          WHEREAS, Licensor is willing to allow Licensee to use and occupy the
Licensed Premises for the License Period on the terms, covenants and conditions
hereinafter set forth;

          NOW, THEREFORE, Licensor and Licensee covenant and agree as follows:

          1. Licensor hereby grants to Licensee, and Licensee hereby accepts
from Licensor, a License to use and occupy the Licensed Premises during the

to any Office Services.

          2. Licensee shall use and occupy the Licensed Premises in accordance
with the terms, covenants and conditions of the Lease to be observed by Licensor

calendar month commencing on the License Effective Date, at the office of
Licensor or such other place as Licensor may designate, without any setoffs or
deductions whatsoever, except that the License Fee shall be pro rated from the
License Effective Date to July 31, 2004.

          4. This Agreement does not and shall not be deemed to constitute a

confer upon Licensee any right, title, estate, or interest in the Licensed
Premises. This Agreement grants to Licensee a personal privilege to use and
occupy the Licensed Premises for the License Period on the terms and conditions
set forth herein. The Licensor represents and warrants to Licensee that the
granting of the License to Licensee, as described in this Agreement, does not
violate any term or provision of the Lease.

Agreement or the License, nor shall Licensee permit or suffer any other person
or entity to use or occupy all or any part of the Licensed Premises.

          6. Either Licensor or Licensee may, at its option with or without
cause, terminate this Agreement upon thirty (30) days prior written notice to
the other party. Upon the expiration or other termination of the License Period,
Licensee shall quit and surrender to Licensor the Licensed Premises, and
Licensee shall remove all of its property located on the Licensed Premises, if
any. Nothing herein contained shall be deemed to permit Licensee to retain
possession of the Licensed Premises after the License Period.

          7. Each party shall indemnify and save harmless the other and its
agents against and from (i) any and all claims against the indemnified party of
whatever nature arising from any act, omission or negligence of the indemnifying
party, its contractors, licensees, agents, servants, employees, invitees or

damage occurring within the Premises or in the Building, where such accident,
injury or damage results or is claimed to have resulted from any act or omission

any breach, violation or non-performance of any covenant, condition or agreement
in this Agreement on the part of the indemnifying party to be fulfilled, kept,
observed and performed. The provisions of this paragraph 7 shall survive the
expiration or earlier termination of this Agreement.

obligations hereunder.

          9. Licensee shall obtain and maintain all the insurance coverage and
policies required of Licensor pursuant to the Lease with regard to the Licensed
Premises, except that all policies required to name Landlord as additional
insured shall also name Licensor as an insured.

Licensed Premises and agrees to take same in its condition "as is", as of the
License Effective Date, and Licensor shall have no obligation to alter, improve,

               AMENDMENT NO. 2 TO AGREEMENT AND PLAN OF MERGER

     This Amendment No. 2 to Merger Agreement dated as of July 5, 2006 (this
"AMENDMENT"), among Halo Technology Holdings, Inc., a Nevada corporation
("PARENT"), UCA Merger Sub, Inc., a Delaware corporation and wholly-owned
subsidiary of Parent ("MERGER SUB") and Unify Corporation, a Delaware
corporation (the "COMPANY").

                                   WITNESSETH:

     WHEREAS, Parent, Merger Sub and the Company are parties to that certain
Agreement and Plan of Merger, dated as of March 14, 2006 (as amended, the

     NOW, THEREFORE, in consideration of the premises and of the mutual

by the following:

     (b) CONVERSION OF COMPANY COMMON STOCK. Subject to Sections 2.1(e) and

     than shares to be cancelled in accordance with Section 2.1(a) and shares
     exercising appraisal rights in accordance with Section 2.1(f)) at the
     Effective Time shall be converted into the right to receive 0.595 of one
     share of Parent Common Stock (the " Exchange Ratio "). The shares of Parent
     Common Stock issued in exchange for Company Common Stock, together with the
     Substitute Options and the Substitute Warrants, constitutes the " Merger
     Consideration ." As of the Effective Time and without any action on the
     part of the holders thereof, all such shares of Company Common Stock shall
     no longer be outstanding and shall automatically be cancelled and retired
     and shall cease to exist, and each holder of a certificate or certificates
     that immediately prior to the Effective Time represented outstanding shares
     of Company Common Stock (the " Certificates ") shall cease to have any
     rights with respect thereto, except the right to receive (i) the Merger
     Consideration and (ii) certain dividends and other distributions in
     accordance with Section 2.2(c).

2.   AMENDMENT TO SECTION 2.1(e). Section 2.1(e) is hereby amended and replaced

     (e) ADJUSTMENTS TO EXCHANGE RATIO. The Exchange Ratio shall be adjusted to
     reflect appropriately the effect of any stock split, reverse stock split,
     stock dividend (including any dividend or distribution of securities
     convertible into or exercisable or exchangeable for Parent Common Stock or
     Company Common Stock), extraordinary dividend, reorganization,
     recapitalization, reclassification, combination, exchange of shares or
     other like change with respect to Parent Common Stock or Company Common
     Stock occurring

     or having a record date on or after the date hereof and prior to the
     Effective Time. Further, in the event that at the Effective Time the
     Company has cash on hand which is less than Two Million One Hundred
     Thousand Dollars ($2,100,000), the Exchange Ratio shall be reduced to the
     ratio determined by dividing (a) 17,478,840 minus the quotient of (x) (A)
     Two Million One Hundred Thousand Dollars ($2,100,000) minus (B) the amount
     of cash the Company has on hand at the Effective Time, divided by (y)
     $1.20, by (b) 29,376,201.

3.   AMENDMENT TO SECTION 7.2. Section 7.2 is hereby amended by adding the
following Section 7.2(g) to the end thereof:

     (g) ADJUSTMENTS TO EXCHANGE RATIO. At the Effective Time, the Company shall
     have cash on hand in an amount equal to or in excess of Two Million One
     Hundred Thousand Dollars ($2,100,000).

     (e) ADDITIONAL INVESTMENT. Parent shall have received at least Three

     any investment made by Special Situations Funds) between the date hereof
     and the Effective Time."

5.   AMENDMENT TO SECTION 7.3(f). Section 7.3(f) is hereby amended and replaced
by the following:

         (f) CAPITALIZATION. On or prior to the Effective Time (i) the holders
         of outstanding shares of the Parent's Preferred Stock (other than the
         Parent's Series D Preferred Stock) shall have converted such shares of
         preferred stock into common stock of Parent, (ii) the holders of
         convertible promissory notes of Parent listed on Schedule 7.3(f)(i)
         shall have converted such promissory notes into shares of Common Stock
         of Parent, and (iii) the holders of the promissory notes of Parent
         listed on Schedule 7.3(f)(ii) shall have restructured the payment terms
         to be no less favorable to Parent than those described on Schedule
         7.3(f)(ii).

replaced by the schedule attached hereto as Exhibit A.

to this Amendment.
