If you and we are parties to a master agreement that governs transactions of
this type (whether in the form of the 1992 ISDA Master Agreement

        any reason, the remaining terms, provisions, covenants, and conditions
        hereof shall continue in full force and effect as if this Agreement had
        been executed with the invalid or unenforceable portion eliminated, so
        long as this Agreement as so modified continues to express, without

        replace any invalid or unenforceable term, provision, covenant or

            to be required to return any such payment to Counterparty (or any
            duly authorized representative thereof) or whether otherwise
            pursuant to appropriate proceedings to return to Counterparty (or
            any duly authorized representative thereof)) or UBS AG otherwise
            returns to Counterparty (or any duly authorized representative
            thereof) upon demand of Counterparty (or any duly authorized
            representative thereof) any portion of such payment, then: (a) the
            occurrence of an event described in Section 5(a) of the Agreement
            with respect to Counterparty shall not constitute an Event of
            Default or Potential Event of Default with respect to Counterparty
            as the Defaulting Party in respect of this Transaction and (b) UBS
            AG shall be entitled to designate an Early Termination Date pursuant

            a result of a Termination Event set forth in either Section 5(b)(i)
            or Section 5(b)(ii) of the Agreement with respect to UBS AG as the
            Affected Party or Section 5(b)(iii) of the Agreement with respect to

        of the State of New York shall govern their rights and duties in whole
        without regard to the conflict of law provisions thereof (other than New
        York General Obligations Law Sections 5-1401 and 5-1402).

(xiv)   Non-Recourse. Notwithstanding any provision herein or in the ISDA Form
        to the contrary, the obligations of Counterparty hereunder are limited
        recourse obligations of Counterparty, payable solely from the Trust
        Estate (as defined in the Pooling and Servicing Agreement) and the
        proceeds thereof to satisfy Counterparty's obligations hereunder. In the
        event that the Trust Estate and proceeds thereof should be insufficient
        to satisfy all claims outstanding and following the realization of the
        Trust Estate and the distribution of the proceeds thereof in accordance
        with the Pooling and Servicing Agreement, any claims against or
        obligations of Counterparty under the ISDA Form or any other
        confirmation thereunder, still outstanding shall be extinguished and
        thereafter not revive.

(xv)    Set-Off. Notwithstanding any provision of this Agreement or any other
        existing or future agreement, each party irrevocably waives any and all
        rights it may have to set off, net, recoup or otherwise withhold or
        suspend or condition payment or performance of any obligation between it
        and the other party hereunder against any obligation between it and the
        other party under any other agreements. The provisions for Set-off set
        forth in Section 6(e) of the Agreement shall not apply for purposes of
        this Transaction; provided, however, that upon the designation of any
        Early Termination Date, in addition to, and not in limitation of any
        other right or remedy under applicable law, UBS AG may, by notice to
        Counterparty require Counterparty to set off any sum or obligation that
        UBS AG owed to Counterparty against any collateral currently held by
        Counterparty that UBS AG has posted to Counterparty, and Counterparty
        shall effect such setoff promptly, if and to the extent permitted to do
        so under applicable law, provided that Counterparty's exercise of this
        setoff is not stayed or otherwise delayed by order of any court,
        regulatory authority or other governmental agency or any receiver other
        person appointed in respect of UBS AG or any of its property.

(xvi)   Proceedings. UBS AG covenants and agrees that it will not institute
        against or join any other person in instituting against the Counterparty
        any bankruptcy, reorganization, arrangement, insolvency, winding up or
        liquidation proceedings, or other proceedings under any United States
        federal or state law, or other bankruptcy, insolvency, liquidation, or
        similar law, in connection with any obligations relating to this
        Transaction or otherwise prior to the date that is one year and one day
        or, if longer, the applicable preference period after all the
        Certificates (as defined below) have been paid in full; provided, that
        this paragraph shall not restrict or prohibit UBS AG, after the filing
        of any proceeding filed independently of UBS AG, from joining any other
        person, including without limitation the Master Servicer, in any
        bankruptcy, reorganization, arrangement, insolvency, moratorium,
        liquidation or other analogous proceedings relating to Counterparty
        under any bankruptcy or similar law.

(xvii)  The ISDA Form is hereby amended as follows: for the purposes of this
        Transaction, the word "third" shall be replaced by he word "first" in
        the third line of Section 5(a)(i) of the ISDA Form; provided, however,
        that notwithstanding the foregoing, an Event of Default shall not occur
        under either if, as demonstrated to the reasonable satisfaction of the
        other party, (a) the failure to pay or deliver is caused by an error or
        omission of an administrative or operational nature; and (b) funds or
        the relevant instrument were available to such party to enable it to
        make the relevant payment or delivery when due; and (c) such relevant

(xxiii) Compliance with Regulation AB.

(i) UBS AG agrees and acknowledges that Wells Fargo Asset Securities Corporation
(the "Depositor") is required under Regulation AB under the Securities Act of
1933, as amended, and the Securities Exchange Act of 1934, as amended (the
"Exchange Act") ("Regulation AB"), to disclose certain financial information
regarding UBS AG, depending on the aggregate "Significance Percentage" (as
defined in Item 1115 of Regulation AB) of all Transactions under this Agreement,
together with any other transactions that fall within the meaning of "derivative
contracts" for the purposes of Item 1115 of Regulation AB between UBS AG and
Counterparty, as calculated from time to time in accordance with the Calculation
Methodology (as defined below).

(ii) It shall be a swap disclosure event ("Swap Disclosure Event") if, on any
Business Day after the date hereof, the Depositor notifies UBS AG the
Significance Percentage has reached one of the thresholds for significance of
derivative contracts set forth in Item 1115 of Regulation AB (based on a
reasonable determination by the Depositor, in good faith and using the
Calculation Methodology, of such Significance Percentage).

expense, shall (a) provide to the Depositor the applicable Swap Financial
Disclosure (as defined below), (b) secure another entity to replace UBS AG as
party to this Agreement on terms substantially similar to this Agreement and
subject to prior notification to the Swap Rating Agencies, which entity (or a

satisfies the Rating Agency Condition) and which entity is able to provide the
appropriate Swap Financial Disclosure or (c) obtain a guaranty of UBS AG's
obligations under this Agreement from an affiliate of UBS AG that is able to
comply with the financial information disclosure requirements of Item 1115 of
Regulation AB, such that disclosure provided in respect of the affiliate will,
in the judgment of counsel to the Depositor, satisfy any disclosure requirements
applicable to the Swap Provider, cause such affiliate to provide Swap Financial
Disclosure and cause such affiliate to provide indemnity for the Swap Financial
Disclosure that is reasonably acceptable to the Depositor. If permitted by
Regulation AB, any required Swap Financial Disclosure may be provided by
reference to or incorporation by reference from reports filed pursuant to the
Exchange Act.

(iv) UBS AG agrees that, in the event that UBS AG provides Swap Financial
Disclosure to the Depositor in accordance with paragraph (iii)(a) above, or
causes its affiliate to provide Swap Financial Disclosure to the Depositor in
accordance with paragraph (iii)(c) above, it will indemnify and hold harmless
the Depositor, its respective directors or officers and any person controlling
the Depositor, from and against any and all losses, claims, damages and
liabilities (any "Damage") caused by any untrue statement or alleged untrue
statement of a material fact contained in such Swap Financial Disclosure or
caused by any omission or alleged omission to state in such Swap Financial
Disclosure a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading; provided, however that the foregoing shall not apply to
any Damage caused by the negligence or any willful action of the Depositor or
any other party (other than UBS AG or any of its affiliates or any of their
respective agents), including without limitation any failure to calculate the
Significance Percentage according to the terms of this Agreement or to make any
filing as and when required under Regulation AB.

(v) In the event that UBS AG provides the information referred to above, such
information shall be provided not later than five (5) business days prior to the
date in which the Master Servicer is required to file a Form 10-D for such
Distribution Date.

For the purposes hereof:

"Calculation Methodology" means such method for determining maximum probable
exposure of a derivative contract as reasonably determined by the Depositor.

  "Swap Financial Disclosure" means the financial information specified in Item
  1115 of Regulation AB relating to the applicable Significance Percentage and
  any necessary auditors consents relating to such financial information.

Additional Termination Events:

The following Additional Termination Events will apply to UBS AG:

1. Ratings Event. If a Ratings Event (as defined below) has occurred and UBS AG
has not complied with the requirements set forth in the succeeding paragraph
within the 30 day time period specified therein, then an Additional Termination
Event shall have occurred with respect to UBS AG and UBS AG shall be the sole
Affected Party with respect to such an Additional Termination Event.

      Rating Agency Downgrade:

      If a Ratings Event occurs with respect to UBS AG, then UBS AG shall, at
      its own expense, (i) assign this Transaction hereunder to a third party
      within thirty (30) days of such Ratings Event that meets or exceeds, or as
      to which any applicable credit support provider meets or exceeds, the
      Approved Rating Threshold (as defined below) on terms substantially
      similar to this Confirmation or (ii) deliver collateral acceptable in a
      form and amount acceptable to Fitch Ratings ("Fitch") and Moody's
      Investors Service Inc. ("Moody's) within thirty (30) days of such Ratings
      Event and subject to written confirmation from Fitch and Moody's that
      delivery of such collateral in the context of such downgrade will not
      result in a withdrawal, qualification or downgrade of the then current
      ratings assigned to the Certificates. For the avoidance of doubt, a
      downgrade of the rating on Wells Fargo Mortgage Backed Securities 2006-6
      Trust, Mortgage Pass-Through Certificates, Series 2006-6, Class I-A-22
      (the "Certificates") could occur in the event that UBS AG does not post
      sufficient collateral.

      For purposes of this Transaction, a "Ratings Event" shall occur with
      respect to UBS AG if its long term unsecured debt rating (the "Long Term
      Rating") ceases to be rated at least "A1" by Moody's Investors Service,
      Inc. or at least "A+ by Fitch Ratings (such ratings being referred to as
      the "Approved Ratings Threshold"), (unless, within 30 days after such
      withdrawal or downgrade Fitch and Moody's have reconfirmed the rating of
      the Certificates which were in effect immediately prior to such withdrawal
      or downgrade).

2. Swap Disclosure Event. If upon the occurrence of a Swap Disclosure Event (as
defined in paragraph (xxiii) above), UBS AG has not, within 5 business days
after such Swap Disclosure Event complied with any of the provisions set forth
in paragraph (xxiii) above, then an Additional Termination Event shall have
occurred with respect to UBS AG with UBS AG as the sole Affected Party with
respect to such Additional Termination Event.

Transfer, Amendment and Assignment:

No transfer, amendment, waiver, supplement, assignment or other modification of
this Transaction (other than the pledge of this Transaction to the Master
Servicer pursuant to the Pooling and Servicing Agreement) shall be permitted by
either party unless Moody's and Fitch have been provided notice of the same and
confirm in writing (including by facsimile transmission) that they will not
downgrade, qualify, withdraw or otherwise modify its then-current rating of the
Certificates; provided however that except with respect to a transfer at the
direction of UBS, nothing in this provision shall impose any obligation on UBS
to give notice to any rating agency.

Permitted Security Interest:

For purposes of Section 7 of the Agreement, UBS AG hereby consents to the
Permitted Security Interest.

"Permitted Security Interest" means the collateral assignment by the

 TERMS AND CONDITIONS 

 1.                Grant
    of Shares.   Premiere Global Services, Inc.
    (the “Company”) hereby grants
    to the Grantee named
    on Page 1 hereof (“Grantee”), subject
    to the restrictions and
    the other terms and conditions set forth in the Premiere Global Services, Inc.
    1995 Stock Plan (the “Plan”) and in this award agreement (this “Agreement”), the number of
    shares indicated on
    Page 1 hereof of the Company’s $0.01
    par value common stock (the “Shares”) . Capitalized terms
    used herein and not otherwise defined
    shall have the meanings assigned to such
    terms in the Plan. 

 2.                 Restrictions.
    The Shares are subject to each of the following restrictions. “Restricted
    Shares” mean
    those Shares that are subject to the restrictions imposed hereunder which
    restrictions have not then expired or terminated. Restricted Shares
    may not be sold, transferred, exchanged, assigned, pledged, hypothecated
    or otherwise encumbered. If Grantee’s employment with
    the Company or any Affiliate terminates for
    any reason other than as set forth in paragraphs (b),
    (c) or (d) of Section 3 hereof, then Grantee shall
    forfeit all of Grantee’s right, title and
    interest in and to the Restricted Shares
    as of the date of employment termination, such Restricted Shares
    shall revert to the Company immediately following the
    event of forfeiture. The restrictions imposed under
    this Section 2 shall apply to all shares of the Company’s common stock
    or other securities issued with respect
    to Restricted Shares hereunder in connection with
    any merger, reorganization, consolidation, recapitalization, stock dividend
    or other change in corporate structure affecting the common stock
    of the Company.

 3.                Expiration and Termination of Restrictions.
    The restrictions imposed under
    Section 2 will expire on the earliest to occur of the following (the
    period prior to such expiration being referred to herein as the “Restricted
    Period”):

      (a)       As
    to the  number of
    Shares on the respective dates specified on
    Page 1 hereof; provided Grantee is
    then still employed by
    the Company or
    an Affiliate; 

      (b)        As to all of the  unvested  Shares,
      on the date of  termination  of  Grantee’s   employment  by
      reason of death or  “Disability”  (as
      such term is defined  below); 

     (c)         As to all of the  unvested  Shares,
          upon the  occurrence  of a  “Change  in  Control”  (as
          such term is defined  below);  or

      (d)        As to the next tranche of  unvested  Shares,
            on the date of  termination  of  Grantee’s   employment  by
            the  Company   without   “Cause”  or
            by the  Grantee  for “Good  Reason”  (as
  such terms are defined below).

 For  purposes  of
    this  Agreement,   “Cause,”   “Disability,”   “Change  in  Control”  and “Good  Reason”  shall
    have the same  meaning  as in  Grantee’s  Fourth  Amended  and  Restated   Executive   Employment   Agreement,  dated
    as of  January  1,
    2005. 

 4.                 Delivery of
    Shares. The Shares will be registered in
    the name of Grantee as of the Grant Date and
    will be held by the Company during
    the Restricted Period in certificated or uncertificated form.
    If a certificate for Restricted Shares
    is issued during the Restricted Period
    with respect to such Shares, such certificate shall
    be registered in
    the name of Grantee and shall bear a legend
    in substantially the following form
    (in addition to
    any legend required under applicable state securities laws): 

 “This  certificate  and
    the shares of stock  represented  hereby
    are subject to the terms and  conditions   (including   forfeiture  and  restrictions  against  transfer)   contained  in
    a  Restricted  Stock  Agreement   between  the  registered  owner of the
    shares  represented  hereby
    and  Premiere  Global  Services,  Inc.  Release  from
    such terms and  conditions  shall be made only in  accordance  with
    the  provisions  of
    such  Agreement,  copies of which are
    on file in the offices of  Premiere  Global  Services,  Inc.” 

 Stock  certificates  for
    the Shares,  without  the
    first above legend, shall be  delivered  to  Grantee  or  Grantee’s   designee  upon request of  Grantee  after
    the  expiration  of
    the  Restricted  Period,
    but  delivery  may
    be  postponed  for
    such period as may be  required  for
    the  Company  with  reasonable   diligence  to
    comply if  deemed   advisable  by the  Company,  with  registration   requirements  under the  Securities  Act
    of 1933, as  amended,  listing  requirements  under the rules of
    any stock  exchange,  and  requirements  under
    any other law or  regulation   applicable  to
    the  issuance  or  transfer  of
    the Shares. 

 5.                Voting and Dividend Rights. Grantee, as beneficial owner
    of the Shares, shall have full voting and dividend rights
    with respect to the Shares during and after the Restricted Period. If Grantee forfeits
    any rights he or she may have under this Agreement in accordance with Section 3, Grantee shall
    no longer have any rights as a shareholder with
    respect to the Restricted Shares or any interest therein and Grantee shall
    no longer be entitled to receive dividends on
    such stock. In the event that for any reason Grantee shall
    have received dividends upon such stock after
    such forfeiture, Grantee shall
    repay to the Company any
    amount equal to such dividends.

 6.                 Changes in
    Capital Structure.
    The provisions of the Plan shall apply
    in the case of a change in the capital structure of
    the Company. Without limiting the foregoing, in
    the event of a subdivision of the outstanding Stock
    (stock-split), a declaration of
    a dividend payable in
    Stock, or a combination or consolidation of
    the outstanding Stock
    into a lesser number of shares, the Shares then subject to this Agreement shall automatically be adjusted proportionately.

 7.                No
      Right of Continued Employment. Nothing in
    this Agreement shall interfere with
    or limit in any way the right of the Company or any Affiliate to terminate Grantee’s employment at
    any time, nor confer upon Grantee any
    right to continue in
    the employ of the Company or
    any Affiliate.

 8.                 Payment of
    Taxes. Upon issuance of
    the Shares hereunder, Grantee may
    make an election to
    be taxed upon such award under Section 83(b) of the Code. To effect such election, Grantee may
    file an appropriate election with Internal Revenue Service within thirty (30)
    days after award of the Shares and otherwise in accordance with applicable Treasury Regulations. Grantee will, no later
    than the date as of which any amount related to the Shares first becomes includable in Grantee’s gross
    income for federal income tax purposes, pay to the Company, or
    make other arrangements satisfactory to the Committee, regarding payment of, any federal, state
    and local taxes of any kind required by
    law to be withheld with
    respect to such amount. The obligations of the Company under
    this Agreement will
    be conditional on such payment or arrangements, and
    the Company, and, where applicable, its Affiliates will,
    to the extent permitted by law, have the right
    to deduct any such taxes from any payment of
    any kind otherwise due to Grantee.

 9.                 Amendment.
    The Committee may
    amend, modify or terminate this Agreement without approval of Grantee; provided,
    however, that such amendment, modification or termination shall not, without
    Grantee’s consent, reduce or diminish the
    value of this award determined as
    if it had been fully vested (i.e., as if all restrictions on
    the Shares hereunder had expired) on the date of such amendment or termination.

 10.             Plan Controls.
    The terms contained in
    the Plan are incorporated into and made a part
    of this Agreement and
    this Agreement shall
    be governed by
    and construed in accordance with
    the Plan. In the event of any actual or alleged conflict between the provisions of
    the Plan and the provisions of
    this Agreement, the provisions of
    the Plan shall be controlling and determinative.

 11.              Successors.
    This Agreement shall
    be binding upon any successor of
    the Company, in accordance with the terms of this Agreement and
    the Plan. 

 12.              Severability.
     If any one or more of the provisions contained in this Agreement is deemed
    to be invalid, illegal or unenforceable, the
    other provisions of
    this Agreement will
    be construed and enforced as
    if the invalid, illegal
    or unenforceable provision had
    never been included.

 13.             Notice.  Notices and communications under
    this Agreement must be in writing and
    either personally delivered or
    sent by registered or certified United
    States mail, return receipt requested, postage prepaid.
