documents and the transactions contemplated
hereby and thereby, (ii) it is not relying on any advice or representation of
the other party in connection with entering into this Agreement, the other
Transaction Documents or such transactions (other than the representations made
in this Agreement or the other Transaction Documents), (iii) it has not received
from such party any assurance or guarantee as to the merits (whether legal,
regulatory, tax, financial or otherwise) of entering into this Agreement or the
other Transaction Documents or the performance of its obligations hereunder and
thereunder, and (iv) it has consulted with its own legal, regulatory, tax,
business, investment, financial and accounting advisors to the extent that it
has deemed necessary, and has entered into this Agreement and the other
Transaction Documents based on its own independent judgment and on the advice of
its advisors as it has deemed necessary, and not on any view (whether written or
oral) expressed by such party.

         7.4 GOVERNING LAW; JURISDICTION. This Agreement shall be governed by
and construed under the laws of the State of California without regard to the
conflict of laws provisions thereof. Each party hereby irrevocably submits to
the exclusive jurisdiction of the state and federal courts sitting in the State
of California, for the adjudication of any dispute hereunder or in connection
herewith or with any transaction contemplated hereby or discussed herein, and
hereby irrevocably waives, and agrees not to assert in any suit action or
proceeding, any claim that it is not personally subject to the jurisdiction of
any such court, that such suit, action or proceeding is brought in an
inconvenient forum or that the venue of such suit, action or proceeding is
improper. Each party hereby irrevocably waives personal service of process and
consents to process being served in any such suit, action or proceeding by
mailing a copy thereof to such party at the address in effect for notices to it
under this Agreement and agrees that such service shall constitute good and
sufficient service of process and notice thereof. Nothing contained herein shall
be deemed to limit in any way any right to serve process in any manner permitted
by law.

         7.5 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, each of which shall be deemed an original, and all of which
together shall constitute one and the same instrument.

         7.6 HEADINGS. The headings used in this Agreement are used for
convenience only and are not to be considered in construing or interpreting this
Agreement.
