                               AGREEMENT AND PLAN
                          OF MERGER AND REORGANIZATION

      THIS AGREEMENT AND PLAN OF MERGER AND REORGANIZATION ("Agreement") is made
and entered into as of December 3, 2004, by and among: GRAPHON CORPORATION, a
Delaware corporation ("Parent"); GRAPHON VIA SUB III INC., a Delaware
corporation and a wholly owned subsidiary of Parent ("Merger Sub I"); GRAPHON
NES SUB, LLC, a California limited liability company and a wholly owned
subsidiary of Parent ("Merger Sub II" and, together with Merger Sub II, "Merger
Subs"); RALPH WESINGER ("Wesinger"); and NETWORK ENGINEERING SOFTWARE, INC., a
California corporation (the "Company"). Certain other capitalized terms used in
this Agreement are defined in Exhibit A.

                                    RECITALS

      A.   Upon the terms and subject to the conditions of this Agreement,
Parent, Merger Subs and the Company intend to effect (i) a merger of Merger Sub
I with and into the Company ("Merger I") in accordance with the California
General Corporation Law (the "CGCL") and the Delaware General Corporation Law
(the "DGCL"), and (ii) following the effectiveness of Merger I, a merger of the
Company with and into Merger Sub II in accordance with the CGCL and the
California Beverly-Killea Limited Liability Company Act (the "LLC Act") ("Merger
II," and together with Merger I, the "Transaction"). Upon consummation of the
Transaction, the Company will cease to exist.

      B.   Parent, Merger Subs and the Company intend that Merger I and Merger
II shall be treated as an integrated transaction and that the Transaction shall
qualify as a tax-free reorganization within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended (the "Code").

      C.   This Agreement has been approved by the respective boards of
directors of Parent, Merger Sub I and the Company and by the sole Member of
Merger Sub II. The board of directors of the Company has approved and determined
to recommend that the shareholders of the Company adopt this Agreement and
approve Merger I.

      D.   On July 28, 2004, a shareholder of the Company, Crystal Bay Capital,
LLC ("CBC"), the managing member of which is Nick Sprinkel ("Sprinkel," and
together with CBC, the "CBC Parties"), filed a complaint in Superior Court in
the County of Santa Clara, California, case number 104-CV-024028 (as amended,
the "CBC Action") against the Company, Wesinger and Richard Berhorst, a director
of the Company ("Berhorst"). On September 6, 2004, a default was entered against
Wesinger in connection with the CBC Action.

      E.   Contemporaneously with the execution and delivery of this Agreement,
(i) Parent, CBC and the Company are executing a Settlement Agreement and Release
(the "CBC Release") relating to the CBC Action, which, following execution, will
be placed in escrow and be delivered and become effective upon the Closing (as
defined in Section 1.3) and (ii) Parent is entering into voting agreements with
each of CBC and Wesinger (the "Voting Agreements").


                                       1.


                                    AGREEMENT

      The parties to this Agreement, intending to be legally bound, agree as
follows:

SECTION 1. DESCRIPTION OF TRANSACTION

  1.1  The Transaction. At the Effective Time of Merger I (as defined in Section
1.3), and upon the terms and subject to the conditions set forth in this
Agreement, Merger Sub I shall be merged with and into the Company, and the
separate existence of Merger Sub I shall cease. The Company shall continue as
the surviving corporation in Merger I ("Surviving Entity I"). Following the
Effective Time of Merger I, upon the terms and subject to the conditions set
forth in this Agreement and in accordance with the CGCL and the LLC Act,
Surviving Entity I will be merged with and into Merger Sub II, and the separate
existence of Surviving Entity I shall cease. Merger Sub II shall continue as the
surviving entity in Merger II (the "Surviving Entity") and shall succeed to and
assume all the rights and obligations of the Company or Surviving Entity I in
accordance with the CGCL and the LLC Act.

  1.2  Effect of the Merger. The Merger shall have the effects set forth in this
Agreement and in the applicable provisions of the CGCL and the LLC Act.

  1.3 Closing. The consummation of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Cooley Godward LLP,
One Maritime Plaza, 20th Floor, San Francisco, California 94111, at 10:00 a.m.
on a date to be designated by Parent, which shall be no later than 15 days after
the satisfaction or waiver of the last to be satisfied or waived of the
conditions set forth in Section 6 (other than the condition set forth in Section
6.2, satisfaction of which cannot be determined until the Closing) and Sections
7.1 and 7.4 (the "Scheduled Closing Time"). (The date on which the Closing
actually takes place is referred to in this Agreement as the "Closing Date.")
If, at the Scheduled Closing Time, any condition set forth in Section 6 or 7 has
not been satisfied or waived. Parent shall have the right, in its sole
discretion, to extend and delay the Scheduled Closing Time by up to 15 days.
Subject to the provisions of this Agreement, an Agreement of Merger for Merger
I, satisfying the applicable requirements of the CGCL (the "Agreement of
Merger"), shall be duly executed by the Company and concurrently with or as soon
as practicable following the Closing filed with the Secretary of State of the
State of California in accordance with the relevant provisions of the CGCL and a
Certificate of Merger for Merger I, satisfying the applicable requirements of
the DGCL, shall be duly executed by the Company and concurrently with or as soon
as practicable following the Closing filed with the Secretary of State of
Delaware in accordance with the relevant provisions of the DGCL (the time of
such filings with the Secretary of State of the State of California and the
Secretary of State of the State of Delaware (or such later time as may be agreed
in writing by the parties and specified in the Agreement of Merger) being the
"Effective Time of Merger I"). Subject to the provisions of this Agreement, a
Certificate of Merger for Merger II, satisfying the applicable requirements of
the LLC Act (the "Second Certificate of Merger"), shall be duly executed by
Merger Sub II and, following the Effective Time of Merger I, filed with the
Secretary of State of the State of Delaware in accordance with the relevant
provisions of the DGCL and the LLC Act (the time of such filing with the
Secretary of State of the State of Delaware (or such later time as may be agreed
in writing by the parties and specified in the Second Certificate of Merger)
being the "Effective Time of Merger II").

                                       2


  1.4  Articles of Incorporation;  Bylaws; Articles of Organization; Limited
Liability  Company  Operating  Agreement;   Directors  and Officers.

      (a) The directors of Surviving Entity I immediately after the Effective
Time of Merger I shall be the respective individuals who are directors of Merger
Sub I immediately prior to the Effective Time of Merger I. The officers of
Surviving Entity I immediately after the Effective Time of Merger I shall be
the individuals set forth on Exhibit B.

      (b) The Operating Agreement of the Surviving Entity immediately after the
Effective Time of Merger II shall be the Operating Agreement of Merger Sub II
immediately prior to the Effective Time of Merger II.

      (c) The officers of the Surviving Entity immediately after the Effective
Time of Merger II shall be the respective individuals who are officers of
Surviving Entity I immediately prior to the Effective Time of Merger II. The
Manager of the Surviving Entity after the Effective Time of Merger II shall be
the individual who is the Manager of Merger Sub II immediately prior to the
Effective Time of Merger II.

  1.5  Conversion of Shares.

       (a) Subject to Sections 1.8(c) and 1.9, at the Effective Time of Merger
I, by virtue of Merger I and without any further action on the part of Parent,
Merger Sub I, the Company or any shareholder of the Company:

           (i) each share of Company Common Stock outstanding immediately prior
to the Effective Time shall be converted into a number of shares of the common
stock, par value $0.0001 per share, of Parent (the "Parent Common Stock") equal
to the Per Share Exchange Ratio (as defined in Section 1.5(c)); and

           (ii) each share of the common stock (with no par value) of Merger Sub
I outstanding immediately prior to the Effective Time of Merger I shall be
converted into one share of common stock of Surviving Entity I.

      (b) If any shares of Company Common Stock outstanding immediately prior to
the Effective Time of Merger I are unvested or are subject to a repurchase
option, risk of forfeiture or other condition under any applicable restricted
stock purchase agreement or other agreement with the Company, then the shares of
Parent Common Stock issued in exchange for such shares of Company Common Stock
will also be unvested and subject to the same repurchase option, risk of
forfeiture or other condition, and the certificates representing such shares of
Parent Common Stock may accordingly be marked with appropriate legends.

      (c) The Per Share Exchange Ratio is the quotient obtained by dividing the
Net Share Consideration by 80,142. For purposes of this calculation:

           (i) "Net Share Consideration" is equal to Gross Share Consideration
less the Expense Shares and less the Sierra Shares.

           (ii) "Gross Share Consideration" is equal to 10,000,000 shares of
Parent Common Stock;

                                       3


           (iii) "Expense Shares" is equal to the quotient obtained by dividing
the Aggregate Company Expense and Liability Amount by $0.27;

           (iv) The "Aggregate Company Expense and Liability Amount" is the
aggregate dollar value of the Excess Liability Amount (as defined below) and all
Transaction-Related Expenses (as defined in Section 10.2) incurred by the
Company relating to services performed before the Closing Date. In order to
calculate the aggregate dollar value of all Transaction-Related Expenses, the
Company shall include an estimate of the Aggregate Company Expense Amount in the
Information Statement and provide to Parent, no later than one business day
prior to the Scheduled Closing Date, a written accounting of all Company
expenses included in the Aggregate Company Expense and Liability Amount,
together with appropriate supporting documentation of such expenses and a good
faith estimate of expenses to be incurred from the date of such accounting until
the Closing Date (the "Aggregate Company Expense Amount Notice").

             (A) To the extent the Company incurs additional Transaction-Related
Expenses relating to services performed on or after the Closing Date (the
"Additional Company Expenses"), Parent is expressly authorized to treat the
aggregate value of such Additional Company Expenses as Damages for which Parent
shall be indemnified pursuant to the terms of Section 9.

             (B) To the extent that, after the Closing, Parent or the Company
owes any Transaction-Related Expenses of the Company relating to services
performed before the Closing Date and that were not accounted for in the
Aggregate Company Expense Amount Notice, Parent is expressly authorized to treat
an amount equal to two times the aggregate value of such unpaid
Transaction-Related Expenses as Damages for which Parent shall be indemnified
pursuant to the terms of Section 9.

           (v) "Excess Liability Amount" is equal to the aggregate value of all
amounts owed by NES, and all amounts paid by or on behalf of NES before the
Closing, that relate to (A) any Legal Proceeding to which NES is a party, (B)
any judgment entered against NES or under which NES has any liability and (C)
any claim against the Company by, or contractual liability of the Company to,
any third party that would be reflected on a balance sheet prepared in
accordance with GAAP but that is not reflected on the Company's balance sheet as
of October 31, 2004 that is included in the Company Financial Statements (as
defined in Section 2.4); provided, however, that up to $300,000 in the aggregate
relating to the following enumerated items shall be excluded from the Excess
Liability Amount: (1) amounts paid or owed to Cardinal pursuant to the Cardinal
Agreement; (2) amounts paid or owed to Sierra (as defined in Section 1.10) with
respect to fees and expenses accrued by Sierra prior to the Closing; (3) amounts
owed that relate to the judgment lien evidenced by UCC Filing #199828660431, on
which "M. Snow" is listed as the Secured Party; (4) amounts owed that relate to
the judgment lien evidenced by UCC Filing #200126860629, on which "Heritage
Communications of St. Louis" is listed as the Secured Party; (5) amounts paid or
owed to Golf U.S.A. (as defined in Section 6.7(d)) under the Golf U.S.A.
Agreement (as defined in Section 6.7(d)); and (6) up to $25,000 owed to Bruce
Horton ("Horton") in repayment of the outstanding principal balance on a
promissory note issued to Mr. Horton in 1997 (the "Horton Note").

                                       4


           (vi) "Sierra Shares" is equal to 1,750,000 shares of Parent Common
Stock, issued to Sierra (subject to the terms of Section 1.8) at the Effective
Time of Merger I pursuant to the Sierra Agreement.

  1.6 Company Stock Options. Parent will not assume any stock options or other
securities representing the right to acquire shares of the Company's capital
stock, whether vested or unvested, in connection with Merger I.

  1.7 Closing of the Company's Transfer Books. At the Effective Time of Merger
I, holders of certificates representing shares of the Company's Common Stock
that were outstanding immediately prior to the Effective Time of Merger I (the
"Holders") shall cease to have any rights as shareholders of the Company, and
the stock transfer books of the Company shall be closed with respect to all
shares of such capital stock outstanding immediately prior to the Effective Time
of Merger I. No further transfer of any such shares of the Company's capital
stock shall be made on such stock transfer books after the Effective Time of
Merger I. If, after the Effective Time of Merger I, a valid certificate
previously representing any of such shares of the Company's capital stock (a
"Company Stock Certificate") is presented to Surviving Entity I or to the
Surviving Entity or Parent, such Company Stock Certificate shall be canceled and
shall be exchanged as provided in Section 1.8. Except as otherwise set forth in
this Agreement, Sierra shall be included in the definition of "Holders" and
shall be treated as a "Holder" for all purposes under this Agreement.

  1.8   Exchange  of  Certificates;  Cardinal  Shares;  Deposit  into Escrow.

      (a) As soon as practicable after the Effective Time of Merger I, Parent
will send to the Holders (other than Sierra) (i) a letter of transmittal in
customary form and containing such provisions as Parent may reasonably specify
and (ii) instructions for use in effecting the surrender of Company Stock
Certificates in exchange for certificates representing Parent Common Stock. Upon
surrender of a Company Stock Certificate to Parent for exchange, together with a
duly executed letter of transmittal and such other documents as may be
reasonably required by Parent, such Holder shall be entitled to receive in
exchange therefor a certificate representing the number of whole shares of
Parent Common Stock that such Holder has the right to receive pursuant to the
provisions of this Section 1, and the Company Stock Certificate so surrendered
shall be canceled. Until surrendered as contemplated by this Section 1.8, each
Company Stock Certificate shall be deemed, from and after the Effective Time of
Merger I, to represent only the right to receive upon such surrender a
certificate representing shares of Parent Common Stock (and cash in lieu of any
fractional share of Parent Common Stock) as contemplated by this Section 1. If
any Company Stock Certificate has been lost, stolen or destroyed, Parent may, in
its discretion and as a condition precedent to the issuance of any certificate
representing Parent Common Stock, require the owner of such lost, stolen or
destroyed Company Stock Certificate to provide an appropriate affidavit and to
deliver a bond (in such sum as Parent may reasonably direct) as indemnity
against any claim that may be made against Parent, Surviving Entity I or the
Surviving Entity with respect to such Company Stock Certificate.

                                       5


      (b) At or as soon as practicable after the Effective Time of Merger I, and
subject to and in accordance with the provisions of Section 9.3, Parent, on
behalf of the Holders, shall take, or cause to be taken, the following actions:

           (i) Parent shall withhold from, and not deliver to, the Holders, (A)
certificates representing 1,237,500 shares of Parent Common Stock out of the Net
Share Consideration, representing a pro rata reduction from the number of shares
of Parent Common Stock that each Holder (other than Sierra) would have otherwise
received; and (B) a certificate representing 262,500 Sierra Shares, withheld
from, and not delivered to, Sierra (the 1,500,000 total shares referenced in
this Section 1l.8(b)(i) being referred to as the "Escrow Amount");

           (ii) From the Escrow Amount, Parent shall cause to be delivered to
Cardinal, in accordance with the terms of the Cardinal Agreement (as defined in
Section 6.7(c)), a certificate representing 500,000 shares of Parent Common
Stock;

           (iii) Parent shall cause to be delivered to the Escrow Agent (as
defined in Section 9.3) certificates representing the remaining 1,000,000 shares
of the Escrow Amount (the "Deposited Shares") which shall be registered in the
name of the Escrow Agent as nominee for the Holders that surrendered their
Company Stock Certificates pursuant to the terms of this Section 1.8. The
Deposited Shares shall be beneficially owned by such Holders, shall be held in
escrow and shall be available to settle certain contingencies as provided in the
Escrow Agreement. To the extent not used for such purpose, such shares shall be
released as provided in the Escrow Agreement; and

           (iv) Parent shall withhold from, and not deliver to Wesinger,
certificates representing an additional 1,000,000 shares of Parent Common Stock
out of the Net Share consideration, representing a reduction of 1,000,000 shares
from the number of shares of Parent Common Stock that Wesinger would have
otherwise been entitled to receive (the "Wesinger Escrow Shares"), which shall
be registered in the name of the Escrow Agent as nominee for Wesinger. Such
shares shall be beneficially owned by Wesinger, shall be held in escrow and
shall be available, following recourse to all of the Escrow Amount, to settle
certain contingencies as provided in the Escrow Agreement. To the extent not
used for such a purpose, such shares shall be released as provided in the Escrow
Agreement.

      (c) No dividends or other distributions declared or made with respect to
Parent Common Stock with a record date after the Effective Time of Merger I
shall be paid to a Holder holding an unsurrendered Company Stock Certificate
with respect to the shares of Parent Common Stock represented thereby, and no
cash payment in lieu of any fractional share shall be paid to any such Holder,
until such Holder surrenders such Company Stock Certificate in accordance with
this Section 1.8 (at which time such Holder shall be entitled to receive all
such dividends and distributions and such cash payment).

      (d) No fractional shares of Parent Common Stock shall be issued in
connection with Merger I, and no certificates for any such fractional shares
shall be issued. In lieu of such fractional shares, any Holder who would
otherwise be entitled to receive a fraction of a share of Parent Common Stock
(after aggregating all fractional shares of Parent Common Stock issuable to such
Holder) shall, upon surrender of such Holder's Company Stock Certificate(s), be
paid in cash the dollar amount (rounded to the nearest whole cent), without


                                       6


interest, determined by multiplying such fraction by the closing price of the
Parent's Common Stock on the OTC-BB on the Closing Date (the "Parent Stock

Shareholders' Representative (as defined in Section 2.2 of the Holder Agreement)
a written notice alleging the existence of an inaccuracy in or a breach of any
of the representations and warranties made by the Company (and setting forth in
reasonable detail the basis for such Indemnitee's belief that such an inaccuracy
or breach may exist) and asserting a claim for recovery under Section 9.2 based
on such alleged inaccuracy or breach, then the claim asserted in such notice
shall survive the Initial Termination Date (or, with respect to the
representations and warranties contained in Section 2.14, the Extended
Termination Date) until such time as such claim is fully and finally resolved.
All representations and warranties made by Parent and Merger Subs shall
terminate and expire as of the Effective Time of Merger I, and any liability of
Parent or Merger Subs with respect to such representations and warranties shall
thereupon cease.

shall not be limited or otherwise affected by or as a result of any information
furnished to, or any investigation made by or knowledge of, any of the
Indemnitees or any of their Representatives.

      (c) For purposes of this Agreement, each statement or other item of
information set forth in the Disclosure Schedule or in any update to the
Disclosure Schedule shall be deemed to be a representation and warranty made by
the Company in this Agreement.

                                       34


  9.2  Indemnification.

      (a) From and after the Effective Time of Merger I (but subject to Section
9.1(a)), the Holders shall hold harmless and indemnify each of the Indemnitees
from and against, and shall compensate and reimburse each of the Indemnitees
for, any Damages that are directly or indirectly suffered or incurred by any of
the Indemnitees or to which any of the Indemnitees may otherwise become subject
(regardless of whether or not such Damages relate to any third-party claim) and
that arise from or as a result of, or are directly or indirectly connected with:
(i) any inaccuracy in or breach of any representation or warranty set forth in
Section 2 as of the date of this Agreement (without giving effect to any
"Material Adverse Effect" or other materiality qualification or any similar
qualification contained or incorporated directly or indirectly in such
representation or warranty, and without giving effect to any update to the
Disclosure Schedule); (ii) any inaccuracy in or breach of any representation or
warranty set forth in Section 2 as if such representation and warranty had been
made on and as of the Closing Date (without giving effect to any "Material
Adverse Effect" or other materiality qualification or any similar qualification
contained or incorporated directly or indirectly in such representation or
warranty, and without giving effect to any update to the Disclosure Schedule);
(iii) any breach of or failure to comply with any covenant, obligation or other
agreement of the Company (including the covenants set forth in the Shareholders
Agreement); (iv) any Legal Proceeding relating to any inaccuracy or breach of
the type referred to in clause "(i)," "(ii)" or "(iii)" above (including any
Legal Proceeding commenced by any Indemnitee for the purpose of enforcing any of
its rights under this Section 9).

      (b) If Surviving Entity I or the Surviving Entity suffers, incurs or
otherwise becomes subject to any Damages as a result of or in connection with
any inaccuracy in or breach of any representation, warranty, covenant or
obligation, then (without limiting any of the rights of Surviving Entity I or
the Surviving Entity as an Indemnitee) Parent shall also be deemed, by virtue of
its ownership of the stock of Surviving Entity I and the Surviving Entity, to
have incurred Damages as a result of and in connection with such inaccuracy or
breach.

      (c) No Holder's indemnification obligation to any Indemnitee under this
Section 9.2 shall exceed such Holder's share of the Escrow Amount; provided,
however, that Wesinger's indemnification obligation shall be unlimited with
respect to inaccuracies in the representations and warranties set forth in
Sections 2.1, 2.3, 2.20 and 2.21 (and Parent need not exhaust the security of
the Escrow Amount prior to seeking indemnification directly from Wesinger); and,
provided further, that Wesinger's indemnification obligation for all other
purposes shall be limited to Wesinger's share of the Deposited Shares plus the
entirety of the Wesinger Escrow Shares.

  9.3 Escrow Fund. Each Holder receiving Parent Common Stock in Merger I will be
deemed to have received and deposited with the Escrow Agent (as defined below)
the Deposited Shares (plus any additional shares as may be issued upon any stock
split, stock dividend or recapitalization effected by Company after the
Effective Time of Merger I with respect to the Escrow Amount). The Deposited
Shares, together with the Wesinger Escrow Shares, will be deposited with and
will be held by an institution mutually acceptable to Company and the
Shareholders' Representatives as Escrow Agent (the "Escrow Agent"), such deposit
to constitute an escrow fund to be governed by the terms set forth in the Escrow
Agreement. Payment of any amounts from the Deposited Shares shall be taken from
the Escrow Shares as set forth in the Escrow Agreement.

                                ESCROW AGREEMENT

      THIS ESCROW AGREEMENT is made and entered into as of December __, 2004, by
and among: GRAPHON CORPORATION, a Delaware corporation ("GraphOn"); RALPH
WESINGER, as representative (the "Shareholders' Representative") of the
shareholders of NETWORK ENGINEERING SOFTWARE, INC., a California corporation
("NES"), identified on Schedule A (the "Merger Shareholders"); and AMERICAN
STOCK TRANSFER AND TRUST COMPANY, a New York corporation (the "Escrow Agent").


                                    RECITALS

      A. Pursuant to an Agreement and Plan of Merger and Reorganization dated as
of December 3, 2004, among GraphOn, GraphOn via Sub III Inc., a Delaware
corporation and a wholly owned subsidiary of GraphOn ("Merger Sub"), GraphOn NES
Sub, LLC, a California limited liability company and a wholly owned subsidiary
of GraphOn ("Merger Sub II"), Network Engineering Software, Inc., a California
corporation ("NES"), and Ralph Wesinger (the "Reorganization Agreement"), it is
contemplated that (i) Merger Sub will merge with and into NES (the merger of
Merger Sub with and into NES being referred to in this Holder Agreement as the
"Merger") with NES being the surviving corporation in the Merger, (ii) following
the Merger, NES will merge with and into Merger Sub II and (iii) NES's
stockholders will receive shares of common stock, $0.0001 par value per share,
of GraphOn ("GraphOn Common Stock") in exchange for their shares of common stock
of NES ("NES Common Stock").

      B. The Reorganization Agreement contemplates the establishment of an
escrow arrangement to secure rights to indemnification, compensation and
reimbursement of GraphOn and the other Indemnitees under the Reorganization
Agreement.

      C. Pursuant to Section 9.3 of the Reorganization Agreement, Section 2.2 of
the Holder Agreement and Section 10 of this Escrow Agreement, the Shareholders'
Representative has been irrevocably appointed to serve for, among other things,
administration of the provisions of Section 9.2 and Section 9.3 of the
Reorganization Agreement and Section 2.2 of the Holder Agreement.

      D. Capitalized terms used but not defined herein are defined in the
Reorganization Agreement.

                                    AGREEMENT

      The parties, intending to be legally bound, agree as follows:

      Section 1. Defined Terms.

  1.1 As used in this Escrow Agreement, the term "Merger Shareholders" shall
refer initially to Sierra and all Persons who were shareholders of NES
immediately prior to the Effective Time ("NES Shareholders") and who prior to
the Effective Time either (a) voted in favor of or consented in writing to the
adoption of the Reorganization Agreement or (b) failed to take any action
required by Section 1300 of the California General Corporation Law (the


                                       1


"California Law") to have been taken prior to such time in order to perfect or
otherwise preserve their dissenters' rights thereunder. In the event that
following the Effective Time, any NES Shareholder who was not initially a Merger
Shareholder either (i) votes in favor of or consents in writing to the adoption
of the Reorganization Agreement or (ii) otherwise takes (or omits to take) any
action that results in the failure of such NES Shareholder to perfect or
preserve his dissenters' rights under Section 1300 of the California Law, such
NES Shareholder shall automatically and without the requirement of any action on
the part of such NES Shareholder or any party to this Escrow Agreement be deemed
to be a Merger Shareholder hereunder. GraphOn shall cause Schedule A to be
revised from time to time to reflect any such additional Merger Shareholders.

      Section 2. Escrow and Indemnification.

  2.1 Shares and Stock Powers Placed in Escrow. At or following the Effective
Time, in accordance with the Reorganization Agreement, (a) GraphOn shall issue
certificates for shares of GraphOn Common Stock registered in the names of each
of the Merger Shareholders, evidencing the shares of GraphOn Common Stock to be
held in escrow on behalf of the Merger Shareholders as set forth on Schedule A,
in accordance with this Escrow Agreement, and (b) each of the Merger
Shareholders shall deliver to GraphOn five "assignments separate from
certificate" ("Stock Powers") endorsed by each such Merger Shareholder in blank.
The shares of GraphOn Common Stock being held in escrow pursuant to this Escrow
Agreement (the "Escrow Shares"), including the Deposited Shares and the Wesinger
Escrow Shares, shall collectively constitute an escrow fund (the "Escrow Fund")
with respect to the indemnification, compensation and reimbursement rights of
GraphOn and the other Indemnitees under the Reorganization Agreement. The Escrow
Agent agrees to accept delivery of the Escrow Fund and to hold the Escrow Fund
in an escrow account (the "Escrow Account"), subject to the terms and conditions
of this Escrow Agreement.

  2.2 Voting of Escrow Shares. The record owner of the Escrow Shares shall be
entitled to exercise all voting rights with respect to such Escrow Shares. The
Escrow Agent is not obligated to distribute to the Merger Shareholders or to the
Shareholders' Representative proxy materials and other documents relating to the
Escrow Shares received by the Escrow Agent from GraphOn.

  2.3 Security Interest. To the extent and so long as Escrow Shares are held in
the Escrow Account hereunder, GraphOn shall have, and the Merger Shareholders
(through the Shareholders' Representative) hereby grant, as of and from the date
of this Escrow Agreement, a perfected, first-priority security interest in such
Escrow Shares to secure payment of amounts, if any, payable to GraphOn and other
Indemnitees in respect of Section 9 of the Reorganization Agreement. In
connection therewith, each Merger Shareholder (through the Shareholders'
Representative) expressly agrees (i) that the Escrow Agent is acting solely as
GraphOn's agent to the extent necessary to perfect GraphOn's first-priority
security interest in the Escrow Shares, and (ii) to execute and deliver such
instruments as GraphOn may from time to time reasonably request for the purpose
of evidencing and perfecting such security interest.

  2.4 Dividends, Etc. GraphOn and the Shareholders' Representative (on behalf of
each of the Merger Shareholders) agree among themselves, for the benefit of
GraphOn and the Escrow Agent, that any shares of GraphOn Stock or other property
(other than ordinary cash dividends) distributable or issuable (whether by way


                                       2


of dividend, stock split or otherwise) in respect of or in exchange for any
Escrow Shares (including pursuant to or as a part of a merger, consolidation,
acquisition of property or stock, reorganization or liquidation involving
GraphOn) shall not be distributed or issued to the beneficial owners of such
Escrow Shares, but rather shall be distributed or issued to and held by the
Escrow Agent in the Escrow Account as part of the Escrow Fund. Ordinary cash
dividends payable in respect of the Escrow Shares will be paid by GraphOn
directly to the applicable Merger Shareholders and not to the Escrow Agent. Any
securities or other property received by the Escrow Agent in respect of any
Escrow Shares held in escrow as a result of any stock split or combination of
shares of GraphOn Common Stock, payment of a stock dividend or other stock
distribution in or on shares of GraphOn Common Stock, or change of GraphOn
Common Stock into any other securities pursuant to or as a part of a merger,
consolidation, acquisition of property or stock, reorganization or liquidation
involving GraphOn, or otherwise, shall be held by the Escrow Agent as, and shall
be included within the definition of, Escrow Shares.

  2.5 Transferability. The interests of the Merger Shareholders in the Escrow
Account and in the Escrow Shares shall not be assignable or transferable, other
than by operation of law. No assignment or transfer of any of such interests by
operation of law shall be recognized or given effect until GraphOn and the
Escrow Agent shall have received written notice of such assignment or transfer.

  2.6 Fractional Shares. No fractional shares of GraphOn Common Stock or other
securities shall be retained in or released from the Escrow Account pursuant to
this Escrow Agreement. In connection with any release of Escrow Shares from the
Escrow Account, GraphOn and the Escrow Agent shall be permitted to "round down"
or to follow such other rounding procedures as GraphOn reasonably determines to
be appropriate in order to avoid retaining any fractional shares in the Escrow
Account and in order to avoid releasing any fractional shares from the Escrow
Account.

  2.7 Trust Fund. The Escrow Fund shall be held as a trust fund and shall not be
subject to any lien, attachment, trustee process or any other judicial process
of any creditor of any Merger Shareholder or of any party hereto. The Escrow
Agent shall hold and safeguard the Escrow Fund until any remaining Escrow Shares
are distributed at the Initial Termination Date or the Extended Termination
Date, as applicable, provided that if the Escrow Agent has received from any
Indemnitee a Claim Notice setting forth a claim that has not been resolved by
the Initial Termination Date or the Extended Termination Date, as applicable,
then the Escrow Agent shall hold and safeguard all or a portion of the Escrow
Fund, as set forth in greater detail in Section 4.1, until the claim has been
resolved and the Escrow Fund released in accordance with this Escrow Agreement.

      Section 3. Administration of Escrow Account. Except as otherwise provided
herein, the Escrow Agent shall administer the Escrow Account as follows:

  3.1 If any Indemnitee has or claims to have incurred or suffered Damages for
which it is or may be entitled to indemnification, compensation or reimbursement
under Section 9 of the Reorganization Agreement, such Indemnitee may, on or
prior to (a) the Initial Termination Date, with respect to all claims other than
Extended Period Claims, and (b) the Extended Termination Date, with respect to
Extended Period Claims deliver a claim notice (a "Claim Notice") to the


                                       3


Shareholders' Representative and to the Escrow Agent. Each Claim Notice shall
state that such Indemnitee believes that there is or has been a breach of a
representation, warranty or covenant contained in the Reorganization Agreement
or that such Indemnitee is otherwise entitled to indemnification, compensation
or reimbursement under Section 9 of the Reorganization Agreement, and contain a
brief description of the circumstances supporting such Indemnitee's belief that
there is or has been such a breach or that such Indemnitee is so entitled to
indemnification, compensation or reimbursement and shall, to the extent
possible, contain a good faith, non-binding, preliminary estimate of the amount
of Damages such Indemnitee claims to have so incurred or suffered (the "Claimed
Amount").

  3.2 Within 30 days after receipt by the Shareholders' Representative of a
Claim Notice, the Shareholders' Representative may deliver, both to the
Indemnitee who delivered the Claim Notice and to the Escrow Agent, a written
response (the "Response Notice") in which the Shareholders' Representative: (i)
agrees that Escrow Shares (or cash, as described further in Section 5)
collectively having a "Stipulated Value" (as defined below) equal to the full
Claimed Amount (the "Full Amount") may be released from the Escrow Account to
the Indemnitee; (ii) agrees that Escrow Shares (or cash, as described further in
Section 5) collectively having a Stipulated Value equal to part, but not all, of
the Claimed Amount (the "Agreed Amount") may be released from the Escrow Account
to the Indemnitee; or (iii) indicate that no part of the Escrow Fund may be
released from the Escrow Account to the Indemnitee in respect of the Claimed
Amount. Any part of the Claimed Amount that is not agreed to be released to the
Indemnitee pursuant to the Response Notice shall be the "Contested Amount." If a
Response Notice is not received by the Escrow Agent within such 30-day period,
then the Shareholders' Representative shall be conclusively deemed to have
agreed that Escrow Shares (or cash, as described further in Section 5)
collectively having a Stipulated Value equal to the Full Amount may be released
to the Indemnitee from the Escrow Account.

  3.3 If the Shareholders' Representative delivers a Response Notice agreeing
that Escrow Shares (or cash, as described further in Section 5) collectively
having a Stipulated Value equal to the full Claimed Amount may be released from
the Escrow Account to the Indemnitee, or if the Shareholders' Representative
does not deliver a Response Notice on a timely basis in accordance with Section
3.2, the Escrow Agent shall within five business days following the receipt of
such Response Notice (or, if the Escrow Agent has not received a Response
Notice, within five business days following the expiration of the 30-day period
referred to in Section 3.2), deliver to such Indemnitee such Escrow Shares (or
cash, as described further in Section 5).

  3.4 If the Shareholders' Representative delivers a Response Notice agreeing
that Escrow Shares (or cash, as described further in Section 5) collectively
having a Stipulated Value equal to less than the Full Amount may be released
from the Escrow Account to the Indemnitee, the Escrow Agent shall, within five
business days following the receipt of such Response Notice, deliver to such
Indemnitee Escrow Shares (or cash, as described further in Section 5)
collectively having a Stipulated Value equal to the Agreed Amount. Such payment
shall not be deemed to be made in full satisfaction of the claim described in
such Claim Notice, but shall count toward the satisfaction of the claim
described in such Claim Notice.

  3.5 If the Shareholders' Representative delivers a Response Notice indicating
that there is a Contested Amount, the Shareholders' Representative and the
Indemnitee shall attempt in good faith to resolve the dispute related to the


                                       4


Contested Amount. If the Indemnitee and the Shareholders' Representative
resolves such dispute, such resolution shall be binding on all of the Merger
Shareholders and such Indemnitee and a settlement agreement shall be signed by
such Indemnitee and the Shareholders' Representative and sent to the Escrow
Agent, which shall, upon receipt thereof, if applicable, release Escrow Shares
(or cash, as described further in Section 5) collectively having a Stipulated
Value equal to the additional amount as listed in the settlement agreement (the
"Settlement Amount"). Unless and until the Escrow Agent shall receive written
notice that any such dispute has been resolved by the Indemnitee and the
Shareholders' Representative, the Escrow Agent may assume without inquiry that
such dispute has not been resolved.

  3.6 If the Shareholders' Representative and the Indemnitee are unable to
resolve the dispute relating to any Contested Amount within 60 days after the
delivery of the Claim Notice ("Initial Resolution Period"), then the claim
described in the Claim Notice shall be settled by binding arbitration in the
County of Santa Clara in the State of California in accordance with the
Commercial Arbitration Rules then in effect of the American Arbitration
Association (the "AAA Rules"). Arbitration will be conducted by one arbitrator,
mutually selected by GraphOn and the Shareholders' Representative. If GraphOn
and the Shareholders' Representative fail to mutually select an arbitrator
within three business days following the expiration of the Initial Resolution
Period, then arbitration will be conducted by three arbitrators: one selected by
GraphOn; one selected by the Shareholders' Representative; and the third
selected by the first two arbitrators. If GraphOn or the Shareholders'
Representative fails to select an arbitrator within 10 days following the
expiration of the Initial Resolution Period, then the other shall be entitled to
select the second arbitrator. The parties agree to use all reasonable efforts to
cause the arbitration hearing to be conducted within 75 days after the
appointment of the mutually-selected arbitrator or the last of the three
arbitrators, as the case may be, and to use all reasonable efforts to cause the
decision of the arbitrator(s) to be furnished within 95 days after the
appointment of the mutually-selected arbitrator or the last of the three
arbitrators, as the case may be. The parties further agree that discovery shall
be completed at least 10 days prior to the date of the arbitration hearing. The
decision of the arbitrator(s) shall relate solely to: (a) whether the Indemnitee
is entitled to receive the Contested Amount (or a portion thereof), and the
portion of such Contested Amount the Indemnitee is entitled to receive; and (b)
the determination of the non-prevailing party as provided below. The final
decision of the arbitrator(s) shall be furnished to the Shareholders'
Representative, the Indemnitee and the Escrow Agent in writing and shall
constitute a conclusive determination of the issue(s) in question, binding upon
the Shareholders' Representative, the Merger Shareholders, the Indemnitee and
the Escrow Agent and shall not be contested by any of them. The non-prevailing
party in any arbitration shall pay the reasonable expenses (including attorneys'
fees) of the prevailing party, any additional reasonable fees and expenses
(including reasonable attorneys' fees) of the Escrow Agent, and the fees and
expenses associated with the arbitration (including the arbitrators' fees and
expenses). For purposes of this Section 3.6, the non-prevailing party shall be
determined solely by the arbitrator(s).  Any amounts payable by the Merger
Shareholders shall be paid out of Escrow Shares (or cash, as described further
in Section 5) pursuant to the written decision of the arbitrator(s).

  3.7 The Escrow Agent shall have delivered to it: (a) a copy of a settlement
agreement executed by the Indemnitee and the Shareholders' Representative
setting forth instructions to the Escrow Agent as to the release of Escrow
Shares (or cash, as described further in Section 5); or (b) a copy of the award
of the arbitrator(s) referred to and as provided in Section 3.6 setting forth


                                       5


instructions to the Escrow Agent as to the release of Escrow Shares (or cash, as
described further in Section 5). Within five (5) days of receipt of such
settlement agreement or arbitration award, the Escrow Agent shall release Escrow
Shares (or cash, as described further in Section 5) collectively having a
Stipulated Value equal to the additional amount as listed in the settlement
agreement or arbitration award (the "Arbitration Amount")

  3.8 Any Escrow Shares released from the Escrow Account shall be deemed to
reduce the Escrow Shares pro rata with respect to each applicable Merger
Shareholder in accordance with each Merger Shareholder's percentage interest in
the Escrow Fund as set forth on Schedule A. All Deposited Shares shall have been
released in accordance with this Section 3 before any of the Wesinger Escrow
Shares are released.

      Section 4. Release of Escrow Shares.

  4.1 Within five business days after the Initial Termination Date, the Escrow
Agent shall, upon receipt of written notice from the Shareholders'
Representative, distribute or cause to be distributed to each of the Merger
Shareholders at such Merger Shareholder's address set forth on Schedule A such
Merger Shareholder's pro-rata portion of the Deposited Shares (or other property
held in the Escrow Account), if any, then held in escrow based on the percentage
interests set forth on Schedule A and shall distribute or cause to be
distributed to Wesinger all Wesinger Escrow Shares, if any, then held in escrow
in excess of 250,000 shares; provided, however, that if prior to the Initial
Termination Date, any Indemnitee has given a Claim Notice containing a claim
that has not been resolved prior to the Initial Termination Date in accordance
with Section 3, the Escrow Agent shall retain in the Escrow Account after the
Initial Termination Date. Within five business days after the Extended
Termination Date, the Escrow Agent shall, upon receipt of written notice from
the Shareholders' Representative, distribute or cause to be distributed to
Wesinger all Wesinger Escrow Shares, if any, then held in escrow; provided,
however, that if prior to the Extended Termination Date any Indemnitee has given
a claim Notice containing an Extended Period Claim that has not been resolved
prior to the Extended Termination Date in accordance with Section 3, the Escrow
Agent shall retain in the Escrow Account after the Extended Termination Date
Escrow Shares collectively having a Stipulated Value equal to 120% of the
Claimed Amount or Contested Amount, as the case may be, with respect to all
claims that have not then been resolved. (The parties acknowledge that it is
appropriate to retain more than 100% of the Claimed Amount in the Escrow Account
in recognition of the fact that the Indemnitee may have underestimated the
aggregate amount of the actual and potential Damages arising from a particular
breach or other matter.)

  4.2 Distributions of GraphOn Common Stock shall be made to GraphOn or the
Merger Shareholders, as appropriate, at the addresses set forth on Schedule A.
Whenever a distribution is to be made to the Merger Shareholders, pro rata
distributions shall be made to each of them based on the percentage interests in
the Escrow Fund and at their addresses set forth on Schedule A.

      Section 5. Sale of Escrow Shares; Valuation of Escrow Shares, Etc.

  5.1 Required Sale of Escrow Shares to Satisfy Claims. Any time the Escrow
Agent is directed to release Escrow Shares from the Escrow Account equal to the
Full Amount, the Agreed Amount, the Settlement Amount or the Arbitration Amount,
if such Escrow Shares can be sold, using best efforts to attain the highest


                                       6


possible per share price in connection with such sale, at an average per share
price equal to or exceeding $0.338 (the "80% Threshold"), the Shareholders'
Representative shall provide written notice to the Escrow Agent to release to
the Shareholders' Representative a number of shares out of the Escrow Account,
in accordance with the priority established in Section 3.8, to be sold by the
Shareholders' Representative such that 80% of the gross proceeds from such sale
or sales equals the applicable Full Amount, Agreed Amount, Settlement Amount or
Arbitration Amount. Any shares that are not sold by the Shareholders'
Representative, and any cash proceeds from the sale of Escrow Shares that did
not need to be sold in order for 80% of the gross proceeds from such sale or
sales to equal the applicable Full Amount, shall promptly be returned to the
Escrow Account. The remaining proceeds from any such sale, net of commissions,
costs and fees relating to such sale, shall be distributed to the Merger
Shareholders (with respect to Deposited Shares sold in such sale) and to
Wesinger (with respect to Wesinger Escrow Shares sold in such sale).

  5.2 Stipulated Value. The "Stipulated Value" shall be the higher of (a) $0.27
per Escrow Share and (b) if the 80% Threshold is met or exceeded, cash equal to
the Full Amount, the Agreed Amount, the Settlement Amount or the Arbitration
Amount, as applicable.

  5.3 Stock Splits. All numbers contained in, and all calculations required to
be made pursuant to, this Escrow Agreement with respect to the Escrow Shares
shall be adjusted as appropriate to reflect any stock split, reverse stock
split, stock dividend or similar transaction effected by GraphOn after the date
hereof; provided, however, that the Escrow Agent shall have received notice of
such stock split or other action and shall have received the appropriate number
of additional shares of GraphOn Common Stock or other property pursuant to
Section 2.4. In the event of any such stock split or other similar occurrence,
GraphOn shall deliver to the Shareholders' Representative and the Escrow Agent a
revised version of Schedule A setting forth the new number of Escrow Shares held
in the Escrow Fund. Unless and until the Escrow Agent receives the certificates
representing additional shares of GraphOn Common Stock or other property
pursuant to Section 2.4, the Escrow Agent may assume without inquiry that no
such stock or other property has been or is required to be issued with respect
to Escrow Shares.

      Section 6. Fees and Expenses. The Escrow Agent shall be entitled to
receive from time to time fees in accordance with Schedule B. In accordance with
Schedule B, the Escrow Agent will also be entitled to reimbursement for
reasonable and documented out-of-pocket expenses incurred by the Escrow Agent in
the performance of its duties hereunder and the execution and delivery of this
Escrow Agreement. All such fees and expenses shall be paid by GraphOn, and any
such amounts paid by GraphOn will be Damages for which GraphOn may seek
reimbursement pursuant to the procedures set forth in this Escrow Agreement.

      Section 7. Limitation of Escrow Agent's Liability.

  7.1 The Escrow Agent undertakes to perform such duties as are specifically set
forth in this Escrow Agreement only and shall have no duty under any other
agreement or document, and no implied covenants or obligations shall be read
into this Escrow Agreement against the Escrow Agent. The Escrow Agent shall
incur no liability with respect to any action taken by it or for any inaction on
its part in reliance upon any notice, direction, instruction, consent, statement
or other document believed by it in good faith to be genuine and duly
authorized, nor for any other action or inaction except for its own negligence


                                       7


or willful misconduct. In all questions arising under this Escrow Agreement, the
Escrow Agent may rely on the advice of counsel, and for anything done, omitted
or suffered in good faith by the Escrow Agent based upon such advice the Escrow
Agent shall not be liable to anyone. In no event shall the Escrow Agent be
liable for incidental, punitive or consequential damages.

  7.2 GraphOn and the Shareholders' Representative jointly and severally hereby
agree to indemnify the Escrow Agent and its officers, directors, employees and
agents for, and hold it and them harmless against, any loss, liability or
expense incurred without negligence or willful misconduct on the part of Escrow
Agent, arising out of or in connection with the Escrow Agent carrying out its
duties hereunder. This right of indemnification, compensation and reimbursement
shall survive the termination of this Escrow Agreement, and the resignation of
the Escrow Agent.

      Section 8. Termination. This Escrow Agreement shall terminate on the
Extended Termination Date or, if earlier, upon the release by the Escrow Agent
of the entire Escrow Fund in accordance with this Escrow Agreement; provided,
however, that if the Escrow Agent has received from any Indemnitee a Claim
Notice setting forth a claim that has not been resolved by the Extended
Termination Date, then this Escrow Agreement shall continue in full force and
effect until the claim has been resolved and the Escrow Fund released in
accordance with this Escrow Agreement.

      Section 9. Successor Escrow Agent. In the event the Escrow Agent becomes
unavailable or unwilling to continue as escrow agent under this Escrow
Agreement, the Escrow Agent may resign and be discharged from its duties and
obligations hereunder by giving its written resignation to the parties to this
Escrow Agreement. Such resignation shall take effect not less than 30 days after
it is given to all parties hereto. In such event, GraphOn may appoint a
successor Escrow Agent. If GraphOn fails to appoint a successor Escrow Agent
within 15 days after receiving the Escrow Agent's written resignation, the
Escrow Agent shall have the right to apply to a court of competent jurisdiction
for the appointment of a successor Escrow Agent. The successor Escrow Agent
shall execute and deliver to the Escrow Agent an instrument accepting such
appointment, and the successor Escrow Agent shall, without further acts, be
vested with all the estates, property rights, powers and duties of the
predecessor Escrow Agent as if originally named as Escrow Agent herein. The
Escrow Agent shall act in accordance with written instructions from GraphOn as
to the transfer of the Escrow Fund to a successor escrow agent.

       Section 10.  Shareholders' Representative.

  10.1 As provided in the Reorganization Agreement and the Holder Agreement
attached as Exhibit D to the Reorganization Agreement, by virtue of the adoption
of the Reorganization Agreement and the entry into the Holder Agreement, the
Merger Shareholders shall be deemed to have approved the indemnification,
compensation, reimbursement and escrow terms set forth in the Reorganization
Agreement and this Escrow Agreement and the appointment of Ralph Wesinger as the
Shareholders' Representative, to give and receive notices and communications, to
authorize delivery to GraphOn of GraphOn Common Stock, cash or other property
from the Escrow Fund, to object to such deliveries, to agree to, negotiate,
enter into settlements and compromises of, and demand dispute resolution
pursuant to Section 3 and comply with orders of courts and awards of
arbitrator(s) with respect to claims of Indemnitees hereunder, and to take all
actions necessary or appropriate in the reasonable judgment of the Shareholders'
Representative for the accomplishment of the foregoing.

                                       8


  10.2 Unless and until GraphOn and the Escrow Agent shall have received written
notice otherwise, GraphOn and the Escrow Agent shall be entitled to rely on, and
shall be fully protected relying on, the power and authority of the
Shareholders' Representative to act on behalf of the Merger Shareholders.

      Section 11.  Miscellaneous.

  11.1 Attorneys' Fees. In any action at law or suit in equity to enforce or
interpret this Escrow Agreement or the rights of any of the parties hereunder,
the prevailing party in such action or suit shall be entitled to receive a
reasonable sum for its attorneys' fees and all other reasonable costs and
expenses incurred in such action or suit.

  11.2 Notices. Any notice or other communication required or permitted to be

given.

delivered on behalf of all of the parties hereto; provided, however, that any


                                       10


amendment executed and delivered by the Shareholders' Representative shall be
deemed to have been approved by and duly executed and delivered by all of the
Merger Shareholders.

  11.9 Severability. Any term or provision of this Escrow Agreement that is
invalid or unenforceable in any situation in any jurisdiction shall not affect
the validity or enforceability of the remaining terms and provisions hereof or
the validity or enforceability of the offending term or provision in any other
situation or in any other jurisdiction. If the final judgment of a court of
competent jurisdiction declares that any term or provision hereof is invalid or
unenforceable, the parties hereto agree that the court making such determination
shall have the power to limit the term or provision, to delete specific words or
phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision, and
this Escrow Agreement shall be enforceable as so modified. In the event such
court does not exercise the power granted to it in the prior sentence, the
parties hereto agree to replace such invalid or unenforceable term or provision
with a valid and enforceable term or provision that will achieve, to the extent
possible, the economic, business and other purposes of such invalid or
unenforceable term.

  11.10 Parties in Interest. Except as expressly provided herein, none of the

relating to the subject matter hereof and supersede all prior agreements and
understandings among or between any of the parties relating to the subject
matter hereof.

  11.12 Tax  Reporting  Information  and  Certification  of  Tax  Identification
Numbers.

        (a) The parties hereto agree that, for tax reporting purposes, all
interest on or other income, if any, attributable to the Escrow Fund or any
other amount held in escrow by the Escrow Agent pursuant to this Escrow
Agreement shall be allocable to the Merger Shareholders in accordance with their
percentage interests in the Escrow Fund set forth on Schedule A; provided,
however, that if GraphOn or NES shall have repurchased any Escrow Shares in
accordance with Section 3.8, then all interest on or other income, if any,
attributable to the Escrow Shares or any other amount held in escrow by the
Escrow Agent pursuant to this Escrow Agreement received after such repurchase
shall be allocable to the Merger Shareholders based on the number of Escrow
Shares held on behalf of each such Merger Shareholder at the time of the receipt
of such interest or other income (it being understood that, for purposes of
permitting the Escrow Agent to make such allocations, GraphOn and the
Shareholders' Representative shall jointly (i) calculate revised percentage
interests for the Merger Shareholders based on such number of Escrow Shares and
(ii) submit such calculations in writing to the Escrow Agent).

        (b) GraphOn and each of the Merger Shareholders agree to provide the
Escrow Agent with certified tax identification numbers for each of them by
furnishing appropriate forms W-9 (or Forms W-8, in the case of non-U.S. persons)
and any other forms and documents that the Escrow Agent may reasonably request
(collectively, "Tax Reporting Documentation") to the Escrow Agent within 30 days


                                       11


after the date hereof. The parties hereto understand that, if such Tax Reporting
Documentation is not so furnished to the Escrow Agent, the Escrow Agent shall be
required by the Code to withhold a portion of any interest or other income
earned on the investment of monies or other property held by the Escrow Agent
pursuant to this Escrow Agreement, and to immediately remit such withholding to
the Internal Revenue Service.

  11.13 Cooperation. The Shareholders' Representative agrees to cooperate fully
with GraphOn and the Escrow Agent and to execute and deliver such further
documents, certificates, agreements and instruments and to take such other
actions as may be reasonably requested by GraphOn or the Escrow Agent to
evidence or reflect the transactions contemplated by this Escrow Agreement and
to carry out the intent and purposes of this Escrow Agreement.

        (a) For purposes of this Escrow Agreement, whenever the context
requires: the singular number shall include the plural, and vice versa; the
masculine gender shall include the feminine and neuter genders; the feminine
gender shall include the masculine and neuter genders; and the neuter gender
shall include masculine and feminine genders.

        (b) The parties hereto agree that any rule of construction to the effect
that ambiguities are to be resolved against the drafting party shall not be
applied in the construction or interpretation of this Escrow Agreement.

        (c) As used in this Escrow Agreement, the words "include" and
"including," and variations thereof, shall not be deemed to be terms of
limitation, but rather shall be deemed to be followed by the words "without
limitation."

Agreement to "Sections" and "Schedules" are intended to refer to Sections of

      THIS HOLDER AGREEMENT is entered into as of December ___, 2004, by and
among GRAPHON CORPORATION, a Delaware corporation ("GraphOn"), and the Persons
listed on Exhibit A hereto, referred to hereinafter as the "Holders" and each
individually as a "Holder."


                                    RECITALS

  A. Pursuant to an Agreement and Plan of Merger and Reorganization dated as of
December 3, 2004, among GraphOn, GraphOn via Sub III Inc., a Delaware

Sub, LLC, a California limited liability company and a wholly owned subsidiary
of GraphOn ("Merger Sub II"), Network Engineering Software, Inc., a California
corporation ("NES"), and Ralph Wesinger (the "Reorganization Agreement"), it is
contemplated that (i) Merger Sub will merge with and into NES (the merger of
Merger Sub with and into NES being referred to in this Holder Agreement as the
"Merger") with NES being the surviving corporation in the Merger, (ii) following
the Merger, NES will merge with and into Merger Sub II and (iii) NES's
stockholders will receive shares of common stock, $0.0001 par value per share,
of GraphOn ("GraphOn Common Stock") in exchange for their shares of common stock
of NES ("NES Common Stock").

  B. GraphOn's obligations in the Reorganization Agreement are conditioned upon
the execution and delivery of this Holder Agreement by each Holder.

  C. Capitalized terms used but not defined herein are defined in the
Reorganization Agreement.

                                    AGREEMENT


      GraphOn and the Holders, intending to be legally bound, agree as follows:


Section 1. REGISTRATION RIGHTS.

  1.1  Definitions.  For the purpose of this Section 1:

      (a) the term "Registration Statement" shall mean any registration
statement required to be filed by Section 1.2 and shall include any preliminary
prospectus, final prospectus, exhibit or amendment included in or relating to
such registration statements; and

      (b) the term "Registrable Shares" shall mean all shares of GraphOn Common
Stock issued to the Holders in connection with the Merger.

  1.2  Registration Procedures and Expenses.  GraphOn shall:

      (a) use its best efforts to file a Registration Statement with the SEC
within ninety (90) days following the Closing Date to register the Registrable


                                       1


Shares on Form S-1 and Rule 415 under the Securities Act or on such other
appropriate form that GraphOn may be permitted to use to register such
Registrable Shares for resale from time to time by the Holders;

      (b) use commercially reasonable efforts, subject to receipt of necessary
information from the Holders, to cause any such Registration Statement filed
pursuant to Section 1.2(a) above to become effective as promptly after filing of
such Registration Statement as practicable;

      (c) prepare and file with the SEC such amendments and supplements to such
Registration Statement and the prospectus used in connection therewith as may be
necessary to keep such Registration Statement continuously effective until
termination of such obligation as provided in Section 1.4, subject to GraphOn's
right to suspend pursuant to Section 1.3;

      (d) furnish to each Holder who received Registrable Shares (and to each
underwriter, if any, of such Registrable Shares) such number of copies of
prospectuses in conformity with the requirements of the Securities Act and such
other documents as the Holders may reasonably request, in order to facilitate
the public sale or other disposition of all or any of the Registrable Shares by
the Holders;

      (e) file such documents as may be required of GraphOn for normal
securities law clearance for the resale of the Registrable Shares in such states
of the United States as may be reasonably requested by each Holder; provided,
however, that GraphOn shall not be required in connection with this paragraph
"(e)" to qualify as a foreign corporation or execute a general consent to
service of process in any jurisdiction; and

      (f) advise each Holder who received Registrable Shares promptly:

           (i) of the effectiveness of the Registration Statement or any
post-effective amendments thereto;

           (ii) of any request by the SEC for amendments to the Registration
Statement or amendments to the prospectus or for additional information relating
thereto;

           (iii) of the issuance by the SEC of any stop order suspending the
effectiveness of the Registration Statement under the Securities Act or of the
suspension by any state securities commission of the qualification of the
Registrable Shares for offering or sale in any jurisdiction, or the initiation
of any proceeding for any of the preceding purposes;

           (iv) of the suspension by GraphOn of the use of the prospectus
forming a part of the Registration Statement; and

           (v) of the existence of any fact and the happening of any event that
makes any statement of a material fact made in the Registration Statement, the
prospectus and amendment or supplement thereto, or any document incorporated by
reference therein, untrue, or that requires the making of any additions to or
changes in the Registration Statement or the prospectus in order to make the
statements therein not misleading; and

                                       2


      (g) use commercially reasonable efforts to cause all Registrable Shares to
be listed on each securities exchange, if any, on which equity securities of
GraphOn are then listed.

  1.3 Delay and Suspension of Prospectus. At GraphOn's reasonable discretion,
GraphOn may delay the effectiveness of, and may suspend the use of, the
prospectus forming a part of the Registration Statement, including to the extent
necessary to file any post-effective amendment to the Registration Statement. In
addition, notwithstanding any other provision of this Agreement, the Holders
understand that there may be periods during which GraphOn's Board of Directors
may determine, in good faith, that it is in the best interest of GraphOn and its
stockholders to defer disclosure of non-public information until such
information has reached a more advanced stage and that during such periods sales
of Registrable Securities and the effectiveness of any registration statement
covering Registrable Securities may be suspended or delayed. The Holders agree
that upon receipt of any notice from GraphOn of the development of any
non-public information, such Holders will forthwith discontinue such Holders'
disposition of Registrable Securities pursuant to the registration statement
relating to such Registrable Securities until such Holders' receipt of copies of
an appropriately supplemented or amended prospectus and, if so directed by
GraphOn, such Holders will use their best efforts to deliver to GraphOn (at
GraphOn's expense) all copies, other than permanent file copies then in such
Holders' possession, of the prospectus relating to such Registrable Securities
current at the time of receipt of such notice. In the event GraphOn shall give
any such notice, the applicable time period during which a Registration
Statement is to remain effective shall be extended by the number of days during
the period from and including the date of the giving of such notice to and
including the date when each seller of a Registrable Share covered by such
registration statement shall have received the copies of the appropriate
supplemented or amended prospectus.

  1.4 Termination of Obligations. The obligations of the Company pursuant to
Section 1.2 hereof shall cease and terminate upon the earlier to occur of (a)
such time as all of the Registrable Shares have been resold, (b) such time as
all of the Registrable Shares may be resold in a three-month period pursuant to
Rule 144 or (c) the second anniversary of the Closing Date.

  1.5 Rights Upon Transfer. No Transferee of Registrable Shares shall be
entitled to have the shares transferred to it covered by the Registration
Statement unless such Transferee agrees in writing to be bound by all of the
provisions of this Holder Agreement applicable to such Holder and to return a
properly completed and executed Registration Statement Questionnaire and
Investment Suitability Questionnaire (the "Questionnaires") furnished by
GraphOn.

Section 2. INDEMNIFICATION OBLIGATIONS; APPOINTMENT OF SHAREHOLDERS'
REPRESENTATIVE

  2.1  Acknowledgement of Obligation. Each Holder acknowledges such Holders'
obligation, pursuant to Section 9 of the Reorganization Agreement, and subject
to any limitations contained therein, to hold harmless and indemnify each of the
Indemnitees from and against any, and to compensate and reimburse each of the
Indemnitees for any Damages directly or indirectly suffered or incurred by any
Indemnitee or to which any Indemnitee may otherwise be subject; provided,


                                       3


however, that, except as otherwise set forth in Section 9 of the Reorganization
Agreement, each Holder's obligation pursuant to Section 9 of the Reorganization

Representative, on behalf of each Holder, to:

           (i) receive all notices or documents given or to be given to any of
the Holders by GraphOn pursuant hereto or to the Reorganization Agreement or
Escrow Agreement or in connection herewith or therewith and to receive and


                                       4

connection with this Holder Agreement, the Reorganization Agreement or the
Escrow Agreement and the transactions contemplated hereby or thereby as the
Shareholders' Representative may in its sole discretion deem appropriate; and

           (iv) take such action on behalf of any of the Holders as the
Shareholders' Representative may in its sole discretion deem appropriate in
respect of:

              (A) waiving any inaccuracies in the representations or warranties
of GraphOn contained in the Reorganization Agreement or in any document
delivered by GraphOn pursuant hereto or pursuant to the Reorganization
Agreement;

              (B) waiving the fulfillment of any of the conditions precedent to
GraphOn's obligations hereunder or pursuant to the Escrow Agreement;

              (C) taking such other action as the Shareholders' Representative
or any of the Holders are authorized to take under this Holder Agreement, the

Agreement, the Reorganization Agreement or the Escrow Agreement and the
transactions contemplated hereby and thereby; and

              (F) all such action as may be necessary after the Closing Date to

indemnification is sought pursuant to Section 9 of the Reorganization Agreement
and any waiver of any obligation of GraphOn, Surviving Entity I or the Surviving
Entity.

All actions, decisions and instructions of the Shareholders' Representative
shall be conclusive and binding upon all of the Holders and no Holder nor any
other Person shall have any claim or cause of action against the Shareholders'
Representative, and the Shareholders' Representative shall have no liability to


                                       5


any Holders or any other Person, for any action taken, decision made or
instruction given by the Shareholders' Representative in connection with the
Escrow Agreement, this Holder Agreement or the Reorganization Agreement, except
in the case of its own willful misconduct.

      (c) Indemnification of Shareholders' Representative. The Shareholders'
Representative shall incur no liability to the Holders or the Escrow Agent or
any other person with respect to any action taken or suffered by it in reliance
upon any note, direction, instruction, consent, statement or other documents
reasonably believed by the Shareholders' Representative to be genuinely and duly
authorized by a majority in interest of the Holders (or the successors or
assigns thereto), nor for other action or inaction taken or omitted in good
faith in connection herewith or with the Escrow Agreement, in any case except
for liability to the Holders for its own willful misconduct. The Shareholders'
Representative shall be indemnified by the Holders out of the Reimbursement Fund
for and shall be held harmless against any loss, liability or expense incurred
by the Shareholders' Representative or any of its Affiliates and any of its
partners, directors, officers, employees, agents, Holders, consultants,
attorneys, accountants, advisors, brokers, representatives or controlling
persons, in each case relating to the Shareholders' Representative's conduct as
Shareholders' Representative, other than such losses, liabilities or expenses
resulting from the Shareholders' Representative's willful misconduct in
connection with their performance under this Holder Agreement, the
Reorganization Agreement and the Escrow Agreement. This indemnification shall
survive the termination of this Agreement. The costs of such indemnification
(including the costs and expenses of enforcing this right of indemnification)
shall be paid from the principal portion of the Reimbursement Fund. For all
purposes hereunder, a majority-in-interest of the Holders shall be determined on
the basis of each such Holder's ownership of GraphOn Common Stock received upon
conversion of the Holder's shares of NES Common Stock in connection with the
Merger immediately following the Effective Time of Merger I. The Escrow Agent
shall from time to time sell such amount of the Reimbursement Shares as
necessary to pay the Shareholders' Representative's costs and expenses, to the
extent required by this Section 2.2(c).

      (d) Reasonable Reliance. In the performance of its duties hereunder, the
Shareholders' Representative shall be entitled to rely upon any document or
instrument reasonably believed by it to be genuine, accurate as to content and
signed by any Holders or GraphOn. The Shareholders' Representative may assume
that any person purporting to give any notice in accordance with the provisions
hereof has been duly authorized to do so.

      (e) Attorney-in-Fact.

           (i) The Shareholders' Representative is hereby appointed and
constituted the true and lawful attorney-in-fact of each Holder, with full power
in his, her or its name and on his, her or its behalf to act according to the
terms of this Holder Agreement, the Reorganization Agreement and the Escrow
Agreement in the absolute discretion of the Shareholders' Representative; and in
general to do all things and to perform all acts including, without limitation,
executing and delivering the Escrow Agreement and any other agreements,
certificates, receipts, instructions, notices or instruments contemplated by or
deemed advisable in connection with the Escrow Agreement.

                                       6


           (ii) This power of attorney and all authority hereby conferred is
granted and shall be irrevocable and shall not be terminated by any act of any
Holders, by operation of law, whether by such Holder's death, disability,
protective supervision or any other event. Without limiting the foregoing, this
power of attorney is to ensure the performance of a special obligation and,
accordingly, each Holder hereby renounces its, his or her right to renounce this
power of attorney unilaterally any time before the end of the Escrow Period (as
such term is defined in the Escrow Agreement).

           (iii) Each Holder hereby waives any and all defenses which may be
available to contest, negate or disaffirm the action of the Shareholders'
Representative taken in good faith under the Escrow Agreement.

           (iv) Notwithstanding the power of attorney granted in this Section
2.2, no agreement, instrument, acknowledgement or other act or document shall be
ineffective by reason only of a Holder having signed or given such directly
instead of the Shareholders' Representative.

      (f) Liability. If the Shareholders' Representative is required by the
terms of the Escrow Agreement to determine the occurrence of any event or
contingency, the Shareholders' Representative shall, in making such
determination, be liable to the Holders only for its proven willful misconduct
as determined in light of all the circumstances, including the time and
facilities available to it in the ordinary conduct of business. In determining
the occurrence of any such event or contingency, the Shareholders'
Representative may request from any of the Holders or any other person such
reasonable additional evidence as the Shareholders' Representative in its sole
discretion may deem necessary to determine any fact relating to the occurrence
of such event or contingency, and may at any time inquire of and consult with
others, including any of the Holders, and the Shareholders' Representative shall
not be liable to any Holder for any Damages resulting from its delay in acting
hereunder pending receipt and examination of additional evidence requested by
it.

      (g) Orders. The Shareholders' Representative is authorized, in its sole
discretion, to comply with final, nonappealable orders or decisions issued or
process entered by any court of competent jurisdiction or arbitrator with
respect to the Escrow Fund or the Reimbursement Fund. If any portion of the
Reimbursement Fund is disbursed to the Shareholders' Representative and is at
any time attached, garnished or levied upon under any court order, or in case
the payment, assignment, transfer, conveyance or delivery of any such property
shall be stayed or enjoined by any court order, or in case any order, judgment
or decree shall be made or entered by any court affecting such property or any
part thereof, then and in any such event, the Shareholders' Representative is
authorized, in its sole discretion, but in good faith, to rely upon and comply
with any such order, writ, judgment or decree that it is advised by legal
counsel selected by it is binding upon it without the need for appeal or other
action; and if the Shareholders' Representative complies with any such order,
writ, judgment or decree, it shall not be liable to any Holder or to any other
Person by reason of such compliance even though such order, writ, judgment or
decree may be subsequently reversed, modified, annulled, set aside or vacated.

                                       7


      (h) Removal of a Shareholders' Representative; Authority of Successor
Shareholders' Representative. Holders who in the aggregate hold a majority of
the shares in the Escrow Fund shall have the right at any time during the term
of the Escrow Agreement to remove the then-acting Shareholders' Representative
and to appoint a successor Shareholders' Representative; provided, however, that
neither such removal of any then acting Shareholders' Representative nor such
appointment of the successor Shareholders' Representative shall be effective
until the delivery to the Escrow Agent of executed counterparts of a writing
signed by each such Holder with respect to such removal and appointment,
together with an acknowledgment signed by the successor Shareholders'
Representative appointed in such writing that he or she accepts the
responsibility of being the successor Shareholders' Representative and agrees to
perform and be bound by all of the provisions of this Agreement applicable to
the Shareholders' Representative. Each successor Shareholders' Representative
shall have all of the power, authority, rights and privileges conferred by this
Agreement upon the original Shareholders' Representative, and the term
"Shareholders' Representative" as used herein and in the Escrow Agreement shall
be deemed to include any interim or successor Shareholders' Representative.

      (i) Expenses of the Shareholders' Representative. The Holders (i) shall
have no claim or cause of action against, may not assert any claim against, and
shall indemnify and hold harmless the Shareholders' Representative and its
Affiliates and any of their respective partners, directors, officers, employees,
agents, Holders, consultants, attorneys, accountants, advisors, brokers,
representatives or controlling persons, as provided for in Section 2.2(c) above
and (ii) shall pay to the Shareholders' Representative, promptly upon request,
such Holder's pro rata share of any amounts paid by the Shareholders'
Representative on behalf of the Holders and all costs and expenses (including
legal, accounting and other advisors' fees and expenses, if applicable)
reasonably incurred by the Shareholders' Representative in connection with the
protection, defense or enforcement of any rights under this Holder Agreement or
the Escrow Agreement.

      (j) Irrevocable Appointment. Subject to Section 2.2(i), the appointment of
the Shareholders' Representative hereunder is irrevocable and any action taken
by the Shareholders' Representative pursuant to the authority granted in this
Section 2.2 shall be effective and absolutely binding on each Holder thereof
notwithstanding any contrary action of, or direction from any Holder, except for
actions taken by the Shareholders' Representative that constitute willful
misconduct.

  2.3 Defense of Third-Party Claims. In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against
Surviving Entity I, against the Surviving Entity, against GraphOn or against any
other Person) with respect to which an Indemnitee may seek indemnification
pursuant to Section 9 of the Reorganization Agreement, GraphOn shall have the
right, at its election, to proceed with the defense of such claim or Legal
Proceeding on its own. If GraphOn so proceeds with the defense of any such claim
or Legal Proceeding:

      (a) all reasonable expenses relating to the defense of such claim or Legal
Proceeding shall be borne and paid by the Holders;

                                       8


      (b) each Holder shall make available to GraphOn any documents and
materials in his possession or control that may be necessary to the defense of
such claim or Legal Proceeding; and

      (c) GraphOn shall have the right to settle, adjust or compromise such
claim or Legal Proceeding with the consent of the Shareholders' Representative;
provided, however, that such consent shall not be unreasonably withheld.

GraphOn shall give the Shareholders' Representative prompt notice of the
commencement of any such Legal Proceeding against GraphOn, against Surviving
Entity I or against the Surviving Entity; provided, however, that any failure on
the part of GraphOn to so notify the Shareholders' Representative shall not
limit any indemnification obligations under Section 9 of the Reorganization
Agreement (except to the extent such failure materially prejudices the defense
of such Legal Proceeding).

  2.4 Exercise of Remedies by Indemnitees Other Than GraphOn. No Indemnitee
(other than GraphOn or any successor thereto or assign thereof) shall be
permitted to assert any indemnification claim or exercise any other remedy under
the Reorganization Agreement or this Holder Agreement unless GraphOn (or any
successor thereto or assign thereof) shall have consented to the assertion of
such indemnification claim or the exercise of such other remedy.

Section 3. CERTIFICATION

  3.1  Representations, Warranties and Certification of the Holders.  Each
Holder represents, warrants and certifies to GraphOn as follows.

      (a) Before giving effect to the Merger: (i) each Holder is the beneficial
owner of the number of shares of NES Common Stock set forth opposite the
Holder's name on the Schedule of Holders attached hereto as Exhibit A (the
"Shares"); (ii) each Holder has good and valid title to the Shares free and
clear of any Encumbrances; (iii) the Shares are the only outstanding shares of
the capital stock of NES beneficially owned by the Holder; and (iv) the Holder
has the sole power to vote all of the Shares at any meeting of the stockholders
of NES and the sole power to act by written consent with respect to the Shares
in lieu of any such meeting. The Holder has not appointed or granted any proxy
or entered into any agreement, contract, commitment or understanding with
respect to any of the Shares.

      (b) The Holder has the absolute and unrestricted right, power, authority
and capacity to enter into, execute, deliver and perform all of his obligations
under this Holder Agreement and under each other agreement, document or
instrument referred to in or contemplated by this Holder Agreement to which the
Holder is or is to become a party (each such other agreement, document or
instrument being referred to herein as an "Other Applicable Document").

      (c) This Holder Agreement and each Other Applicable Document (i) has been
(or will when executed by the Holder be) duly and validly executed by the Holder
and (ii) constitutes (or will when executed by the Holder constitute) a valid
and binding obligation of the Holder, enforceable against the Holder in


                                       9


accordance with its terms, subject to laws of general application relating to
bankruptcy, insolvency and the relief of debtors, and to general equitable
principles.

      (d) Neither the execution, delivery or performance of this Holder
Agreement or of any Other Applicable Document, nor the consummation of the
Merger or any of the other transactions contemplated by this Holder Agreement,
the Reorganization Agreement or by any Other Applicable Document, will directly
or indirectly: (i) result in any violation or breach of any agreement or other
instrument to which the Holder is a party or by which the Holder or any of the
Shares is bound or affected; or (ii) result in a violation of any Legal
Requirement or order to which the Holder or any of the Shares is subject. No
authorization, consent or approval of, or notice to, any Person is required to
be obtained or given by the Holder in connection with the execution, delivery or
performance of the Reorganization Agreement or of any Other Applicable Document.

      (e) There is no Legal Proceeding by or before any Governmental Body
pending or, to the knowledge of the Holder, threatened against the Holder that
challenges or would challenge the execution, delivery or performance of this
Holder Agreement or of any Other Applicable Document or the taking of any of the
actions required to be taken under this Holder Agreement or under any Other
Applicable Document.

      (f) The Holder is aware that (i) the GraphOn Common Stock to be issued to
the Holder in the Merger will not be issued pursuant to a registration statement
under the Securities Act, but will instead be issued in reliance on the
exemption from registration set forth in Regulation D under the Act and (ii)
neither the Transaction nor the issuance of such GraphOn Common Stock has been
approved or reviewed by the SEC or by any other Governmental Body.

      (g) The Holder is aware that the GraphOn Common Stock to be issued in the
Merger cannot be offered, sold or otherwise transferred, assigned, pledged or
hypothecated unless such GraphOn Common Stock is registered under the Securities
Act or unless an exemption from registration is available.

      (h) The GraphOn Common Stock to be issued to the Holder in the Merger will
be acquired by the Holder for investment purposes only and for the Holder's own
account, and not with a view to, or for resale in connection with, any
unregistered distribution thereof.

      (i) The Holder is knowledgeable, sophisticated and experienced in making,
and is qualified to make, decisions with respect to investments in securities
presenting investment decisions like that involved in the Holder's contemplated
investment in the GraphOn Common Stock to be issued in connection with the
Merger.

      (j) The Holder is an "accredited investor," as that term is defined in
Rule 501 under the Securities Act.

      (k) The Holder understands that stop transfer instructions will be given
to GraphOn's transfer agent with respect to the GraphOn Common Stock to be
issued to the Holder in the Merger, and that there will be placed on the
certificate or certificates representing such GraphOn Common Stock a legend
identical or similar in effect to the following legend (together with any other
legend or legends required by applicable state securities laws or otherwise):

                                       10


           "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
           UNDER THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
           SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED
           UNLESS REGISTERED UNDER THE ACT OR UNLESS AN EXEMPTION FROM THE
           REGISTRATION REQUIREMENTS OF THE ACT IS AVAILABLE."

  3.2 Reliance. The Holder acknowledges that GraphOn will rely on the Holder's
representations, warranties and certification set forth in Section 3.1 above for
purposes of determining the Holder's suitability as an investor in GraphOn
Common Stock and for purposes of confirming the availability of an exemption
from the registration requirements of the Securities Act for the issuance of
shares of GraphOn Common Stock in the Merger.

  3.3 Prohibitions Against Transfer. The Holder understands and acknowledges
that it shall not effect any sale, transfer or other disposition, or any
assignment, pledge or hypothecation, of any shares of GraphOn Common Stock that
he is to receive in the Merger unless:

      (i) such sale, transfer, disposition, assignment, pledge or hypothecation
has been registered under the Securities Act;

      (ii) counsel reasonably satisfactory to GraphOn shall have advised GraphOn
in a written opinion letter (satisfactory in form and content to GraphOn), upon
which GraphOn may rely, that such sale, transfer, disposition, assignment,
pledge or hypothecation will be exempt from registration under the Securities
Act; or

      (iii) an authorized representative of the SEC shall have rendered written
advice to the Holder to the effect that the SEC would take no action, or that
the staff of the SEC would not recommend that the SEC take action, with respect
to such sale, transfer, disposition, assignment, pledge or hypothecation and a
copy of such written advice and all other related communications with the SEC
shall have been delivered to GraphOn.

  3.4 No "Net Short" Position. For so long as Holder owns any Shares, such
Holder shall not maintain a Net Short Position. For purposes of this Section, a
"Net Short Position" by a person means a position whereby such person has
executed one or more sales of GraphOn Common Stock that is marked as a short
sale and that is executed at a time when such Holder has no equivalent
offsetting long position in the GraphOn Common Stock. For purposes of
determining whether a Holder has an equivalent offsetting long position in the
GraphOn Common Stock, all GraphOn Common Stock that is owned by such Holder
shall be deemed to be held long by such Holder.

  3.5 Questionnaires. Holder has completed or caused to be completed and
delivered to GraphOn the Questionnaires, and the answers to the questions in the
Questionnaires are true and correct as of the date of this Agreement; provided,
that the Holders shall be entitled to update such information by providing
written notice thereof to GraphOn before the effective date of the Registration
Statement.

                                       11

  4.8 Governing Law. This Holder Agreement shall be construed in accordance
with, and governed in all respects by, the internal laws of the State of
California (without giving effect to principles of conflicts of laws).

  4.9 Successors and Assigns. This Holder Agreement shall be binding upon: each

  4.10  Remedies Cumulative.  The rights and remedies of the parties hereto
shall be cumulative (and not alternative).

right, privilege or remedy.

      (b) No Person shall be deemed to have waived any claim arising out of this

unenforceable, the parties hereto agree that the court making such determination
shall have the power to limit the term or provision, to delete specific words or
phrases, or to replace any invalid or unenforceable term or provision with a
term or provision that is valid and enforceable and that comes closest to
expressing the intention of the invalid or unenforceable term or provision, and
this Holder Agreement shall be enforceable as so modified. In the event such
court does not exercise the power granted to it in the prior sentence, the
parties hereto agree to replace such invalid or unenforceable term or provision
with a valid and enforceable term or provision that will achieve, to the extent
possible, the economic, business and other purposes of such invalid or
unenforceable term.

applied in the construction or interpretation of this Agreement.

      (c) As used in this Holder Agreement, the words "include" and "including,"
