 all rights  and  remedies  accorded by  applicable  law  to  indemnitors  or
 guarantors, except  any  rights  of  subrogation  which  Company  may  have,
 provided  that  the  indemnity  provided  for  hereunder  shall  neither  be
 contingent upon the existence of any such rights of subrogation nor  subject
 to any claims  or defenses whatsoever  which may be  asserted in  connection
 with the enforcement  or attempted  enforcement of  such subrogation  rights
 including, without limitation, any claim  that such subrogation rights  were
 abrogated  by  any  acts  of   Indemnitee  or  other  Indemnified   Parties.
 Notwithstanding anything to  the contrary contained  herein, Company  hereby
 agrees to postpone the exercise of any rights of subrogation with respect to
 any collateral securing  the Transaction  until the  Transaction shall  have

 any such privilege, power or right.

 ACTS OR OMISSIONS OF ANY INDEMNIFIED PARTIES IN CONNECTION THEREWITH.

            4.4  REMEDIES. In addition  to and without limiting  Indemnitee's

 way resolve or minimize the impact of, or otherwise deal with, any Hazardous
 Materials on or affecting the Property.

 liability under  this Agreement  is unrelated  to  and independent  of,  the
 amount of any loss that  Indemnitee may suffer by  reason of the failure  of
 Company to  satisfy in  full its  obligations  under the  other  Transaction
 Documents, and shall  not be determined  by reference to  the amount of  any
 Transaction loss. No amount paid to  any Indemnified Party pursuant to  this
 Agreement shall be considered to be paid on account of or in satisfaction of
 Company's  obligations  under  the   other  Transaction  Documents  or   any
 deficiency or  loss suffered  by  Indemnitee by  reason  of the  failure  of
 Company to  satisfy in  full its  obligations  under the  other  Transaction
 Documents. The enforcement of this Agreement by any Indemnified Party  shall
 not be construed  as an  indirect attempt  to recover  any such  Transaction
 loss. Company acknowledges that they may have liability under this Agreement
 even  if  Company  satisfies  in  full  its  obligations  under  the   other
 Transaction Documents by reason of a full credit bid at any foreclosure sale
 under any  other Transaction  Document, and  that  the amount  of  Company's
 liability hereunder could exceed the entire  amount paid by Company for  the
 Property.

            4.6  SURVIVAL. The indemnity  in this Section  is intended to  be
 operable under 42 U.S.C. 9607(e)(1), and any successor section thereof,  and
 shall survive the  foreclosure, release or  reconveyance of any  Transaction
 Document, whether  by  payment  of the  obligations  under  the  Transaction
 Documents or any deed-in-lieu of foreclosure of the Property.

                                      D. Ronald Allen, PresidentExhibit 4.23

                          FINOVA CAPITAL CORPORATION
                            FINOVA BUSINESS CREDIT

                         CONTINUING PERSONAL 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. D. RONALD ALLEN ("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 Personal 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;

                 b.         the  power  or  authority  or  lack  thereof   of
       Borrower to incur the Liabilities;
<PAGE>
                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;

                 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;
<PAGE>
                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 Guarantors 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

           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.
<PAGE>
           11.        Assignment of Lender's  Rights. 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.
<PAGE>
           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

           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:

                a.        this  Continuing Guaranty  has been  duly  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;
<PAGE>
                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
 successors and assigns. This Continuing Guaranty  shall not terminate or  be
 revoked upon the death of Guarantor, notwithstanding any knowledge by Lender
 of Guarantor's death.

           All references  herein to Borrower shall be deemed to include  its
 successors and  assigns, and  all references  herein to  Guarantor shall  be
 deemed to include Guarantor and Guarantor's successors and assigns or,  upon
 the death  of  Guarantor, the  duly  appointed representative,  executor  or
 administrator of Guarantor's estate.

           In   addition  and  notwithstanding   anything  to  the   contrary
 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
 shall be joint  and several  with any  other person  or entity  that now  or
 hereafter executes a guaranty of any  of the Liabilities separate from  this
 Continuing Guaranty.

           17.        Notices. All notices required or permitted to be  given

 Guaranty has  been delivered  and  shall be  governed  by and  construed  in

 provisions) of the State of Arizona.

      this  Continuing  Guaranty in  any  court  other than  one  located  in
      Maricopa County, Arizona.

 action or proceeding against Guarantor or its property in the courts of  any
 other jurisdiction.  Wherever possible  each  provision of  this  Continuing
 Guaranty shall be interpreted as to be effective and valid under  applicable
 law, but if any provision of this Continuing Guaranty shall be prohibited by
