                        CONTINUING CORPORATE GUARANTY


           FOR  VALUE RECEIVED,  and in consideration  of any  loan or  other
 financial accommodation heretofore or hereafter at any time made or  granted
 to PC DYNAMICS OF  TEXAS, INC. ("Borrower"),  by FINOVA  CAPITAL CORPORATION
 ("Lender"),   the   undersigned,   PERFORMANCE   INTERCONNECT    CORPORATION
 ("Guarantor"), hereby agrees as follows:

           1.         Guaranty of  Obligations.   Guarantor  unconditionally,
 absolutely and  irrevocably  guarantees  the full  and  prompt  payment  and
 performance when due, whether by acceleration or otherwise, and at all times
 thereafter, of all  obligations of  Borrower to  Lender, howsoever  created,
 arising or evidenced, whether direct or indirect, absolute or contingent, or
 now or  hereafter existing  or  due or  to  become due,  including,  without
 limitation, under  or in  connection with  that  certain Loan  and  Security
 Agreement of even date, between Borrower  and Lender (the "Loan  Agreement")
 and each of the documents, instruments and agreements executed and delivered
 in connection therewith, as each may  be modified, amended, supplemented  or
 replaced from time  to time  (all such  obligations are  herein referred  to
 collectively as the "Liabilities", and all documents evidencing or  securing
 any of the Liabilities  are herein referred to,  collectively, as the  "Loan
 Documents"). This Continuing Corporate Guaranty (this "Continuing Guaranty")
 is a guaranty of payment and performance when due and not of collection.

           In the  event of any default by Borrower in making payment of,  or
 default by Borrower  in performance of,  any of  the Liabilities,  Guarantor
 agrees on demand by Lender to pay and perform all of the Liabilities as  are
 then or thereafter become  due and owing  or are to  be performed under  the
 terms of the Loan Documents.   Guarantor further agrees to pay all  expenses
 (including reasonable  attorneys' fees  and expenses)  paid or  incurred  by
 Lender in endeavoring to collect the  Liabilities, or any part thereof,  and
 in enforcing this Continuing Guaranty.

           2.         Continuing Nature  of  Guaranty and  Liabilities.  This
 Continuing Guaranty  shall  be  continuing  and  shall  not  be  discharged,
 impaired or affected by:

                 a.        the insolvency of Borrower or the payment in  full
       of all of the Liabilities at any time or from time to time;
<PAGE>
                 b.        the  power  or   authority  or  lack  thereof   of
       Borrower to incur the Liabilities:

                 c.         the  validity or invalidity  of any  of the  Loan
       Documents or the documents securing the same;

                 d.        the existence  or non-existence of  Borrower as  a
       legal entity;

                 e.        any transfer  by Borrower of  all or  any part  of
       any collateral in  which Lender has  been granted a  lien or  security
       interest pursuant to the Loan Documents;

                f.         any   statute   of   limitations   affecting   the
      liability  of Guarantor  under this  Continuing  Guaranty or  the  Loan
      Documents or the ability of Lender to enforce this Continuing  Guaranty
      or any provision of the Loan Documents; or

                g.         any right  of offset, counterclaim  or defense  of
      Guarantor, including, without limitation, those which have been  waived
      by Guarantor pursuant to Paragraph nine (9) hereof

           3.         Insolvency of Borrower  or Guarantor. Without  limiting
 the generality of any other provision hereof, Guarantor agrees that, in  the
 event of  the dissolution  or insolvency  of Borrower  or Guarantor  or  the
 inability of Borrower  or Guarantor to  pay their respective  debts as  they
 mature, or  an  assignment by  Borrower  or  Guarantor for  the  benefit  of
 creditors, or the institution  of any proceeding by  or against Borrower  or
 Guarantor alleging that Borrower or Guarantor is insolvent or unable to  pay
 their respective  debts  as  they  mature,  Guarantor  will  pay  to  Lender
 forthwith the full amount which would  be payable hereunder by Guarantor  if
 all of the Liabilities were then due and payable, whether or not such  event
 occurs at a time when any of the Liabilities are otherwise due and payable

           4.         Payment of  the Liabilities.  Any amounts  received  by
 Lender from whatever source on account of the Liabilities may be applied  by
 Lender toward the payment of such of  the Liabilities, and in such order  of
 application, as Lender may from time to time elect, and notwithstanding  any
 payments made by or for the account of Guarantor pursuant to this Continuing
 Guaranty.

           Guarantor  agrees that,  if at any  time all  or any  part of  any
 payment theretofore applied by Lender to  any of the Liabilities is or  must
 be rescinded or  returned by Lender  for any  reason whatsoever  (including,
 without  limitation,  the  insolvency,   bankruptcy  or  reorganization   of
 Borrower), such  Liabilities  shall, for  the  purposes of  this  Continuing
 Guaranty and to  the extent that  such payment is  or must  be rescinded  or
 returned, be  deemed to  have continued  in existence  notwithstanding  such
 application by Lender,  and this Continuing  Guaranty shall  continue to  be
 effective or be reinstated, as the case may be, as to such Liabilities,  all
 as though such application by Lender had not been made.
<PAGE>
           5.         Permitted Actions  of Lender.  Lender may  from time to
 time,  in  its sole discretion and  without notice to Guarantor, take any or
 all of the following actions:

                 a.        retain  or  obtain  a  security  interest  in  any
       assets  of  Borrower  or  any  third  party  to  secure  any  of   the
       Liabilities or any obligations of Guarantor hereunder;

                 b.        retain  or   obtain  the   primary  or   secondary
       obligation of any obligor or obligors, in addition to Guarantor,  with
       respect to any of the Liabilities

                 c.        extend or renew for  one or more periods  (whether
       or not longer than the original period), alter or exchange any of  the
       Liabilities;

                 d.        waive, ignore  or forbear  from taking  action  or
       otherwise exercising  any  of  its default  rights  or  remedies  with
       respect to any default by Borrower under the Loan Documents;

                 e.        release, waive  or  compromise any  obligation  of
       Guarantor hereunder  or any  obligation  of any  nature of  any  other
       obligor primarily or secondarily obligated with respect to any of  the
       Liabilities;

                 f.        release its  security interest  in, or  surrender,
       release or permit any  substitution or exchange for,  all or any  part
       of any collateral now or hereafter securing any of the Liabilities  or
       any obligation hereunder, or extend or  renew for one or more  periods
       (whether or not longer  than the original  period) or release,  waive,
       compromise, alter or  exchange any obligations  of any  nature of  any
       obligor with respect to any such property; and

                g.       demand  payment  or   performance  of  any  of   the
       Liabilities from Guarantor at any time  or from time to time,  whether
       or not Lender shall have exercised any of its rights or remedies  with
       respect to  any  property  securing any  of  the  Liabilities  or  any
       obligation hereunder or proceeded against any other obligor  primarily
       or secondarily  liable  for  payment or  performance  of  any  of  the
       Liabilities.

           6.         Specific Waivers.  Without, limiting the generality  of
 any other provision of this Continuing Guaranty, Guarantor hereby  expressly
 waives:
                 a. notice  of  the acceptance  by Lender  of this Continuing
                    Guaranty;

                 b. notice  of  the existence, creation. payment, nonpayment,
                    performance  or nonperformance  of  all  or  any  of  the
                    Liabilities;
<PAGE>
                 c. presentment, demand, notice of dishonor, protest,  notice
                    of protest and all other notices whatsoever with  respect
                    to the  payment or performance of the Liabilities  or the
                    amount thereof or any payment or performance by Guarantor
                    hereunder;

                 d. all   diligence  in   collection  or  protection  of   or
                    realization  upon the  Liabilities  or  any  thereof  any
                    obligation hereunder or any  security for or guaranty  of
                    any of the foregoing;

                 e. any  right to direct  or  affect the  manner or timing of
                    Lenders enforcement of its rights or remedies;

                 f. any  and  all defenses  which would  otherwise arise upon
                    the occurrence of any  event or contingency described  in
                    Paragraph 1 hereof  or upon the taking  of any action  by
                    Lender permitted hereunder;

                 g. any  defense,  right  of  set-off,  claim or counterclaim
                    whatsoever  and  any  and  all  other  rights,  benefits,
                    protections  and other  defenses available  to  Guarantor
                    now or at any time hereafter; and

                 h. all  other principles  or provisions of law, if any, that
                    conflict  with the  terms  of this  Continuing  Guaranty,
                    including,  without   limitation,  the   effect  of   any
                    circumstances that  may or  might constitute  a legal  or
                    equitable discharge of a guarantor or surety.

           7.   Irrevocability.  Guarantor hereby further  waives all  rights
 to revoke  this Continuing Guaranty at any time,  and all rights  to  revoke
 any agreement  executed by Guarantor at any time  to secure the payment  and
 performance of Guarantors obligations under this Continuing Guaranty.

           8.   Statutory  Waiver of Rights  and Defenses Regarding  Election
 of  Remedies. Guarantor waives  all rights and  defenses arising  out of  an
 election of remedies by Lender, even though that election of remedies,  such
 as  a nonjudicial  foreclosure with  respect to  security for  a  guaranteed
 obligation,   has   destroyed  Guarantor's   rights   of   subrogation   and
 reimbursement against  Borrower by the operation  of any applicable law,  or
 otherwise.

           9.   Subordination.  Guarantor  hereby subordinates  any  and  all
 indebtedness of  Borrower to Guarantor  to the full  and prompt payment  and
 performance of  all of the Liabilities.  Guarantor agrees that Lender  shall
 be  entitled to  receive payment  of all  Liabilities prior  to  Guarantor's
 receipt  of  payment of  any  amount  of any  indebtedness  of  Borrower  to
 Guarantor.   Any payments on  such indebtedness to  Guarantor, if Lender  so
 requests, shall be collected, enforced and received by Guarantor, in  trust,
 as trustee  for Lender and shall  be paid over to  Lender on account of  the
 Liabilities, but without reducing  or affecting in any manner the  liability
 of  Guarantor  under the  other  provisions of  this  Guaranty.   Lender  is
 authorized and empowered, but  not obligated, in its discretion, (a) in  the
 name of Guarantor, to  collect and enforce, and to submit claims in  respect
 of,  any indebtedness  of Borrower  to Guarantor  and to  apply any  amounts
 received thereon  to the Liabilities,  and (b) to  require Guarantor (i)  to
 collect and  enforce, and to submit claims  in respect of, any  indebtedness
 of  Borrower to Guarantor,  and (ii)  to pay  any amounts  received on  such
 indebtedness to Lender for application to the Liabilities.
<PAGE>
          10.    Subrogation.  Guarantor will  not-exercise any  rights.which
 it may acquire by way of subrogation under this Continuing Guaranty, by  any
 payment hereunder or otherwise, until all of the Liabilities have been  paid
 in full, in cash, and Lender shall have no further obligations to  Borrowers
 under the Loan  Documents or  otherwise.   If any  amount shall  be paid  to
 Guarantor on account  of such  subrogation rights  at any  other time,  such
 amount shall  be held  in trust  for  the benefit  of  Lender and  shall  be
 forthwith paid to  Lender to  be credited  and applied  to the  Liabilities,
 whether matured or unmatured,  in such manner as  Lender shall determine  in
 its sole discretion.

            11.       Assignment of  Lender's Right.   Lender may, from  time
 to time, without notice to Guarantor, assign  or transfer any or all of  the
 Liabilities or any interest therein and, notwithstanding any such assignment
 or transfer of,  the liabilities or  any subsequent  assignment or  transfer
 thereof, the Liabilities shall be and remain the Liabilities for the purpose
 of this  Continuing  Guaranty.   Each  and every  immediate  and  successive
 assignee or transferee of any of the Liabilities or of any interest  therein
 shall, to  the  extent of  such  party's  interest in  the  Liabilities,  be
 entitled to the benefits of this  Continuing Guaranty to the same extent  as
 if such assignee or  transferee were Lender;  provided, however that  unless
 Lender shall otherwise consent in writing,  Lender shall have an  unimpaired
 right, prior and  superior to that  of any such  assignee or transferee,  to
 enforce this Continuing  Guaranty for  its own benefit  as to  those of  the
 Liabilities which Lender has not assigned or transferred

          12.         Indulgences Not  Waivers. No delay  in the exercise  of
 any right or  remedy shall operate  as a waiver  thereof, and  no single  or
 partial exercise by Lender  of any right or  remedy shall preclude other  or
 further exercise thereof or the exercise  of any other right or remedy;  nor
 shall any modification or waiver of any of the provisions of this Continuing
 Guaranty be binding upon Lender, except as expressly set forth in a  writing
 duly signed  and  delivered  by  Lender.   No  action  of  Lender  permitted
 hereunder shall in  any way affect  or impair the  rights of  Lender or  the
 obligations of Guarantor under this Continuing Guaranty.

            13.       Financial Condition  of Borrower. Guarantor  represents
 and warrants that it is fully aware of the financial condition of  Borrower,
 and Guarantor delivers this  Continuing Guaranty based  solely upon its  own
 independent investigation of Borrower's financial  condition and in no  part
 upon any  representation  or  statement  of  Lender  with  respect  thereto,
 Guarantor further represents and  warrants that it is  in a position to  and
 hereby  does  assume  full  responsibility  for  obtaining  such  additional
 information concerning Borrowers financial  condition as Guarantor may  deem
 material to its obligations  hereunder, and Guarantor  is not relying  upon,
 nor expecting Lender to  furnish it any  information in Lender's  possession
 concerning Borrower's financial  condition or  concerning any  circumstances
 bearing on  the  existence  or  creation,  or  the  risk  of  nonpayment  or
 nonperformance of the Liabilities.

              Guarantor  hereby waives  any duty  on the  part of  Lender  to
 disclose to Guarantor any facts it may now or hereafter know about Borrower,
 regardless of  whether Lender  has reason  to believe  that any  such  facts
 materially increase the risk beyond that  which Guarantor intends to  assume
 or has reason to believe that such facts are unknown to Guarantor.
<PAGE>
              Guarantor hereby  knowingly  accepts  the full  range  of  risk
 encompassed  within  a contract  of  "Continuing Guaranty"  which  includes,
 without  limitation,  the  possibility  that  Borrower  will  contract   for
 additional indebtedness  for which Guarantor may  be liable hereunder  after
 Borrower's financial condition or ability to pay its lawful debts when  they
 fall due has deteriorated.

            14.          Representations    and     Warranties.     Guarantor
 represents and warrants to  Lender that each of the following statements  is
 accurate and complete as of the date of this Continuing Guaranty:

          executed and delivered by Guarantor and constitutes a legal,  valid
          and binding obligation of Guarantor, enforceable against  Guarantor
          in accordance  with its  terms, except  as limited  by  bankruptcy,
          insolvency or  other laws  of general  application relating  to  or
          affecting the enforcement of creditors' rights generally;

                    b.        the  execution,  delivery  and  performance  of
          this Continuing Guaranty do not (i)  violate any provisions of  law
          or any order of  any court or other  agency of government (each,  a
          "Requirement  of  Law"),  (ii)  contravene  any  provision  of  any
          material contract or agreement to which Guarantor is a party or  by
          which  Guarantor  or   Guarantor's  assets  are   bound  (each,   a
          "Contractual Obligation"),  or  (iii)  result in  the  creation  or
          imposition of any lien,  charge or encumbrance  of any nature  upon
          any property, asset or revenue of Guarantor;

                    c.        all    consents,    approvals,    orders    and
          authorizations of,  and  registrations,  declarations  and  filings
          with, any  governmental  agency or  authority  or other  person  or
          entity  (including,   without  limitation,   the  shareholders   or
          partners of any entity), if any, which are required to be  obtained
          in connection with  the execution and  delivery of this  Continuing
          Guaranty or the  performance of  Guarantor's obligations  hereunder
          have been obtained, and each is in full force and effect.

                    d.        Guarantor has paid all taxes and other  charges
          imposed by any governmental agency or authority due and payable  by
          Guarantor other  than  those which  are  being challenged  in  good
          faith by appropriate proceedings;

                    e.       Guarantor is not in violation of any Requirement
          of  Law or  Contractual Obligation  other  than any  violation  the
          consequences of which could  not have a material adverse effect  on
          Guarantor's  ability  to  perform  its  obligations  hereunder   (a
          "Material Adverse Effect"); and

                     f.    no action, proceeding, investigation or litigation
          is pending  or, to  the knowledge  of Grantor,  overtly  threatened
          against  Guarantor by  any person  or  entity which,  if  adversely
          determined, could have a Material Adverse Effect.

            15.       Guarantor Financial Information. Guarantor will provide
 Lender in  writing such  financial  and other  information  with  respect to
 Guarantor's  assets  and liabilities  as  Lender  shall  reasonably  request
 from time to time, in form satisfactory to Lender.

            16.       Binding  Upon Successors:  Death  of  Guarantor    This
 Continuing  Guaranty  shall  be  binding  upon  Guarantor  and   Guarantor's
 successors and assigns  and shall  inure to the  benefit of  Lender and  its

 contained in this Continuing Guaranty or  in any other document,  instrument
 or agreement between  or among  any of  Lender, Borrower,  Guarantor or  any
 third party, the obligations  of Guarantor with  respect to the  Liabilities

 the complete understanding of the parties hereto with respect to the subject
 matter herein.  Guarantor  acknowledges that Guarantor  is not relying  upon
 any statements or representations of Lender not contained in this Continuing
