and (b) in the maximum  aggregate  principal  amount of $2,750,000 (the "Maximum

aggregate  principal  amount of $2,750,000,  Viking shall have the right, at any
time on or prior to the date that is two (2) weeks after the First Closing Date,
to issue  Promissory  Notes to one or more  Investors in an amount not to exceed
the  Maximum  Aggregate  Principal  Amount,  provided  that any such  additional

     be  evidenced by a Promissory  Note and secured by a Second  Priority  Lien
     against all of the Collateral as set forth in the Security Instruments.  On
     the First Closing Date,  Viking shall  execute a Security  Agreement  which
     shall grant to each Investor and  Collateral  Agent a security  interest in
     the  Collateral  in  order  to  secure  prompt  repayment  of any  and  all
     Obligations  owed by Viking to each  Investor and in order to secure prompt
     performance  by  Viking of its  covenants  and  obligations  under the Loan
     Documents.  The  Investors  agree to enter into a  customary  subordination
     agreement as may reasonably be requested by Silicon Valley Bank relating to
     the  subordination  of  Investor's  loan to the rights and  preferences  of
     Silicon Valley Bank pursuant to the SVB Loan Agreement.

          2.3 Loan  Closing  Fee. On the  applicable  Closing Date for each such
     Investor, a total of two percent (2%) of the Loan from an Investor shall be

     Closing Date, Viking shall receive  ninety-eight percent (98%) of the total
     Loan  proceeds and each of the  Investors  shall retain two percent (2%) of
     such Investor's Loan as a Closing Fee.

          2.4 Accredited  Investors  Only. The Promissory  Notes will be offered
     and sold to only a limited number of selected sophisticated Investors, each
     of whom  Viking  has  reasonable  grounds  to  believe  and  does  believe,
     immediately before making an offer,  qualifies as an "accredited investor,"
     as that term is defined in Rule 501 of Regulation D  promulgated  under the
     Securities  Act of 1933, as amended (the  "Securities  Act"),  and has such
     knowledge  and  experience  of  financial  and  business  matters that such
     prospective  purchaser  is  capable of  evaluating  the merits and risks of
     investing in the Promissory Notes.

     3.  Deliveries at Closing.  Subject to the terms and  conditions  set forth
herein, the closings of the transactions contemplated herein (each, a "Closing")
shall take place at the offices of Latham & Watkins LLP, 633 West Fifth  Street,

          Expenses  may be  deducted  or  withheld  from the amount paid by Lead
          Lender to  Viking in  connection  with the Lead  Lender's  Loan at the
          First  Closing;  provided,  however,  that Lead Lender  shall  provide
          Viking with the  aggregate  amount of  Transaction  Expenses as of the
          First  Closing  Date within  thirty (30) days after the First  Closing
          Date and to the extent such amount is less than the  estimated  amount
          deducted at the Closing on the First  Closing  Date,  such  difference
          shall be  promptly  paid by Lead  Lender to Viking,  and to the extent
          such  amount is greater  than the  estimated  amount  deducted  at the
          Closing on the First Closing Date, such  difference  shall be promptly
          paid by Viking to Lead Lender;

               3.1.9 Completed Small Business  Administration  ("SBA") forms No.
          480 (Size Status  Declaration),  No. 652 (Assurance of Compliance) and
          No. 1031 (Portfolio Financing Report, Parts A and B);

               3.1.10 A certificate, dated as of the Closing Date, signed by the
          Chief Executive Officer and President of Viking,  certifying as to the
          use of proceeds from the issuance of the Promissory Note.

               3.1.11 An  opinion  from  Cohne,  Rappaport  & Segal,  counsel to
          Viking,  dated as of the Closing Date and addressed to Lead Lender, in
          the form acceptable to Lead Lender.

               3.1.12  Such  other  documents   relating  to  the   transactions
          contemplated  by this  Agreement  as Lead  Lender or its  counsel  may
          reasonably request.

          3.2 Deliveries by Investor at Closing. The obligations of Viking under
     this Agreement are subject to the fulfillment,  on or before the Closing of
     each of the following conditions,  unless otherwise waived. At the Closing,
     each Investor will have delivered to Viking or its counsel:

               3.2.1.  A wire transfer to the account  listed in Schedule  3.2.1
          hereto in an amount  equal to such  Investor's  Loan less the  Closing
          Fees (and in the case of Lead Lender, less the Transaction  Expenses);
          and

                                       9



               3.2.2 This Agreement, signed by a duly authorized officer of each
          Investor,  or if Investor is an  individual,  by such Investor (or, if
          after  the  First  Closing   Date,  an  Addendum   Agreement  to  this
          Agreement);

               3.2.3  The  Registration  Rights  Agreement,  signed  by  a  duly
          authorized officer of each Investor,  or if Investor is an individual,
          by such  Investor  (or,  if after the Closing  Date,  a Joinder to the
          Registration Rights Agreement); and

               3.2.4 The Security Agreement, signed by a duly authorized officer
          of each Investor, or if Investor is an individual, by such Investor.

     4. Note Conversion Rights.  Each Investor shall have the right from time to
time,  and at any  time on or  prior  to the  Maturity  Date of such  Investor's
Promissory Note, to convert all or any part of the amount then outstanding under
such  Investor's  Promissory Note into fully paid and  non-assessable  shares of
Common Stock, at the Conversion  Price.  Notwithstanding  the foregoing,  in the
event that any sums due under a  Promissory  Note are not repaid on the Maturity
Date, in lieu of accepting  repayment of the  Promissory  Note from Viking,  the
Investor  will have the option at any time and from time to time to convert  the
entirety of the debt then  outstanding,  plus any  accrued  but unpaid  interest
thereon, under such Promissory Note into fully paid and non-assessable shares of
Common Stock, at the Default Conversion Price.

          4.1.  Conversion  Procedure.  To convert a Promissory Note into Common
     Stock,  the holder thereof shall  surrender to Viking the Promissory  Note,
     and give written  notice  ("Conversion  Notice") to Viking that such holder
     elects to convert  all or a portion  of such  Promissory  Note into  Common
     Stock. The Conversion Notice shall specify (i) the amount of the Promissory
     Note to be converted  and the name or names in which such holder wishes the
     certificate  or  certificates  for  Common  Stock  and any  portion  of the
     Promissory Note not to be so converted to be issued and (ii) the address to
     which such holder wishes delivery to be made of such new certificates (and,
     if applicable, a replacement Promissory Note reflecting the portion of such
     Promissory  Note that shall not have been converted) to be issued upon such
     conversion.  As promptly as practicable  on or after the  conversion  date,
     Viking shall issue and shall deliver a certificate or certificates  for the
     number of full shares of Common Stock  issuable upon  conversion,  together
     with payment in lieu of any fractional share, as hereinafter  provided,  to
     the person or persons entitled to receive the same. In the event that there
     shall have been  surrendered a Promissory  Note only part of which is to be
     converted,  Viking shall issue and deliver to such holder or such  holder's
     designee a new Promissory Note  representing that portion of the Promissory
     Note which shall not have been converted.

          4.2.  Mandatory  Conversion  Rights.  Viking  shall  have the right to
     require an Investor to convert all or a portion of such  Investor's Loan at
     the Conversion Price in the event that:

               (i) no Event of Default  exists or is  continuing  at the time of
          such mandatory conversion; and

               (ii) Viking has raised a minimum of  $3,000,000  in public and/or
          private equity offerings on or prior to the one-year  anniversary date

                                       10



          of the Closing at an average  price equal to or greater than $0.30 per
          share of Common  Stock.  For  purposes  of this  Section  4.2,  equity
          attributed to the issuance or conversion  of the  Promissory  Notes or
          the Warrants shall not be included in the  calculation of such average
          price.

          4.3.  Procedure  for  Mandatory  Conversion.  In the event that Viking
     elects to cause the mandatory  conversion  of Promissory  Notes into Common
     Stock pursuant to Section 4.2 of this Agreement,  Viking shall give written
     notice of  mandatory  conversion  ("Mandatory  Conversion  Notice") to each
     Investor  instructing  the Investor to  surrender to Viking the  Promissory
     Note,  and give written  notice to each of the Investors that Viking elects
     to convert all or a portion of a holder's Promissory Note into Common Stock
     pursuant to Section 4.2 of this Agreement. Such Mandatory Conversion Notice
     shall specify the amount of the  Promissory  Note to be converted.  If less
     than all of the entire unpaid  balance of all of the  Promissory  Notes are
     converted in full, then in such event,  the mandatory  conversion  shall be
     effected on a pro rata basis for all Investors.  Immediately  upon Viking's
     mailing of a Mandatory  Conversion  Notice,  the Promissory Notes shall, to
     the  extent of the  amount to be  converted  as set forth in the  Mandatory
     Conversion  Notice,  be deemed to be  converted  into  Common  Stock and no
     interest shall thereafter accrue on the amount to be converted as set forth
     in the  Mandatory  Conversion  Notice.  As  promptly as  practicable  after
     Viking's receipt of an Investor's  Promissory Note,  Viking shall issue and
     shall deliver a certificate or  certificates  for the number of full shares
     of  Common  Stock  issuable  upon  such  conversion,  together  with  a new
     Promissory  Note for the remaining  outstanding  principal  balance of each
     Promissory  Note  if less  than  the  entire  original  Promissory  Note is
     converted.

     5. Warrants.  As additional  consideration for an Investor making a Loan to
Viking pursuant to this Agreement, Viking shall issue each Investor a Warrant to
purchase  shares of Viking's  Common Stock.  Each Warrant is exercisable at $.40
per share, subject to adjustment pursuant to the terms of such Warrant, and each
Warrant  shall be for a term of forty-two  (42) months from the date hereof.  An
Investor shall be issued a Warrant to purchase one (1) share of Common Stock for
each four (4) shares  issuable  upon  conversion of the  Promissory  Note at the
Conversion  Price,  subject to adjustment  pursuant to the terms of the Warrant.
For example,  if an Investor loans $500,000 to Viking  hereunder,  such Investor
shall be issued Warrants to purchase 625,000 shares of Common Stock.

     6.  Registration  Rights.  The Common Stock issuable upon the conversion of
the Promissory Notes and the Common Stock issuable upon exercise of the Warrants
shall be subject to a Registration  Rights  Agreement  substantially in the form
attached hereto as Exhibit "C."

     7.  Adjustments  to  Conversion  Price  and  Warrant  Exercise  Price.  The
Conversion Price and the Default Conversion Price in effect at any time and from
time to time shall be subject to adjustment from time to time upon the happening
of certain events as follows:

          7.1 New  Issuances.  If at any time after the issuance of a Promissory
     Note  and  prior to the  repayment  in full or  conversion  in full of such
     Promissory  Note,  Viking issues or sells (a "New  Issuance") any shares of
     common stock for a consideration  per share less than the Conversion  Price
     or  Default  Conversion  Price  in  effect  immediately  prior  to such New

                                       11



     Issuance,  then,  immediately upon such New Issuance,  the Conversion Price
     and the Default  Conversion Price, as applicable,  of the unpaid portion of
     the  Promissory  Note shall be reduced to an amount  equal to the price per
     share of common  stock  issued  in the New  Issuance.  If the New  Issuance
     involves the issuance of Convertible  Securities,  the Conversion Price and
     Default Conversion Price, as applicable,  shall be reduced to the effective
     price of the common stock  issuable  under such  Convertible  Securities if
     such  effective  price  is  less  than  the  Conversion  Price  or  Default
     Conversion Price, as applicable.

          7.2 Reorganization,  Reclassification,  Consolidation, Merger or Sale.
     If any  capital  reorganization,  reclassification  or any other  change of
     capital  stock of Viking,  or any  consolidation  or merger of Viking  with
     another Person,  or the sale or transfer of all or substantially all of its
     assets to another  Person  shall be effected in such a way that  holders of
     shares of Common Stock shall be entitled to receive  stock,  securities  or
     assets with  respect to or in exchange  for their  shares of Common  Stock,
     then  provision  shall be made by Viking,  in accordance  with this Section
     7.2,  whereby each holder of the Promissory Note shall  thereafter have the
     right  to  receive,  upon the  basis  and upon  the  terms  and  conditions
     specified herein and in addition to or in exchange for, as applicable,  the
     shares  of  Common  Stock  subject  to  the  Promissory  Note   immediately
     theretofore  receivable  upon  conversion  of such  Promissory  Note at the
     Conversion  Price  or  Default  Conversion  Price  (depending  on  which is
     applicable at the time of the actual  conversion of the  Promissory  Note),
     such securities or assets as would have been issued or payable with respect
     to or in exchange  for the  aggregate  shares of Common  Stock  immediately
     theretofore receivable upon conversion of the Promissory Note if conversion
     of  the   Promissory   Note  had   occurred   immediately   prior  to  such
     reorganization,  reclassification,  consolidation,  merger or sale.  Viking
     will not effect any such  consolidation,  merger,  sale,  transfer or lease
     unless prior to the  consummation  thereof the  successor  entity (if other
     than  Viking)  resulting  from such  consolidation  or merger or the entity
     purchasing  such  assets  shall  assume  by  written   instrument  (i)  the
     obligation to deliver to the holder of the Promissory  Note such securities
     or assets as, in accordance  with the foregoing  provisions,  the holder of
     the  Promissory  Note may be entitled  to receive  upon  conversion  of the
     Promissory  Note,  and (ii) all  other  obligations  of  Viking  under  the
     Promissory  Note. The provisions of this Section 7.2 shall  similarly apply
     to  successive  consolidations,  mergers,  exchanges,  sales,  transfers or
     leases.   In  the  event  that  in   connection   with  any  such   capital
     reorganization  or   reclassification,   consolidation,   merger,  sale  or
     transfer,  additional  shares of Common  Stock shall be issued in exchange,
     conversion, substitution or payment, in whole or in part, for a security of
     Viking other than Common Stock, any such issue shall be treated as an issue
     of Common Stock covered by the provisions of Section 7.2 hereof.

          7.3 Stock Dividends and Securities  Distributions.  If, at any time or
     from time to time after the date  hereof,  Viking shall  distribute  to the
     holders  of shares  of  Common  Stock  (i)  securities  (including  rights,
     warrants,  options or another form of  convertible  securities)  other than
     securities  of Viking,  (ii)  property,  other than  cash,  or (iii)  cash,
     without fair payment  therefor,  then, and in each such case, the holder of
     the  Promissory  Note,  upon  conversion  of  the  Promissory  Note  at the
     Conversion  Price  or  Default  Conversion  Price  (depending  on  which is
     applicable at the time of the actual  conversion of the  Promissory  Note),
     shall be entitled to receive such  securities,  property and cash which the
     holder of the Promissory Note would hold on the date of such conversion if,

                                       12



     on the date of the distribution, the holder of the Promissory Note had been
     the  holder of  record of the  shares  of  Common  Stock  issued  upon such
     conversion and, during the period from the date hereof to and including the
     date of such  conversion,  had retained such shares of Common Stock and the
     securities,  property and cash  receivable by the holder of the  Promissory
     Note during such period, subject,  however, to the holder of the Promissory
     Note agreeing to any  conditions to such  distribution  as were required of
     all  other  holders  of  shares of  Common  Stock in  connection  with such
     distribution.

          7.4 Other  Adjustments.  In addition to those adjustments set forth in
     Section 7.2 and Section 7.3, but without  duplication of the adjustments to
     be made under such Sections, if Viking:

               (i) makes a  distribution  on its  Common  Stock in shares of its
          Common Stock;

               (ii) subdivides or reclassifies its outstanding  shares of Common
          Stock into a greater number of shares;

               (iii) combines or reclassifies  its outstanding  shares of Common
          Stock into a smaller number of shares;

               (iv) makes a  distribution  on its Common  Stock in shares of its
          capital stock other than Common Stock; and/or

               (v) issues, by  reclassification  of its Common Stock, any shares
          of its capital stock;

          then the Conversion Price in effect  immediately  prior to such action
     (and the number and kind of capital stock  purchasable  upon  conversion of
     the Promissory  Note, upon the occurrence of any of the events described in
     (iv) and (v) above),  shall be adjusted so that the holder of a  Promissory
     Note upon  conversion  thereof  shall be  entitled to receive the number of
     shares of Common Stock (and such other  securities)  that the holder of the
     Promissory Note would have owned or have been entitled to receive after the
     happening of any of the events described above had the Promissory Note been
     converted  immediately  prior to the  happening of such event or any record
     date with respect thereto,  and the Default  Conversion  Price  immediately
     prior to such action shall be adjusted proportionately to the adjustment of
     the Conversion Price. An adjustment made pursuant to this Section 7.4 shall
     become  effective  immediately  after  the  record  date  in the  case of a
     dividend or distribution and shall become effective  immediately  after the
     effective date in the case of a subdivision,  combination or issuance.  If,
     as a result of an adjustment  made pursuant to this Section 7.4, the holder
     of the Promissory Note thereafter  surrendered for conversion  shall become
     entitled to receive  shares of two (2) or more classes of capital  stock or
     shares of Common Stock and any other class of capital stock of Viking,  the
     Board of  Directors in good faith shall  determine  the  allocation  of the
     adjusted  Conversion  Price and Default  Conversion  Price between or among
     shares of such classes of capital  stock or shares of Common Stock and such
     other class of capital stock.

          The adjustment to the Conversion  Price and Default  Conversion  Price
     (and number and kind of capital stock  purchasable  upon  conversion of the

                                       13



     Promissory  Note) described in this Section 7.4 shall be made each time any
     event listed in paragraphs (i) through (v) of this Section 7.4 occurs.

               (vi) In the event that at any time,  as a result of an adjustment
          made pursuant to this Section 7.4, the holder of the  Promissory  Note
          thereafter  shall  become  entitled  to receive  any shares of Viking,
          other than Common Stock,  thereafter the Conversion  Price and Default
          Conversion Price shall be subject to adjustment from time to time in a
          manner  and on  terms  as  nearly  equivalent  as  practicable  to the
          provisions  with respect to the Common Stock contained in this Section
          7.4.

          7.5 Notice of Adjustment.  Upon any adjustment of the Conversion Price
     or Default Conversion Price, then and in each such case Viking, at its sole
     expense,  shall give written  notice thereof (i) by certified or registered
     mail,  postage  prepaid,  (ii) by a  nationally  known  overnight  delivery
     service,  or  (iii)  delivered  by hand,  addressed  to the  holder  of the
     Promissory  Note at his  address  as shown on the  books of  Viking,  which
     notice shall state the conversion  price resulting from such adjustment and
     adjusted  number  of  shares of Common  Stock or other  capital  stock,  as
     applicable, issuable upon exercise of the Promissory Note, setting forth in
     reasonable detail the method upon which such calculation is based.

          7.6 Warrant  Adjustments.  The Warrant  attached hereto as Exhibit "B"
     contains a provision  providing for the  reduction of the Warrant  exercise
     price upon a New Issuance at less than the  Conversion  Price and for other
     adjustments to the number of Warrant shares and the warrant exercise price.

     8. [Reserved.]

     9. Remedies.  Upon the occurrence of an Event of Default and the expiration
of any notice and cure period  provided for under the Loan  Documents  (if any),
the  entire  indebtedness  owed to the  Investor  shall,  at the  option  of the
Investor,  immediately  become  due and  payable  without  presentment,  demand,
protest,  or other  notice of any kind,  all of which  are  expressly  waived by
Viking;  provided  that the  occurrence  of an Event of  Default as set forth in
Section  6(iv) and Section  6(v) of the  Promissory  Note shall make all sums of
principal and interest then remaining unpaid and all other amounts payable under
the Loan Documents due and payable, all without demand,  presentment,  notice or
protest,  all of which hereby are expressly waived,  and will permit Investor to
exercise any other right  available to it at law or in equity,  all which rights
and powers may be  exercised  cumulatively.  The Investor may proceed with every
remedy available at law or in equity or provided for in this Agreement or in any
of the Loan Documents,  and all expenses  incurred by the Investor in connection
with any remedy  shall be deemed  indebtedness  of Viking to the  Investor.  The
Collateral  Agent,  on behalf of the  Investor,  may apply the proceeds from any
Collateral or from any other source  against any part of the Loans as and in any
order the Collateral Agent sees fit but on a pro rata basis to each Investor.

     No delay or failure of an Investor  in the  exercise of any right or remedy
provided for under this  Agreement or under any of the Loan  Documents  shall be
deemed a waiver of such right by the Investor.  No exercise or partial  exercise
or  waiver  of any  right or  remedy  shall be  deemed a waiver  of any  further
exercise  of such  right or  remedy or of any  other  right or  remedy  that the
Investor  may have  under  this  Agreement  or under any of the Loan  Documents.

                                       14



Enforcement  of any of the  Investor's  rights as to any  security  for the Loan
shall not affect  the  Investor's  right to  enforce  payment of the Loan and to
recover  judgment  for any  portion  thereof  remaining  unpaid.  The rights and
remedies  set  forth  in this  Agreement  and in any of the Loan  Documents  are
cumulative  and not  exclusive of any other right or remedy that an Investor may
have.

     10. Lead Lender.

          10.1. Board of Directors Matters.  Until the Loans are repaid in full,
     Lead Lender shall have the option of designating one person to serve on the
     Board of Directors of Viking ("Lead Lender  Director")  and/or one observer
     (the  "Observer")  to attend  meetings of the Board of Directors of Viking.
     Viking shall  reimburse  the  reasonable  travel costs and expenses of such
     Lead Lender Director and Observer incurred in attending any Viking Board of
     Directors  meetings or committee  meetings.  In  addition,  any Lead Lender
     Director shall be entitled to such other  compensation or benefits,  Viking
     makes available to its other outside  directors.  If Lead Lender designates
     an Observer to Viking's Board of Directors, then:

               (i) such Observer shall have the right to attend, as an observer,
          all  meetings  of  Viking's  Board of  Directors  and all  meetings of
          committees of Viking Board of Directors;

               (ii)  receive   copies  of  all  written   documents   and  other
          information (including copies of meeting minutes) provided to Viking's
          Board members in connection  with Board  Meetings and Board  committee
          meetings at the same time such materials and  information are provided
          to Viking's Board members;

               (iii) if Viking  proposes to take any action  through the written
          consent of its Board of  Directors,  then Viking  shall  provide  such
          Observer with a written notice of such proposed Board actions prior to
          the effective date thereof, describing in reasonable detail the nature
          and substance of such action.

          10.2. Financial Information.  Viking shall furnish to Lead Lender such
     financial  information as may be reasonably  requested by Lead Lender. Such
     financial information shall include, but not be limited to:

               (i) audited financial  statements within one hundred twenty (120)
          days of Viking's fiscal year end;

               (ii) internally prepared financial  statements within thirty (30)
          days of each calendar month end; and

               (iii) an annual  budget  for the  upcoming  fiscal  year by month
          within  thirty (30) days of fiscal  year end.  All  financial  reports
          should include a balance sheet, income statement and statement of cash
          flows  prepared in accordance  with GAAP,  accompanied by a management
          discussion and analysis of the appropriate reporting period.

                                       15



     11.  Representations  and Warranties of Viking.  Viking makes the following
representations  and  warranties to each  Investor,  which  representations  and
warranties  shall be true and  correct as of the date  hereof and for so long as
any portion of any Promissory Note remains outstanding:

          11.1. Existence; Qualification; No Subsidiary. Viking is a corporation
     duly incorporated,  validly existing and in good standing under the laws of
     the State of Nevada,  and has full corporate power and authority to conduct
     its business and own and operate its business as now conducted and operated
     and as proposed to be  conducted.  Viking is  licensed  or  qualified  as a
     foreign  corporation and is in good standing in each jurisdiction  where it

     agreements providing for the payment of any royalties based on revenues (or
     a specific  revenue  stream)  of Viking.  There is no default or event that

          Safety  Requirements,  nor has  Viking  released  or waived  any third
          party,  either  expressly or by operation of law, from any  liability,
          obligation or responsibility  relating to any Environmental and Safety
          Requirements.

               (f) To the  knowledge of Viking,  no facts,  events or conditions
          relating to the past or present  facilities,  properties or operations
          of Viking will prevent,  hinder or limit  continued  compliance in all
          material  respects with  Environmental and Safety  Requirements,  give
          rise to any investigatory, remedial or corrective obligations pursuant
          to Environmental  and Safety  Requirements,  or give rise to any other
          material   liabilities   (whether   accrued,   absolute,   contingent,
          unliquidated  or  otherwise)  pursuant  to  Environmental  and  Safety
          Requirements,  including any relating to onsite or offsite releases or
          threatened  releases of  hazardous  materials,  substances  or wastes,
          personal injury, property damage or natural resources damage.

               (g)  Neither  this   Agreement  nor  the   consummation   of  the
          transaction  that is the subject of this  Agreement will result in any
          obligations for site  investigation or cleanup,  or notification to or
          consent of government  agencies or third  parties,  pursuant to any of
          the  so-called   "transaction-triggered"   or  "responsible   property
          transfer" Environmental and Safety Requirements.

               (h)  Viking  has,  neither  expressly  nor by  operation  of law,
          assumed or undertaken  any  liability,  including any  obligation  for
          corrective  or  remedial  action,  of any  other  Person  relating  to
          Environmental and Safety Requirements.

               (i) Viking has  provided  each  Investor  with true,  correct and
          complete  copies  of  all   environmental   reports,   assessments  or
          investigations  and all parts  thereof  (including  any drafts of such
          items) regarding any property  currently or formerly owned,  leased or
          operated by such Viking.


          11.16 Employee Benefits and Plans.


               (a) Schedule 11.16(a) sets forth a true and complete list of each
          "employee  benefit plan" as defined in Section 3(3) of ERISA,  and any
          other plan,  policy,  program  practice,  agreement,  understanding or
          arrangement (whether written or oral) providing  compensation or other
          benefits  to any  current or former  director,  officer,  employee  or
          consultant (or to any dependent or  beneficiary  thereof) of Viking or
          any ERISA Affiliates (as defined below), which are now, or were within
          the past six years, maintained,  sponsored or contributed to by Viking
          or any ERISA  Affiliate,  or under which Viking or any ERISA Affiliate
          has  any  obligation  or  liability,  whether  actual  or  contingent,
          including,   without  limitation,   all  incentive,   bonus,  deferred
          compensation, vacation, holiday, cafeteria, medical, disability, stock
          purchase, stock option, stock appreciation,  phantom stock, restricted
          stock or other stock-based  compensation  plans,  policies,  programs,
          practices or arrangements (each a "Viking Benefit Plan"). For purposes
          of this Agreement, "ERISA Affiliate" shall mean any entity (whether or
          not  incorporated)  other than Viking that is considered  under common
          control and treated as one employer under Section 414(b),  (c), (m) or
          (o) of the  Internal  Revenue Code of 1986,  as amended (the  "Code").
          Viking does not have, and to the knowledge of Viking, no other Person,

                                       22



          has any express or implied commitment,  whether legally enforceable or
          not, to modify,  change or terminate any Viking  Benefit  Plan,  other
          than with respect to a modification, change or termination required by
          ERISA,  the Code or any other  applicable law or governmental  rule or
          regulation.

               (b)  Each  Viking  Benefit  Plan  has  been  administered  in all
          material  respects  in  accordance  with its terms and all  applicable
          laws,  including ERISA and the Code, and contributions  required to be
          made under the terms of any of the Viking Benefit Plans as of the date
          of this  Agreement have been timely made or, if not yet due, have been
          properly reflected on the most recent consolidated balance sheet filed
          or  incorporated  by  reference  in  Parent's   audited   consolidated
          financial statements prior to the date of this Agreement. With respect
          to the  Viking  Benefit  Plans,  no event  has  occurred  and,  to the
          knowledge of Viking, there exists no condition or set of circumstances
          in  connection  with which  Viking  could be  subject to any  material
          liability (other than for routine benefit liabilities) under the terms
          of, or with respect to, such Viking Benefit Plans,  ERISA, the Code or
          any other applicable law or governmental rule or regulation.

               (c) Except as  disclosed  on Schedule  11.16(c):  (i) each Viking
          Benefit  Plan which is  intended  to  qualify  under  Section  401(a),
          Section 401(k),  Section 401(m) or Section  4975(e)(6) of the Code has
          received  a  favorable  determination  letter  from  the IRS as to its
          qualified  status,  and each trust  established in connection with any
          Viking Benefit Plan which is intended to be exempt from federal income
          taxation  under  Section  501(a)  of the  Code  is so  exempt,  and to
          Viking's knowledge no fact or event has occurred that could reasonably
          be  expected  to  adversely  affect the  qualified  status of any such
          Viking  Benefit Plan or the exempt  status of any such trust;  (ii) to
          Viking's  knowledge there has been no prohibited  transaction  (within
          the  meaning of Section  406 of ERISA or Section  4975 of the Code and
          other  than  a  transaction  that  is  exempt  under  a  statutory  or
          administrative exemption) with respect to any Viking Benefit Plan that
          could result in material  liability to Viking or any ERISA  Affiliate;
          (iii) no suit, administrative  proceeding,  action or other litigation
          has been brought, or to the knowledge of Viking is threatened, against
          or with respect to any such Viking  Benefit Plan,  including any audit
          or inquiry by the IRS or United States Department of Labor (other than
          routine  benefits  claims);  (iv) none of the  assets of Viking or any
          ERISA  Affiliate  is, or may  reasonably  be expected  to become,  the
          subject of any lien arising under ERISA or Section 412(n) of the Code;
          (v) neither Viking nor any ERISA Affiliate has any material  liability
          under ERISA  Section 502;  (vi) all tax,  annual  reporting  and other
          governmental  filings  required by ERISA and the Code have been timely
          filed with the  appropriate  governmental  entity with respect to each
          Viking Benefit Plan; (vii) all  contributions and payments to or under
          each Viking  Benefit Plan which can  appropriately  be deducted  under
          either  Code  Section  162 or 404 are,  to the  knowledge  of  Viking,
          deductible;  and (viii) no excise tax could be imposed upon any Viking
          under Chapter 43 of the Code.

               (d) No Viking Benefit Plan is a "multiemployer  plan" (as defined
          in Section 3(37) or 4001(a)(3) of ERISA) (a  "Multiemployer  Plan") or
          is  subject  to  Title IV of ERISA or  Section  412 of the  Code,  and
          neither Viking nor any ERISA Affiliate has sponsored or contributed to
          or been  required  to  contribute  to a  Multiemployer  Plan or  other
          pension  plan  subject to Title IV of ERISA or Section 412 of the Code
          (a "Pension Plan").

                                       23



               (e) Except as set forth on  Schedule  11.16(e)  or as required by
          applicable  law, no Viking  Benefit Plan provides any of the following
          retiree or post-employment benefits to any person: medical, disability
          or life  insurance  benefits.  No Viking  Benefit  Plan is a voluntary
          employee  benefit  association  under  Section  501(a)(9) of the Code.
          Viking  and each of its  ERISA  Affiliates  are in  compliance  in all
          material  respects with (i) the requirements of the applicable  health
          care  continuation and notice  provisions of the Consolidated  Omnibus
          Budget  Reconciliation  Act of 1985, as amended,  and the  regulations
          (including proposed regulations)  thereunder and any similar state law
          and  (ii)  the  applicable   requirements  of  the  Health   Insurance
          Portability  and  Accountability  Act of  1996,  as  amended,  and the
          regulations thereunder.

               (f) Viking does not maintain,  sponsor,  contribute to or has any
          liability  with  respect  to any  employee  benefit  plan  program  or
          arrangement  that  provides  benefits to  non-resident  aliens with no
          United States source income outside of the United States.


          11.17 Taxes. Viking has filed all tax returns it was required to file,
     and has paid all taxes  shown on those tax  returns  as owing.  Viking  has
     withheld  and paid all taxes  required  to have been  withheld  and paid in
     connection  with  amounts  paid  or  owing  to  any  employee,  independent
     contractor,  creditor,  stockholder,  or  other  third  party.  There is no
     dispute or claim concerning any tax liability of Viking, either (i) claimed
     or raised by any  authority in writing or (ii) to the  knowledge of Viking,
     claimed or raised by any agent of such authority.

          11.18. Small Business Matters.

               11.18.1  Viking  acknowledges  that Lead  Lender  is a  federally
          licensed  SBIC  under  the  SBIC  Act.   Viking,   together  with  its
          "affiliates" (as that term is defined in 13 C.F.R.  Section  121.103),
          is  a  "small  business  concern"  within  the  meaning  of  the  SBIC
          Regulations,  including 13 C.F.R. Section 121.103. After giving effect
          to the  transactions  contemplated by the Loan Documents,  Viking will
          have 500 or fewer  full-time  equivalent  employees.  The  information
          regarding  Viking and its  affiliates  set forth in the SBA forms Nos.
          480, 652 and 1031  delivered at the Closing is accurate and  complete.
          Copies of such forms have been  completed  and  executed by Viking and
          delivered  to Lead  Lender  at the  Closing  together  with a  written
          statement of Viking regarding its planned use of the proceeds from the
          transactions  contemplated  by the  Loan  Documents.  Viking  does not
          presently  engage  in,  and it shall  not  hereafter  engage  in,  any
          activities,  nor shall it use directly or  indirectly  the proceeds of
          the  transactions  contemplated by the Loan Documents for any purpose,
          for  which  an SBIC is  prohibited  from  providing  funds by the SBIC
          Regulations (including 13 C.F.R. Section 107.720).

               11.18.2 The primary business activity of Viking does not involve,
          directly  or  indirectly,  providing  funds to others,  purchasing  or
          discounting  debt  obligations,  factoring  or  long-term  leasing  of
          equipment with no provision for  maintenance or repair,  and Viking is
          not classified under Section 53 (Real Estate) of the NAICS manual. The
          assets of the business of Viking (the  "Business") will not be reduced
          or  consumed,  generally  without  replacement,  as  the  life  of the
          Business  progresses,  and the nature of the Business does not require
          that a stream of cash  payments  be made to the  Business's  financing
          sources, on a basis associated with the continuing sale of assets.

                                       24



          11.19 Solvency. Viking is solvent as of the date of this Agreement and
     will  not  become  insolvent  as  a  result  of  the  consummation  of  the
     transactions  contemplated  by this Agreement or the other Loan  Documents.
     Viking is, and after giving effect to the transactions contemplated by this
     Agreement  shall be, able to pay its debts as they become due, and Viking's
     property now has, and after giving effect to the transactions  contemplated
     hereby shall have, a fair salable value  greater than the amounts  required
     to pay its debts  (including  a  reasonable  estimate  of the amount of all
     contingent  liabilities).  Viking  has  adequate  capital  to  carry on its
     business, and after giving effect to the transactions  contemplated by this
     Agreement,  Viking shall have adequate capital to conduct its business.  No
     transfer of property is being made and no obligation  is being  incurred in
     connection  with the  transactions  contemplated by this Agreement with the
     intent to hinder,  delay or defraud either  present or future  creditors of
     Viking.

          11.20.  Disclosure.  Neither this Agreement, nor any of the other Loan
     Documents, nor any of the schedules,  attachments, or certificates attached
     to this Agreement or any of the other Loan  Documents,  delivered by Viking
     at the Closing,  contains any untrue statements of a material fact or omits
     a  material  fact  necessary  to make the  statements  contained  herein or
     therein  not  misleading.  To  Viking's  knowledge,  there is no fact which
     Viking has not disclosed to Investors,  in writing,  which could reasonably
     be anticipated to have a Material Adverse Effect.

     12.  Representations and Warranties of Investors.  Each Investor represents
and warrants to Viking as follows:

          (a) The Investor is an  "accredited  investor" as such term is defined
     in Rule 501 of Regulation D promulgated by the SEC.

          (b)  Investor  has  had the  opportunity  to ask  questions  of and to
     receive  answers  from Viking and its  executive  officers  concerning  the

     filings of Viking, and desires no further information pertaining to Viking.
     Investor  will  rely  solely  upon (i) such  information  and not any other
     material heretofore  received,  and (ii) investigations made by Investor or
     Investor's representatives in making Investor's investment decision.

          (c)  In  Investor's   opinion,   Investor's   overall   commitment  to
     investments  that are not readily  marketable  is not  disproportionate  to
     Investor's net worth, and in Investor's opinion,  Investor's  investment in
     the  Promissory  Notes  will not  cause  such  overall  commitment  to such
     investments to become excessive.

          (d) Investor has, either alone or together with  Investor's  purchaser
     representative,  if any, such knowledge and  experience in financial,  real
     estate,  and business  matters that Investor is capable of  evaluating  the

          (e) Investor has adequate  means of providing for  Investor's  current
     needs and personal contingencies, and Investor has no need for liquidity in
     Investor's  investment in the Promissory  Notes.  Investor is, able to meet
     Investor's obligations hereunder,  and acknowledges that this investment is
     long-term and speculative in nature.

                                       25



          (f) Investor's personal financial circumstances, investment portfolio,
     and  tax  bracket  are  such  that   Investor  and   Investor's   purchaser
     representative,  if any, believe the purchase  contemplated  herein to be a
     suitable  investment.  Investor is able to bear the  economic  risk of this
     investment.

          (g) The address set forth opposite such Investor's name on Annex A, if
     Investor is an individual,  Investor's  true and correct  residence and, if
     Investor is an entity, Investor's principal place of business.

          (h) Investor acknowledges that if a purchaser  representative has been
     utilized by Investor in evaluating the investment contemplated hereby, that
     Investor's purchaser  representative has advised Investor of the merits and
     risks of an investment in Viking and the suitability of the investment.

          (i) Investor  confirms that Investor is  financially  prepared to hold
     the Promissory  Note for a substantial  period of time and to withstand the
     possibility of a loss of the investment.

          (j) Investor  understands  that none of the Promissory Notes have been
     registered  under the Securities  Act or under any state  securities act in
     reliance on an exemption for non-public offerings.

     subdivision, or fractionalization,  and Investor has no plans to enter into
     any such contract, undertaking,  agreement, or arrangement. Investor agrees
     that the  Promissory  Note to be received  will bear a  restrictive  legend
     limiting transfer.

          (l)  If  Investor  is  a  corporation,   partnership,  or  trust,  the
     undersigned is authorized and otherwise duly qualified to purchase and hold
     the Promissory  Note,  and Investor has its principal  place of business as
     set forth below and was not formed for the  specific  purpose of  acquiring
     the Securities,  unless  otherwise  specifically set forth on the signature
     page hereof.

          (m) Investor  has the full power and  authority to execute and deliver
     this Agreement, and Investor's execution and delivery of this Agreement and
     will not conflict or result in a material  breach of any other agreement or
     obligation to which Investor is a Party.

     13. Affirmative Covenants of Viking. Until the Promissory Notes are paid in
full, Viking shall:

          13.1.  Pay the Loans.  Duly and punctually pay or cause to be paid all

               action, suit or proceeding before any court or other governmental
               authority or other  regulatory body or any arbitrator as to which
               there is a reasonable  possibility of a determination  that would

               (s)  Register  any   securities   under  the  Securities  Act  in
          connection  with an  underwritten  public  offering unless Lead Lender
          reasonably  consents to such registration (it being understood that it
          would not be  unreasonable  for Lead Lender to withhold its consent in
          any such  registration in which Investors would not have  registration
          rights  that are pari passu with each other  holder of  securities  of
          Viking having registration rights); or

               (t) Take any  action,  or fail to take any  action,  which  would
          result in the invalidity,  abandonment,  misuse or unenforceability of
          any  Proprietary  Information  or which  would,  to the  knowledge  of
          Viking, infringe upon or misappropriate any rights of other Persons.

     15. Grant of Preemptive Rights and Co-Sale Rights.

          15.1.  Preemptive Rights. Viking hereby grants to each Investor on the
     terms and conditions set forth herein, a continuing  right,  exercisable by
     the Investors,  in whole or in part, at any time and from time to time (the
     "Preemptive Right") to purchase from Viking, at the times set forth herein,
     shares of Common Stock or Convertible Securities.  Notwithstanding anything
     else contained herein to the contrary,  the Preemptive Right granted herein
     shall only be  available  and may only be  exercised  by an Investor in the
     event Viking issues or offers shares of its Common Stock or any Convertible
     Securities in a non-registered, private offering (a "Private Offering").

               15.1.1.  Number of Shares.  The number of shares of Common  Stock
          (or Convertible Securities representing such Common Stock) that may be
          purchased by an Investor under the Preemptive  Right shall be equal to
          the product of (i) a  fraction,  the  numerator  of which is the total
          number of shares of Common  Stock  owned by  Investor at the time that

                                       31



          were  acquired   pursuant  to  this  Agreement  or  upon  exercise  or
          conversion  of  Securities   acquired   pursuant  to  this   Agreement
          (calculated  on a  fully-diluted  basis  assuming  conversion  of  the
          Promissory  Notes and exercise of the Warrants) and the denominator of
          which is the total  number of such shares of Common  Stock held by all
          Investors  that  were  acquired  pursuant  to this  Agreement  or upon
          exercise  or  conversion  of  Securities  acquired  pursuant  to  this
          Agreement  (calculated on a fully-diluted basis assuming conversion of
          the Promissory Notes and exercise of the Warrants), multiplied by (ii)
          the number of shares of Common Stock  (calculated  on a  fully-diluted
          basis) to be issued or  offered as set forth in the  Preemptive  Right
          Notice (as so calculated, the "Eligible Preemptive Shares").

               15.1.2.  Notice.  Not fewer  than 10  business  days prior to the
          commencement of a Private Offering, Viking will notify in writing each
          of the Investors (a "Preemptive Right Notice").  Each Preemptive Right
          Notice must specify (a) the date on which Viking  proposes to commence
          such Private Offering, (b) the price, number and description of equity
          securities Viking proposes to issue and the other terms and conditions
          of such issuance, and (c) the number of equity securities the Investor
          is entitled to purchase in such Private Offering.

               15.1.3.  Preemptive  Right Exercise and Price. (a) The Preemptive
          Right may be  exercised  by the  Investor  at any time within ten (10)
          business days after receipt of a Preemptive Right Notice  ("Acceptance
          Period") by the delivery to Viking of a written  notice to such effect
          specifying  the number of equity  securities in such Private  Offering
          that that the Investors intends to purchase. Payment therefor shall be
          in  certified  funds as  payment in full for such  equity  securities,
          against delivery of the securities at the principal offices of Viking,
          within five (5) business days after giving Viking such notice,  or, if
          later, the closing date for such Private Offering. Each Investor shall
          also have the option,  exercisable  by so  specifying  in such written
          notice to Viking,  to  purchase  on a pro rata  basis  similar to that
          described  above,  any  remaining   Eligible   Preemptive  Shares  not
          purchased  by  the  other  Investors,   in  which  case  the  Investor
          exercising  such  further  option  shall be deemed to have  elected to
          purchase  such  remaining  Eligible  Preemptive  Shares  on a pro rata
          basis, up to the aggregate number of Eligible  Preemptive Shares which
          such Investor shall have specified  until either (i) no Investor shall
          have elected to purchase any further amount of the Eligible Preemptive
          Shares  which are the subject of the  Preemptive  Right Notice or (ii)
          all the  Eligible  Preemptive  Shares  which  are the  subject  of the
          Preemptive  Right  Notice  shall  have  been  subscribed  for  by  the
          Investors.  Viking shall  promptly  notify each Investor in writing of
          each  notice of  election  received  from  Investors  pursuant to this
          Section.


                    (b) Viking may,  during the sixty (60) day period  following
               the  expiration  of the  Acceptance  Period,  offer the remaining
               unsubscribed   portion  of  the  Common  Stock  (or   Convertible
               Securities  representing  such  Common  Stock)  to any  Person or
               Persons  at a  price  not  less  than,  and  upon  terms  no more
               favorable to the offeree than those  specified in the  Preemptive
               Right Notice.  If Viking does not enter into an agreement for the
               sale of the Common Stock (or Convertible Securities  representing
               such Common  Stock) within such period,  or if such  agreement is
               not consummated within ninety (90) days of the execution thereof,
               the right  provided  hereunder  shall be deemed to be revived and
               such   shares  of  Common   Stock  (or   Convertible   Securities
               representing  such Common  Stock)  shall not be sold unless first
               reoffered to Investor in accordance herewith.

                                       32



                    (c) The  Preemptive  Right may be assigned  by Investor  (or
               assignee  thereof),  in  whole  or in  part,  to an  assignee  of
               Investor.

               15.1.4. Termination of Preemptive Right. The Preemptive Right for
          an Investor  shall  terminate on the date that is six (6) months after
          the date the  Promissory  Note of the Investor has been repaid in full
          or converted in full into Common  Stock;  provided,  however that with
          respect to St. Cloud,  such  Preemptive  Right shall  terminate on the
          later  of (a) the  date  that is six (6)  months  from  the  date  the
          Promissory  Note of St.  Cloud has been repaid in full or converted in
          full  into  Common  Stock or (b) such  date as St.  Cloud  shall  have
          invested in Viking a minimum of $2,000,000 in additional equity.

          15.2.  Co-Sale  Rights.  If Donald  E.  Tucker  ("Major  Shareholder")
     proposes  to sell or  transfer  any  shares  of  Common  Stock in a Private
     Offering  to any  Person  other than a  Permitted  Transferee  (as  defined
     below), in one or more related transactions (other than a transfer pursuant
     to an effective  registration statement and other than transfers under Rule
     144), such Major Shareholder shall provide Investors with written notice of
     the  proposed  transfer  stating the terms and  conditions  of such sale or
     transfer including, without limitation, the number of Common Stock proposed
     to be sold or  transferred,  the  nature of such sale or  transfer  and the
     consideration  to be paid  and the  name and  address  of each  prospective
     purchaser or transferee (the "Major Shareholder  Notice").  Investors shall
     have the right (the "Co-Sale  Right"),  exercisable  upon written notice to
     such Major  Shareholder  within ten (10) business days after receipt of the
     Major Shareholder Notice to participate in such Major Shareholder's sale of
     Common Stock  pursuant to the specified  terms and  conditions set forth in
     the Major  Shareholder  Notice.  To the  extent  Investors  exercises  such
     Co-Sale Right in accordance  with the terms and conditions set forth below,
     the number of shares of Common Stock which such Major  Shareholder may sell
     or transfer  pursuant to the  proposed  sale or transfer  described  in the
     Major  Shareholder  Notice shall be  correspondingly  reduced.  The Co-Sale
     Right of Investors shall be subject to the following terms and conditions:

               15.2.1.  Calculation of Common Stock.  Each Investor may sell all
          or any  part of its  shares  of  Common  Stock  equal  to the  product
          obtained  by  multiplying  (i) the  aggregate  number of Common  Stock
          covered  by the  Major  Shareholder  Notice  by (ii) a  fraction,  the
          numerator of which is the total number of shares of Common Stock owned
          by Investor at the time (calculated on a fully-diluted  basis assuming
          conversion of the Promissory Notes and exercise of the Warrants),  and
          the  denominator of which is the sum of (A) the total number of Common
          Stock owned by all  Investors  exercising  Co-Sale  Rights at the time
          (calculated  on a  fully-diluted  basis  assuming  conversion  of  the
          Promissory  Notes and  exercise  of the  Warrants)  plus (B) the total
          number  of  shares of  Common  Stock at the time  owned by such  Major
          Stockholder  (calculated on a fully-diluted  basis),  including Common
          Stock or Convertible  Securities transferred by such Major Shareholder
          to Permitted Transferees in accordance with this Agreement.

               15.2.2.  Delivery  of  Certificates.   Investor  may  effect  its
          participation in the sale by delivering to such Major  Shareholder for

                                       33



          transfer  to  the  prospective  purchaser  one or  more  certificates,
          properly  endorsed for transfer,  which represent the securities which
          Investor elects to sell.

               15.2.3.  Transfer. The certificate or certificates which Investor
          delivers to such Major Shareholder pursuant to Section 15.2.2 shall be
          delivered by such Major  Shareholder to the  prospective  purchaser in
          consummation  of  the  sale  pursuant  to  the  terms  and  conditions
          specified in the Major Shareholder  Notice, and such Major Shareholder
          shall promptly  thereafter  remit to Investor that portion of the sale
          proceeds to which Investor is entitled by reason of its  participation
          in  such  sale.  To the  extent  that  any  prospective  purchaser  or
          purchasers  prohibits such assignment or otherwise refuses to purchase
          securities  from an Investor  exercising its Co-Sale Right  hereunder,
          such Major Shareholder shall not sell to such prospective purchaser or
          purchasers  any  Common  Stock or  Convertible  Securities  unless and
          until,  simultaneously  with such sale, such Major  Shareholder  shall
          purchase  such   securities   from  such   Investor(s)  for  the  same
          consideration  and on the same terms and  conditions  as the  proposed
          transfer  described in the Major  Shareholder  Notice (which terms and
          conditions shall be no less favorable than those governing the sale to
          the purchaser by such Major Shareholder).

               15.2.4.  Permitted  Transfers.  The provisions of Section 15.2 of
          this Agreement shall not pertain or apply to:

                    (i) Any bona fide gift;

                    (ii) Any transfer pursuant to applicable laws of descent and
               distribution,  to the spouse or any lineal descendant  (including
               by adoption) of such Major Shareholder; or

                    (iii)  Any   transfer   to  a  trust  of  which  such  Major
               Shareholder  is the trustee and which is  established  for estate
               planning purposes.

               Provided  that,  in each case,  that (i) such  Major  Shareholder
          shall inform  Investor of such transfer or gift prior to effecting it,
          and (ii) the transferee or donee (each a "Permitted Transferee") shall
          furnish  Investor  with a written  agreement to be bound by and comply
          with the  provisions  of this  Section 15.2  applicable  to such Major
          Shareholder.

               15.2.5.  Assignment.  The rights  under this  Section 15.2 may be
          assigned by an Investor (or assignee  thereof) to any assignee of such
          Investor.

               15.2.6  Termination.  The  Co-Sale  Right for an  Investor  shall
          terminate  on the  date  that is two (2)  years  after  the  date  the
          Promissory  Note of the  Investor has been repaid in full or converted
          in full into Common Stock.

     16.  Conditions  Precedent.  The  obligations  of the Investors to fund the
Loans hereunder, are subject to the following:

                                       34



          (a)  existing  promissory  notes  evidencing  loans  made by Donald E.
     Tucker to Viking in the total principal  amount of $500,000 shall have been
     converted  into  Common  Stock at the price of $0.40 per share prior to the
     Closing Date; and

          (b) the $100,000  certificate of deposit owned by Donald E. Tucker and
     pledged to Silicon  Valley Bank shall remain pledged to Silicon Valley Bank
     until the loan  relating to such  pledged  certificate  of deposit has been
     paid in full.

     17. SBIC Regulatory Provisions.

          17.1 Use of Proceeds.

               17.1.1 At such times as Lead Lender reasonably  requests,  Viking
          shall deliver to Lead Lender a written statement certified by Viking's
          Chief Financial Officer describing in reasonable detail the use of the
          proceeds from the  transactions  contemplated by the Loan Documents by
          Viking.  In addition to any other  rights  granted  hereunder,  Viking
          shall  grant  Lead  Lender and the SBA  access to  Viking's  books and
          records  for the purpose of  verifying  the use of such  proceeds  and
          verifying the certifications made by Viking in SBA forms Nos. 480, 652
          and 1031,  delivered pursuant to Section 3.1.10 and for the purpose of
          determining   whether  the  principal   business  activity  of  Viking
          continues to  constitute  an eligible  business  activity  (within the
          meaning of the SBIC Regulations).

               17.1.2  Viking shall not use any proceeds  from the  transactions
          contemplated  by  the  Loan  Documents  substantially  for  a  foreign
          operation,  and no more than forty-nine percent (49%) of the employees
          or tangible assets of Viking will be outside the United States (unless
          Viking  can show to the SBA's  satisfaction,  that  proceeds  from the
          transactions  contemplated  by the Loan  Documents  will be used for a
          specific domestic purpose).

               17.1.3  Viking shall not use any proceeds  from the  transactions
          contemplated by the Loan Documents for any purpose  contrary to public
          interest  (including,  but not  limited  to,  activities  which are in
          violation of law) or inconsistent with free enterprise,  in each case,
          within the meaning of 13 C.F.R. Section 107.720.

          17.2 Regulatory Violation

          Upon the  occurrence  of a  Regulatory  Violation or in the event that
     Lead  Lender  determines  in its  good  faith  judgment  that a  Regulatory
     Violation  has  occurred,  in addition to any other  rights and remedies to
     which it may be  entitled  as a holder of the  Securities  under any of the
     Loan  Documents,  Lead Lender  shall have the right to the extent  required
     under  the SBIC  Regulations  to  demand  the  immediate  repayment  of the
     principal balance of the Promissory Notes, plus all accrued interest on the
     Promissory  Notes,  by delivering  written notice of such demand to Viking.
     Viking shall make such payment by a cashier's or certified check or by wire
     transfer of immediately  available  funds to Lead Lender within thirty (30)
     days after Viking's receipt of the demand notice.

          17.3 Regulatory Compliance Cooperation.  In the event that Lead Lender
     believes that it has a Regulatory Problem, Lead Lender shall have the right
     to transfer its Securities  without regard to any  restrictions on transfer

                                       35



     set forth in this  Agreement  or any of the Loan  Documents  other than the
     restrictions  under  applicable  securities  law, and Viking shall take all
     such  actions  as are  reasonably  requested  by Lead  Lender  in  order to
     effectuate  and  facilitate  any transfer by Lead Lender of the  Securities
     then held by Lead Lender to any Person designated by Lead Lender.

          17.4  Economic  Impact  Information.  Promptly  after  the end of each
     calendar year (but in any event prior to February 28 of each year),  Viking
     shall deliver to Lead Lender a written assessment of the economic impact of
     Lead Lender's  investment in Viking,  specifying  the full-time  equivalent
     jobs created or retained in connection with the  investment,  the impact of
     the  investment on the businesses of Viking and on Taxes paid by Viking and
     its employees.

          17.5  Business  Activity.  For a period of one (1) year  following the
     date hereof,  Viking will not change its  business  activity if such change
     would render Viking  ineligible to receive  financial  assistance from Lead
     Lender (within the meanings of 13 C.F.R. Sections 107.720 and 107.760(b)).

          17.6  Number of  Members.  Viking will notify Lead Lender from time to
     time when the number of its shareholders increases to or above or decreases
     below fifty (50).

          17.7 Compliance  With  Non-Discrimination  Requirements.  Viking shall
     comply at all times with the  non-discrimination  requirements of 13 C.F.R.
     Parts 112, 113 and 117.

     18. Lead Lender and Collateral Agent.

          18.1.  Appointment and Authorization.  Each Investor hereby designates
     and  appoints  St.  Cloud as Lead  Lender and  Collateral  Agent under this
     Agreement and the other Loan Documents and each Lender Investor irrevocably
     authorizes the Lead Lender and Collateral  Agent to take such action on its
     behalf under the  provisions of this Agreement and each other Loan Document
     and to  exercise  such  powers and  perform  such  duties as are  expressly
     delegated to it by the terms of this  Agreement or any other Loan Document,
     together   with  such  powers  as  are   reasonably   incidental   thereto.
     Notwithstanding  any provision to the contrary contained  elsewhere in this
     Agreement  or in any other Loan  Document,  the Lead Lender and  Collateral
     Agent shall not have any duties or responsibilities, except those expressly
     set forth  herein or in the Security  Agreement,  nor shall the Lead Lender
     and Collateral  Agent have or be deemed to have any fiduciary  relationship
     with any Investor, and no implied covenants,  functions,  responsibilities,
     duties, obligations or liabilities shall be read into this Agreement or any
     other  Loan  Document  or  otherwise  exist  against  the Lead  Lender  and
     Collateral  Agent.   Without  limiting  the  generality  of  the  foregoing
     sentence,  the use of the term "agent" in this  Agreement with reference to
     the  Collateral  Agent is not  intended to connote any  fiduciary  or other
     implied (or  express)  obligations  arising  under  agency  doctrine of any
     applicable law. Except as expressly  otherwise  provided in this Agreement,
     the  Agent  shall  have and may use its sole  discretion  with  respect  to
     exercising or refraining from exercising any discretionary rights or taking
     or  refraining  from  taking  any  actions  which the  Collateral  Agent is
     expressly  entitled to take or assert  under this  Agreement  and the other
     Loan Documents, including the exercise of remedies, and any action so taken
     or not taken shall be deemed consented to by the Investors.

                                       36



          18.2.  Delegation of Duties.  The Lead Lender and Collateral Agent may
     execute any of its duties under this  Agreement or any other Loan  Document
     by or through agents,  employees or attorneys-in-fact and shall be entitled
     to advice of counsel  concerning all matters pertaining to such duties. The
     Lead  Lender  and  Collateral  Agent  shall  not  be  responsible  for  the
     negligence or misconduct of any agent or  attorney-in-fact  that it selects
     as long as such  selection  was made without  gross  negligence  or willful
     misconduct.

          18.3.  Liability of Lead Lender and Collateral Agent. Neither the Lead
     Lender nor the  Collateral  Agent  (together with its  affiliates,  and the
     officers,  directors,  employees,  counsel,  representatives,   agents  and
     attorneys-in-fact  of the Agent  and such  affiliates,  the  "Agent-Related
     Persons")  shall (i) be liable for any action  taken or omitted to be taken
     by any of them under or in connection with this Agreement or any other Loan
     Document or the transactions  contemplated hereby (except for its own gross
     negligence or willful misconduct),  or (ii) be responsible in any manner to
     any of the Investors for any recital, statement, representation or warranty
     made by Viking  contained in this  Agreement or in any other Loan Document,
     or in any certificate,  report,  statement or other document referred to or
     provided for in, or received by the Collateral Agent under or in connection
     with,  this  Agreement  or  any  other  Loan  Document,  or  the  validity,
     effectiveness, genuineness, enforceability or sufficiency of this Agreement
     or any other Loan Document, or for any failure of Viking or any other party
     to any Loan Document to perform its obligations hereunder or thereunder. No
     Agent-Related  Person  shall be under any  obligation  to any  Investor  to
     ascertain or to inquire as to the  observance or  performance of any of the
     agreements contained in, or conditions of, this Agreement or any other Loan
     Document, or to inspect the properties, books or records of Viking.

          18.4. Reliance by Agent. The Lead Lender and Collateral Agent shall be
     entitled  to rely,  and  shall  be fully  protected  in  relying,  upon any
     writing,  resolution,  notice,  consent,  certificate,  affidavit,  letter,
     telegram,  facsimile,  telex  or  telephone  message,  statement  or  other
     document  or  conversation  believed by it to be genuine and correct and to
     have been signed,  sent or made by the proper  Person or Persons,  and upon
     advice and  statements  of legal  counsel  (including  counsel to  Viking),
     independent  accountants and other experts  selected by the Lead Lender and
     Collateral Agent.

          18.5.  Notice of Default.  The Lead Lender and Collateral  Agent shall
     not be deemed to have  knowledge or notice of the occurrence of any Default
     or Event of Default, unless the Lead Lender and Collateral Agent shall have
     received  written  notice  from an  Investor  or Viking  referring  to this
     Agreement,  describing  such  Default or Event of Default and stating  that
     such notice is a "notice of default." The Lead Lender and Collateral  Agent
     will  notify the  Investors  of its  receipt of any such  notice.  The Lead
     Lender and  Collateral  Agent shall take such  action with  respect to such
     Default or Event of Default as may be requested  by the Required  Investors
     in accordance with the Security Agreement;  provided,  however, that unless
     and until the Lead  Lender  and  Collateral  Agent  has  received  any such
     request,  the Lead  Lender  and  Collateral  Agent  may (but  shall  not be
     obligated  to) take such action,  or refrain from taking such action,  with
     respect to such Default or Event of Default as it shall deem advisable.

          18.6.  Credit Decision.  Each Investor  acknowledges  that none of the
     Agent-Related  Persons has made any  representation  or warranty to it, and
     that no act by the Lead  Lender and  Collateral  Agent  hereinafter  taken,

                                       37



     including  any  review  of the  affairs  of  Viking,  shall  be  deemed  to
     constitute any  representation or warranty by any  Agent-Related  Person to
     any Investor.  Each Investor  represents to the Lead Lender and  Collateral
     Agent  that  it  has,   independently   and  without   reliance   upon  any
     Agent-Related  Person and based on such documents and information as it has
     deemed  appropriate,  made its own appraisal of and investigation  into the
     business,  prospects,  operations,  property, financial and other condition
     and  creditworthiness  of Viking,  and all applicable  bank regulatory laws
     relating to the transactions contemplated hereby, and made its own decision
     to enter  into this  Agreement  and to extend  credit to the  Viking.  Each
     Investor also represents that it will,  independently  and without reliance
     upon any  Agent-Related  Person and based on such documents and information
     as it shall deem  appropriate at the time,  continue to make its own credit
     analysis,  appraisals  and  decisions in taking or not taking  action under
     this   Agreement   and  the  other  Loan   Documents,   and  to  make  such
     investigations  as it deems  necessary to inform itself as to the business,
     prospects,   operations,   property,  financial  and  other  condition  and
     creditworthiness of Viking. Except for notices, reports and other documents
     expressly  required to be furnished to the Investors by the Lead Lender and
     Collateral  Agent herein or under the Security  Agreement,  the Lead Lender
     and Collateral Agent shall not have any duty or  responsibility  to provide
     any Investor with any credit or other information  concerning the business,
     prospects,   operations,   property,   financial  and  other  condition  or
     creditworthiness of Viking which may come into the possession of any of the
     Agent-Related Persons.

          18.7.  Indemnification.  Whether or not the transactions  contemplated
     hereby are  consummated,  the  Investors  shall  indemnify  upon demand the
     Agent-Related  Persons  (to the  extent not  reimbursed  by or on behalf of
     Viking  and  without  limiting  the  obligation  of  Viking  to do so),  in
     accordance with their pro rata interest in the aggregate  principal  amount
     of the Loans, from and against any and all Indemnified  Liabilities as such
     term is defined in Section 19; provided, however, that no Investor shall be
     liable for the payment to the Agent-Related  Persons of any portion of such
     Indemnified   Liabilities   resulting   solely  from  such  Person's  gross
     negligence or willful misconduct. Without limitation of the foregoing, each
     Investor shall  reimburse the Lead Lender and Collateral  Agent upon demand
     for its pro rata interest in the aggregate principal amount of the Loans of
     any costs or  out-of-pocket  expenses  (including  legal fees and expenses)
     incurred by the Lead Lender and  Collateral  Agent in  connection  with the
     preparation, execution, delivery, administration,  modification,  amendment
     or  enforcement  (whether  through   negotiations,   legal  proceedings  or
     otherwise)  of, or legal  advice in respect  of rights or  responsibilities
     under,   this  Agreement,   any  other  Loan  Document,   or  any  document
     contemplated  by or referred to herein,  to the extent that the Lead Lender
     and Collateral Agent is not reimbursed for such expenses by or on behalf of
     Viking.  The  undertaking  in this Section shall survive the payment of all
     Obligations hereunder and the resignation or replacement of the Lead Lender
     and Collateral Agent.

          18.8. Agent in Individual Capacity. The Lead Lender and its affiliates
     may make  loans to,  issue  letters of credit for the  account  of,  accept
     deposits from, acquire equity interests in and generally engage in any kind
     of banking, trust, financial advisory,  underwriting or other business with
     Viking and  affiliates  as though the Lead Lender  were not the  Collateral
     Agent hereunder and without notice to or consent of the Investors. The Lead
     Lender  or  its  affiliates  may  receive   information   regarding  Viking

                                       38



     (including  information that may be subject to confidentiality  obligations
     in favor of Viking) and the Investors acknowledge that the Collateral Agent
     and  the  Lead  Lender  shall  be  under  no  obligation  to  provide  such
     information to them. With respect to its Loans,  the Lead Lender shall have
     the same rights and powers under this  Agreement as any other  Investor and
     may exercise the same as though it were not the Collateral  Agent,  and the
     terms "Investor" and "Investors"  include the Lead Lender in its individual
     capacity.

          18.9.  Successor  Agent. The Collateral Agent may resign as Collateral
     Agent  upon at least  ten (10)  days'  prior  notice to the  Investors  and
     Viking.  Subject to the foregoing,  if the  Collateral  Agent resigns under
     this  Agreement,  the  Required  Investors  shall  appoint  from  among the
     Investors a successor  agent for the  Investors.  If no successor  agent is
     appointed  prior to the effective date of the resignation of the Collateral
     Agent,  the  Collateral  Agent  may  appoint,  after  consulting  with  the
     Investors and Viking, a successor agent from among the Investors.  Upon the
     acceptance of its appointment as successor agent hereunder,  such successor
     agent shall  succeed to all the rights,  powers and duties of the  retiring
     Collateral Agent and the term "Collateral  Agent" shall mean such successor
     agent and the retiring Collateral Agent's appointment, powers and duties as
     Collateral Agent shall be terminated. After any retiring Collateral Agent's
     resignation  hereunder as Collateral  Agent, the provisions of this Article
     18 shall  continue  to  inure to its  benefit  as to any  actions  taken or
     omitted  to be  taken  by it  while  it was  Collateral  Agent  under  this
     Agreement.

          18.10.  Collateral  Matters.  (a)  The  Investors  hereby  irrevocably
     authorize the Collateral  Agent, at its option and in its sole  discretion,
     to release any Liens in the Collateral  granted to the  Investors,  for the
     benefit of the  Investors  pursuant  to this  Agreement  and the other Loan
     Documents  ("Agent's  Liens") (i) upon payment and  satisfaction in full by
     Viking of all Loans and all other Obligations;  (ii) constituting  property
     being sold or disposed of if Viking  certifies to the Collateral Agent that
     the sale or disposition is made in compliance  with the Security  Agreement
     (and the Collateral  Agent may rely  conclusively on any such  certificate,
     without further inquiry); (iii) constituting property in which Viking owned
     no interest at the time the Lien was granted or at any time thereafter;  or
     (iv) constituting property leased to Viking under a lease which has expired
     or been terminated in a transaction permitted under this Agreement.  Except
     as  provided  above,  the  Collateral  Agent  will not  release  any of the
     Collateral  Agent's Liens without the prior  written  authorization  of the
     Investors;  provided  that the  Collateral  Agent may,  in its  discretion,
     release the Collateral  Agent's Liens on Collateral valued in the aggregate
     not in excess of $250,000 during each fiscal year without the prior written
     authorization  of the  Investors and the  Collateral  Agent may release the
     Collateral  Agent's  Liens on  Collateral  valued in the  aggregate  not in
     excess  of  $500,000  during  each  fiscal  year  with  the  prior  written
     authorization of Required  Investors.  Upon request by the Collateral Agent
     or Viking at any time, the Investors will confirm in writing the Collateral
     Agent's  authority to release any Agent's  Liens upon  particular  types or
     items of Collateral pursuant to this Section 18.10.

               (b) Upon  receipt by the  Collateral  Agent of any  authorization
          required  pursuant  to  Section  18.10(a)  from the  Investors  of the
          Collateral  Agent's authority to release Agent's Liens upon particular
          types or items of Collateral, and upon at least five (5) Business Days
          prior written  request by Viking,  the Collateral  Agent shall (and is

                                       39



          hereby  irrevocably  authorized  by the  Investors  to)  execute  such
          documents  as  may  be  necessary  to  evidence  the  release  of  the
          Collateral Agent's Liens upon such Collateral; provided, however, that
          (i) the  Collateral  Agent  shall not be  required to execute any such
          document on terms which,  in the  Collateral  Agent's  opinion,  would
          expose the  Collateral  Agent to liability or create any obligation or
          entail any  consequence  other than the release of such Liens  without
          recourse or warranty,  and (ii) such  release  shall not in any manner
          discharge,  affect or impair the  Obligations or any Liens (other than
          those  expressly  being  released)  upon (or  obligations of Viking in
          respect of) all interests  retained by Viking,  including the proceeds
          of any sale,  all of which shall  continue to  constitute  part of the
          Collateral.

               (c) The Collateral  Agent shall have no obligation  whatsoever to
          any of the Investors to assure that the Collateral  exists or is owned
          by  Viking  or  is  cared  for,  protected  or  insured  or  has  been
          encumbered, or that the Collateral Agent's Liens have been properly or
          sufficiently or lawfully created, perfected,  protected or enforced or
          are entitled to any particular  priority,  or to exercise at all or in
          any  particular  manner  or  under  any duty of  care,  disclosure  or
          fidelity,  or to continue exercising,  any of the rights,  authorities
          and powers  granted or available to the  Collateral  Agent pursuant to
          any of the Loan  Documents,  it being  understood  and agreed  that in
          respect  of the  Collateral,  or any act,  omission  or event  related
          thereto,  the  Collateral  Agent  may act in any  manner  it may  deem
          appropriate,  in its sole discretion given the Collateral  Agent's own
          interest in the Collateral in its capacity as one of the Investors and
          that  the  Collateral  Agent  shall  have no other  duty or  liability
          whatsoever to any Investor as to any of the foregoing.

          18.11. Restrictions on Actions by Investors;  Sharing of Payments. (a)
     Each of the Investors agrees that it shall not, without the express consent
     of all Investors,  and that it shall, to the extent it is lawfully entitled
     to do  so,  upon  the  request  of  all  Investors,  set  off  against  the
     Obligations,  any amounts  owing by such Investor to Viking or any accounts
     of Viking  now or  hereafter  maintained  with such  Investor.  Each of the
     Investors further agrees that it shall not, unless  specifically  requested
     to do so by the Lead Lender and Collateral Agent, take or cause to be taken
     any action to enforce its rights under this  Agreement  or against  Viking,
     including  the  commencement  of any  legal or  equitable  proceedings,  to
     foreclose any Lien on, or otherwise  enforce any security  interest in, any
     of the Collateral.

               (b) If at any time or times any  Investor  shall  receive  (i) by
          payment, foreclosure,  setoff or otherwise, any proceeds of Collateral
          or any  payments  with  respect to the  Obligations  of Viking to such
          Investor  arising  under,  or relating to, this Agreement or the other
          Loan Documents,  except for any such proceeds or payments  received by
          such Investor from the Lead Lender and  Collateral  Agent  pursuant to
          the terms of this Agreement, or (ii) payments from the Lead Lender and
          Collateral  Agent in excess of such Investor's  ratable portion of all
          such distributions by the Agent, such Investor shall promptly (1) turn
          the same over to the Lead Lender and  Collateral  Agent,  in kind, and
          with such endorsements as may be required to negotiate the same to the
          Lead Lender and Collateral Agent, or in same day funds, as applicable,
          for the account of all of the  Investors  and for  application  to the
          Obligations  in  accordance  with the  applicable  provisions  of this
          Agreement, or (2) purchase, without recourse or warranty, an undivided
          interest  and  participation  in the  Obligations  owed  to the  other
          Investors  so that  such  excess  payment  received  shall be  applied

                                       40



          ratably  as among the  Investors  in  accordance  with  their pro rata
          interest in the  aggregate  principal  amount of the Loans;  provided,
          however,  that if all or part of such excess  payment  received by the
          purchasing  party is thereafter  recovered from it, those purchases of
          participations  shall be rescinded in whole or in part, as applicable,
          and the  applicable  portion of the purchase price paid therefor shall
          be returned to such purchasing  party,  but without interest except to
          the extent that such  purchasing  party is required to pay interest in
          connection with the recovery of the excess payment.

          18.12. Agency for Perfection. Each Investor hereby appoints each other
     Investor as agent for the purpose of  perfecting  the  Investors'  security
     interest in assets which,  in  accordance  with Article 9 of the UCC can be
     perfected  only  by  possession.   Should  any  Investor  (other  than  the
     Collateral Agent) obtain  possession of any such Collateral,  such Investor
     shall  notify  the  Collateral  Agent  thereof,   and,  promptly  upon  the
     Collateral  Agent's  request  therefor shall deliver such Collateral to the
     Collateral Agent or in accordance with the Collateral Agent's instructions.

          18.13. Concerning the Collateral and the Related Loan Documents.  Each
     Investor  authorizes  and  directs the  Collateral  Agent to enter into the
     other  Loan  Documents,  for the  ratable  benefit  and  obligation  of the
     Collateral  Agent and the Investors.  Each Investor  agrees that any action
     taken by the Collateral  Agent or Required  Investors,  as  applicable,  in
     accordance  with the terms of this  Agreement or the other Loan  Documents,
     and the  exercise by the  Collateral  Agent or the Required  Investors,  as
     applicable,  of their  respective  powers  set  forth  therein  or  herein,
     together  with such other powers that are  reasonably  incidental  thereto,
     shall be binding upon all of the Investors.  The Investors acknowledge that
     the Loans and all interest, fees and expenses hereunder constitute one debt
     of Viking, secured pari passu by all of the Collateral.

          18.14.  Relation  Among  Investors.  The Investors are not partners or
     co-venturers, and no Investor shall be liable for the acts or omissions of,
     or (except as otherwise set forth herein in case of the  Collateral  Agent)
     authorized to act for, any other Investor.

     19. Indemnity of the Agent and the Investors by Viking.

     Except as set forth in the Registration Rights Agreement,  Viking agrees to
defend, indemnify and hold the Agent-Related Persons, and each Investor and each
of its respective  officers,  directors,  employees,  counsel,  representatives,
agents and  attorneys-in-fact  (each, an "Indemnified Person") harmless from and
against  any and  all  liabilities,  obligations,  losses,  damages,  penalties,
actions, judgments, suits, costs, charges, expenses and disbursements (including
attorney fees) of any kind or nature whatsoever which may at any time (including
at any time following repayment of the Loans and the termination, resignation or
replacement  of the  Collateral  Agent) be imposed  on,  incurred by or asserted
against any such Person in any way relating to or arising out of this  Agreement
or any  document  contemplated  by or  referred to herein,  or the  transactions
contemplated  hereby, or any action taken or omitted by any such Person under or
in  connection  with  any  of  the  foregoing,  including  with  respect  to any
investigation,  litigation or proceeding (including any insolvency proceeding or
appellate  proceeding)  related to or arising out of this  Agreement,  any other
Loan Document,  or the Loans or the use of the proceeds thereof,  whether or not
any Indemnified Person is a party thereto (all the foregoing,  collectively, the
"Indemnified  Liabilities");  provided,  that  Viking  shall have no  obligation
hereunder  to any  Indemnified  Person with respect to  Indemnified  Liabilities

                                       41



resulting  solely from the willful  misconduct of such Indemnified  Person.  The
agreements in this Section shall survive payment of all Obligations.

     20. Representation by Counsel. Each party hereto represents and agrees with
each  other  that  it has  been  represented  by or had  the  opportunity  to be
represented by, independent counsel of its own choosing, and that it has had the
full right and opportunity to consult with its respective  attorney(s),  that to
the  extent,  if any,  that it  desired,  it  availed  itself of this  right and
opportunity,  that it or its  authorized  officers  (as the  case  may be)  have
carefully read and fully  understand this Agreement in its entirety and have had
it fully  explained to them by such  party's  respective  counsel,  that each is
fully aware of the contents  thereof and its meaning,  intent and legal  effect,
and that it or its  authorized  officer  (as the case  may be) is  competent  to
execute  this  Agreement  free from  coercion,  duress or undue  influence.  The
parties to this Agreement  participated  jointly in the negotiation and drafting
of this  Agreement.  If an  ambiguity  or question  of intent or  interpretation
arises,  then this  Agreement  will be  construed  as if drafted  jointly by the
parties  to this  Agreement,  and no  presumption  or burden of proof will arise
favoring or disfavoring  any party to this Agreement by virtue of the authorship
of any of the provisions of this Agreement.

     21. General Provisions.

          21.3. Terms Survive. All agreements, representations,  warranties, and
     covenants  made by Viking shall  survive the execution and delivery of this
     Agreement  and the Loan  Documents  and shall  continue  in full  force and
     effect  so long as any  obligation  to the  Investor  contemplated  by this
     Agreement is outstanding and unpaid and thereafter as herein provided.

          21.4. No Assignment. The parties agree that neither this Agreement nor
     any of the Loan Documents may be assigned by Viking.

          21.5.  Governing Law. This  Agreement and the Loan Documents  shall be
     governed  by and  construed  in  accordance  with the laws of the  State of
     California.

          21.6.  Jurisdiction.  The Parties agree and consent that the courts of
     the State of California shall have jurisdiction with respect to enforcement
     of this Agreement or any Loan Documents executed in connection herewith and
     shall have jurisdiction with respect to any disputes or with respect to any
     legal  proceedings  involving  claims  arising out of this Agreement or the
     Loan Documents.

          21.7.  Amendments.  No  provision  or term of  this  Agreement  may be
     amended,  modified,  revoked,  supplemented,  waived, or otherwise changed,
     except by a written  instrument  duly  executed by Viking and the Investors
     (including  St.  Cloud) and  designated  as an  amendment,  supplement,  or
     waiver.  Viking  agrees to pay any fees incurred by Investors in connection
     with any consent, waiver or amendment of any Loan Document.

          21.8.  Counting of Days. Unless otherwise  indicated,  the term "days"
     when used herein  shall mean  calendar  days.  If any time period ends on a
     Saturday,  Sunday,  or  holiday  officially  recognized  by  the  State  of
     California,  the  period  shall be  deemed  to end on the  next  succeeding
     business day.

                                       43



          21.9.  Headings.  The  article  and  section  headings  herein are for
     convenience only and shall not affect the construction hereof.

          21.10.  Entire Agreement.  This Agreement and the other Loan Documents
     constitute the final  expression of the agreement and  understanding of the
     parties with respect to the general subject matter hereof and supersede any
     previous understanding,  negotiations,  or discussions,  whether written or
     oral.  This  Agreement and the Loan  Documents may not be  contradicted  by
     evidence of any alleged oral agreement.

          21.11.  Conflict.  If the term of any other Loan Document,  except the
     Promissory Note,  shall be in conflict with this Agreement,  this Agreement
     shall govern to the extent of the conflict.  If the terms of this Agreement
     shall be in conflict with the Promissory  Note,  the  Promissory  Note will
     govern to the extent of the conflict.

          21.12.  Use of Terms.  As used  herein,  words in any gender  shall be
     deemed to include the other  genders,  and the singular  shall be deemed to
     include the plural, and vice versa.

          21.13.  Agency.  Nothing  in this  Agreement  shall  be  construed  to
     constitute  the  creation of a  partnership  or joint  venture  between the
     Investors and Viking. No Investor is an agent or representative of Viking.

          21.14.   Authority  to  File  Notices.   Viking  hereby  appoints  and
     designates the Collateral Agent as its attorney-in-fact to file, for record
     any notice that the Collateral Agent deems necessary to protect the Secured
     Parties' interests under the Security Agreement. This power shall be deemed
     coupled  with  an  interest  and  shall  be  irrevocable  while  any sum or
     performance remains due and owing under any of the Loan Documents.

          21.15.  Waiver.  An  Investor  shall not be deemed to have  waived any
     rights  hereunder unless such waiver is given in writing and signed by such
     Investor.  No delay or admission  on the part of an Investor in  exercising
     any right  shall  operate as a waiver of such right or any other  right.  A
     written  waiver by an Investor of a provision of this  Agreement  shall not
     prejudice or  constitute  a waiver of the  Investor's  rights  otherwise to
     demand strict compliance with that provision or any other provision of this
     Agreement.  No prior  written  waiver by the  Investor,  nor any  course of
     dealing between the Investor and Viking,  shall  constitute a waiver of any
     of the  Investor's  rights or  obligations.  Whenever  the  consent  of the
     Investor is required under this Agreement,  the granting of such consent by
     the Investor in any instance  shall not  constitute  continuing  consent in
     subsequent instances where such consent is required, and in all cases, such
     consent may be granted or withheld in the sole discretion of the Investor.

          21.16.  Severability.  If a court of competent  jurisdiction finds any
     provision of this  Agreement or any of the Loan  Documents to be invalid or
     unenforceable  as to any person or  circumstance,  such  finding  shall not
     render that provision  invalid or  unenforceable as to any other persons or
     circumstances. If feasible, any such offending provision shall be deemed to
     be modified to be within the limits of enforceability or validity. However,
     if the offending provision cannot be so modified, it shall be stricken, and
     all other  provisions of this  Agreement in all other respects shall remain
     valid and enforceable.

of the Securities  Purchase  Agreement;  and (ii) each Additional Investor shall
deliver to Viking the  instruments and documents set forth in Section 3.2 of the

     4. Representations and Warranties.

          4.1 Representations and Warranties of Viking. Each Additional Investor
     hereby  acknowledges  receipt of the Securities  Purchase Agreement and the
     exhibits thereto. Viking affirms to each Additional Investor that:





               (i) The  representations  and  warranties  of Viking set forth in
          Section 11 of the Securities  Purchase Agreement were true and correct
          in all respects when made;

               (ii) Such representations and warranties,  which are incorporated
          herein  by this  reference  and made a part  hereof,  remain  true and
          accurate  in all  respects as of the date  hereof,  except for changes
          resulting  from  the  transactions   contemplated  in  the  Securities
          Purchase Agreement.

          4.2  Representations  and  Warranties  of Additional  Investors.  Each
     Additional Investor acknowledges that such Additional Investor has reviewed
     the  representations  and  warranties  set  forth  in  Section  12  of  the
     Securities   Purchase   Agreement   and  agrees   with   Viking  that  such
     representations  and  warranties,  which  are  incorporated  herein by this
     reference  and made a part  hereof,  are true  and  correct  as of the date
     hereof as they relate to such Additional Investor.

     5. Miscellaneous.

     counterparts,  each  of  which  may be  executed  by less  than  all of the
     Additional  Investors,  each of which  shall  be  enforceable  against  the
     parties  actually  executing such  counterparts,  and all of which together
     shall constitute one instrument.
