                                       RECITALS

                Whereas, USE and its affiliated corporation, Crested Corp.
           ("Crested"), own  shares  of  Common Stock of YSFC and have the
           right to convert indebtedness to  additional  shares  of Common
           Stock of YSFC; and

                Whereas,  USE  has  taken  the initiative in founding  and
           organizing YSFC and may be deemed  to be a founder and promoter
           of YSFC; and

                Whereas,  YSFC has or will enter  into  an  Selling  Agent
           Agreement ("Agent  Agreement")  with  RAF  under  which RAF has
           agreed to or will agree to use its best efforts, as  agent  for
           YSFC,  to  place (sell) shares of Common Stock of YSFC for YSFC
           in a private  offering  (the "Private Offering") for up to US$3
           million in gross proceeds; provided that, YSFC and RAF prior to
           the end of the Private Offering  may mutually agree to increase
           the  size  of the Private Offering up  to  a  maximum  of  US$5
           million in gross  proceeds.   Hereafter,  the  shares of Common
           Stock which will be sold in the Private Offering  are  referred
           to  as the "Private Offering Shares" and the information  about
           YSFC and the Private Offering to be delivered to the purchasers
           ("Investors")  in  the  Private  Offering is referred to as the
           "Private Placement Memorandum"; and

                Whereas, RAF will receive, as  a  part of its compensation
           for sale of the Private Offering Shares,  Warrants  to Purchase
           Common  Shares  of  YSFC  ("Agent's  Warrants",  and the future
           holders  of  such  Agent's  Warrants  are  referred  to as  the
           "Warrantholders"); and

                Whereas, the offer and sale of the Private Offering Shares
           will  not  be  registered  with  the  Securities  and  Exchange
           Commission ("SEC") pursuant to Section 5 of the Securities  Act
           of  1933  ("1933  Act")  or  any  state  securities  laws  and,
           therefore,   the   Private   Offering  Shares  will  constitute
           "restricted securities" under SEC Rule 144 and state securities
           laws; and


                Whereas, USE, YSFC and RAF  have  negotiated the terms and
           conditions under which the Investors and  their  assignees will
           have the opportunity to exchange all or a part of their Private
           Offering  Shares for USE Shares if YSFC is not listed  on,  and
           the Common Stock of YSFC is not available for quotation on, the

           conditions under which the Warrantholders  and  the  holders of
           Common Stock of YSFC acquired upon the exercise of the  Agent's
           Warrants  ("Exercise  Shares")  will  have  the  opportunity to
           exchange  all  or a part of their Agent's Warrants or  Exercise
           Shares for USE Warrants  or  for  USE  Shares, respectively, if
           YSFC  is not listed on, and the Common Stock  of  YSFC  is  not
           available for quotation on, NNM during the Listing Period; and

                Whereas, the Common Stock of USE is listed on NNM.

                of the USE Shares on a national securities exchange if the
                USE Shares are listed on a national securities exchange or
                admitted  to  unlisted   trading  privileges  on  such  an

                Shares are listed for trading on another trading system of
                the National Association of Securities  Dealers,  Inc.  If
                the  USE  Shares  are  not  so  listed on such exchange or
                system or admitted to unlisted trading privileges, the USE
                Share Value shall be the average of the closing bid prices
                reported by the National Quotation  Bureau,  Inc.  for the
                five

           not so listed or admitted to unlisted trading privileges and if
           bid  prices  are not so reported, the current value shall be an
           amount, not less than book value, determined in such reasonable
           manner as may  be  prescribed  by the board of directors of the
           Company.

                of Common Stock of USE, with the same terms, including but
                not  limited  to  registration   rights,  as  the  Agent's
                Warrants surrendered in exchange therefor, except that the
                USE  Warrants  shall  be  (i)  exercisable  only  for  the
                unexpired   term   of  the  Agent's  Warrants   and   (ii)
                exercisable to purchase that number of USE Shares equal to
                (a) the product of (x)  the  number  of  shares  of Common
                Stock  underlying  the Agent's Warrants multiplied by  (z)
                the price per share of Common Stock of YSFC in the Private
                Offering divided by  (b)  the  USE  Share Value and except
                that  the  exercise price per share of  the  USE  Warrants
                shall be equal to the USE Share Value.

                 2.  YSFC Notice  to  USE  and  RAF  of  No  NNM  Listing;
           Exchange   Offer  Documents.   At  least  30  days  before  the
           expiration of  the  Listing  Period,  YSFC  shall  give written
           notice to RAF and USE as to whether or not YSFC will  be listed
           on,  and  the Common Stock of YSFC available for quotation  on,

           the first business day after the end of the Listing Period, USE
           shall  mail  the Exchange  Offer  Documents  to  Investors,  to
           Investors'  assignees,  to  the  Warrantholders  and  to  those
           persons who have Exercise Shares.

                 3.  Exchange Offer Terms.

                      a.  To  Investors.  During the Exchange Period, each
                Investor and each Investor's assignee shall have the right
                to exchange all  of part of the Investor's Exchange Shares
                for the number of  fully paid and nonassessable USE Shares
                which equals the Investor's  Exchange Value divided by the
                USE Share Value.

                      b. To Warrantholders and Holders of Exercise Shares.
                During the Exchange Period, each  Warrantholder  and  each
                holder of Exercise Shares shall have the right to exchange
                (i)  all  or  part  of  the  Agent's Warrants owned by the
                Warrantholder for USE Warrants, and/or (ii) all or part of
                the Exercise Shares for USE Shares  on  the  same basis as
                the   Investor's  Exchange  Shares  are  exchangeable   as
                provided in paragraph 3.a above.

                      c.  Receipt  During  Exchange  Period; No Fractions;
                Irrevocable Election.  No notice of election  to  exchange
                which is given after the expiration of the Exchange Period
                will be accepted by USE.  No fractional USE Shares  or USE
                Warrants shall be issued; any fractional USE Share or  USE
                Warrant  which  would otherwise result shall be rounded up
                to  the  next  whole  USE  Share  or  USE  Warrant.   Each
                Investor, each Investor's assignee, each Warrantholder and
                each holder of Exercise  Shares  shall have the right, one
                time  only,  to  exchange some or all  of  the  Investor's
                Exchange Shares, the  Warrantholder's  Agent's Warrants or
                the  Exercise  Shares for USE Shares or USE  Warrants,  as
                applicable.  On the Exchange Date, the notices of election
                to exchange shall  be irrevocable and shall not be changed
                to increase or decrease  the number of Investor's Exchange
                Shares,  Agent's  Warrants  or   Exercise   Shares  to  be
                exchanged.

                       d.  Certificates  for USE Shares and USE  Warrants.
                From  time  to  time  during  the   Exchange   Period  (i)
                certificates for the USE Shares shall be issued  by USE to
                the  persons  exercising  their right of exchange for  USE
                Shares, and (ii) USE Warrants  shall  be  issued by USE to
                the  persons who have exchanged Agent's Warrants  for  USE
                Warrants.

                 4.  Current    Registration    Statement;   Expenses   of
           Registration   and   Qualification.    USE   shall   keep   the
           registration statement current until the day after the last day
           of  the  Exchange  Period.   USE  shall  pay  for all  expenses
           incurred in connection with such registration statement and, in
           addition,   for  all  expenses  incurred  in  connection   with
           registering or qualifying the offer and sale of the USE Shares,
           USE Warrants  and  underlying  USE Shares  under the securities
           laws of the states wherein the Investors, Investors' assignees,
           Warrantholders and each holder of Exercise Shares reside.


           USE shall not pay any commissions  or other compensation to any
           person in connection with such offers and sales.

                 5.  Adjustments  for Recapitalizations;  No  Termination.
           In the event that between  the  date  of  the Private Placement
           Memorandum  and  the  day  after the last day of  the  Exchange
           Period, YSFC or USE declares  any stock dividend or effectuates
           any stock split or undergoes a  capital reorganization or other
           transaction  which changes the kind  or  number  of  shares  of
           Common Stock of YSFC or USE, then full and equitable adjustment
           in the number of USE Shares and USE Warrants shall be made with
           the objective of maintaining after the transaction the relative
           values of the Investor's Exchange Value and the USE Share Value
           before such stock  dividend  or other capital reorganization or
           other  transaction  as if such transaction  had  not  occurred,
           taking into account changes  in  USE  Share  Value  which  have
           resulted  otherwise  than  from  such  stock  dividend or stock
           split, etc.

                USE  and  YSFC agree that from the date of this  Agreement
           until the day after  the  last day of the Exchange, neither USE
           nor YSFC will take or permit  any  action,  including,  but not
           limited  to,  a merger, reorganization or sale of assets, which
           would terminate  or  diminish  the  rights  of  the  Investors,
           Investors'  assignees,  Warrantholders  or  holders of Exercise
           Shares under this Agreement.

                 6.  Injunctive Relief.  USE irrevocably  grants  RAF  and
           its  assignees,  in addition to other legal remedies available,
           the right to apply  for  an  injunction, without bond exceeding
           $500, to enforce USE's covenants  herein  and USE's sole remedy
           in the event of the entry of such injunctive  relief  shall  be
           the  dissolution  of such injunctive relief, if warranted, upon
           hearing duly held (all  claims  for  damages  by  reason of the
           wrongful  issuance  of  such injunction being expressly  waived
           hereby).

                 7.  Complete Agreement;  Governing  Law  and  Expenses of
           Resolution;  Notice.   This  Agreement  represents the complete
           agreement among the parties with respect  to the subject matter
           hereof, except for the Agent Agreement and the Agent's Warrants

           party  which prevails shall be entitled  to  recover  from  the
           other parties  the  costs  and  expenses  (including reasonable

           Agreement shall  be  given  when  postmarked  after having been
