Item 2.  Acquisition of Assets
------------------------------

     On May 28, 1997, the Registrant entered into an Agreement and Plan of
Reorganization and Transition Agreement whereby it acquired Kimbrough Computer
Sales, Inc. d/b/a 3Si Incorporated ("3Si") in a triangular merger.  A transitory
corporation formed for the purpose and wholly owned by the Registrant was merged
with and into 3Si and 3Si was the surviving corporation which is now a wholly
owned subsidiary of the Registrant.

     The Registrant issued 28,333,333 shares of its common stock to three
individuals who were not affiliated with the Registrant prior to the
transaction.  The three individuals, the former owners of 3Si, were Frank
Backes, Frederick Slack and Felipe Larry Valdez.  Messrs. Backes, Slack and
Valdez were elected to the Board of Directors of the Registrant and now comprise
three of its eight members.

     3Si is engaged in computer and Internet sales and service, primarily as a
systems integrator, focusing on Internet security services.  The Company
distributes and resells computer hardware and software and also provides
maintenance service on computers, as well as consulting and training.

     The consideration issued in connection with the transaction was established
through negotiation between the Registrant and the 3Si shareholders.  Moreover,
the Registrant received a fairness opinion as to the financial terms of the
transaction from an independent private investment consulting firm.

     As previously reported, the Registrant has contracted to sell its oil and
gas assets for approximately $1,800,000 subject to adjustment for revenues and
expenses since the effective date of January 1, 1997.  The Board of Directors
resolved on May 20, 1997 to instruct its officers to initiate steps to enable
the Registrant to conduct a self tender offer for a portion of its outstanding
shares (exclusive of those issued in the acquisition).  It is presently
anticipated that offer will be for approximately 6,000,000 shares of the
Registrant's common stock at approximately $0.30 per share to shareholders of
record on May 20, 1997.  The proposed offer may be withdrawn, modified or
ultimately not made, in the Board of Director's sole discretion.  However, it is
presently anticipated that the Registrant will file requisite information with
the Securities and Exchange Commission under Section 13(e)(4) adopted under the
Securities Exchange Act of 1934 within the next 60 days.

                          Independent Auditors' Report
                          ----------------------------

      We have audited the accompanying balance sheets of 3SI as of December 31,
1996 and 1995, and the statements of operations, changes in retained earnings,
and cash flows for the years ended December 31, 1996, 1995 and 1994.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

      We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentations.  We believe that our audits provide a reasonable basis for our
opinion.

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of 3SI as of December 31, 1996
and 1995, and the results of its operations and its cash flows for the years
ended December 31, 1996, 1995 and 1994, in conformity with generally accepted
accounting principles.

Note A - Summary of Significant Accounting Policies

Organization
The Company was incorporated in Colorado in 1979 and is primarily engaged as a
systems integrator, focusing on internet security services.  The Company
distributes and resells computer hardware and software, and also provides
maintenance service on computers, as well as consulting and training.

The principal markets for its services are large corporations located in metro
Denver and Colorado Springs, Colorado.  The corporate offices are located in
Englewood, Colorado.  The Company also maintains offices in Albuquerque, New
Mexico; Raleigh, North Carolina; and Colorado Springs, Colorado.  The Company
obtains substantial hardware from two vendors, but this hardware can be readily
obtained from other sources.

In April 1996, 3SI entered into an sub-contract agreement to provide information
systems support to the U.S. Postal Service.  Revenues for the nine months that
the Company operated  under the agreement in 1996 were approximately $1.8
million.  The Company estimates continuing revenue from the subcontract
agreement to be approximately $3 million per year for the next four years ending
March 31, 2001, (which includes anticipated renewals).

Use of Estimates
The preparation of the Company's financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in these financial statements
and accompanying notes.  Actual results could differ from those estimates.

Depreciation and Amortization
Depreciation and amortization have been provided in amounts sufficient to relate
the cost of depreciable assets to operations over their estimated useful lives
using straight-line and accelerated methods.  Equipment acquired under capital
leases is amortized on a straight-line basis over the lease period.

Income Taxes
The Company has elected S Corporation status.  All earnings are passed through
to the stockholders and taxed on their individual income tax returns.

Cash and Cash Equivalents
For purposes of the statements of cash flows, the Company considers all highly
liquid debt instruments with an original maturity of three months or less to be
cash equivalents.
Financial Instruments
The carrying amounts reported in the balance sheets for all financial
instruments approximates fair value.

                                                   =========       =========

Due to the nature of the business, significant accounts receivables are owed by
a small number of customers.  Generally, the Company does not require collateral
or other security to support customer receivables.
Note C - Revolving Line of Credit

Bank revolving line of credit with interest at 2.5% over prime up to $1,175,000
(subject to certain collateral limitations) which expired April 7, 1997.
Subsequent to its expiration, the Company converted the revolving line of credit
to a note with the bank requiring monthly payments of $80,000 plus interest at
2.5% over prime through September 2, 1997.  The Company anticipates refinancing
this new note prior to its maturity.  The bank facility is collateralized by
substantially all assets of the Company and personal guarantees of three of its
officers, and contains restrictions relating to incurring additional debt and
maintaining certain financial ratios. The balance of the note at December 31,
1996 and 1995 is $1,175,000 and $1,350,000, respectively.

then appropriate and equitable adjustments shall be made hereunder with respect
to the Merger Consideration so that the aggregate relative rights and
obligations of the parties hereto shall not be adversely affected by any such
action.  TYREX agrees that it will take no such action prior to the Closing
hereunder without first obtaining the prior written consent of 3SI and the 3SI
Shareholders.

after the Effective Time, any further action is necessary or desirable to carry
out the purposes of this Agreement or to vest the Surviving Corporation with
full right, title and possession to all assets, property, rights, privileges,
immunities and franchises of 3SI, then the officers and directors of the

     Chief Executive Officer.  3SI and the 3SI Shareholders will cause 3SI's

     representatives of all material facts regarding the corporate documents,
     financial records, assets, obligations, contracts and business operations
     of 3SI.
(c)  Confidentiality.    In connection with the foregoing matters, each party
     hereto has or will be furnishing to the other from time to time with oral
     and written information as to its proprietary products, marketing strategy
     and business plans, significant portions of which each of TYREX and 3SI
     considers to be proprietary and confidential information (herein called the
     "Confidential Information").  Each party acknowledges that "Confidential
     Information", as used herein, does not include any information which (i)
     was or becomes generally available to the public other than as a result of
     an improper disclosure by the other party hereto; (ii) was or becomes
     information available to the other party on a non-confidential basis from a
     third party source that is not bound by a confidentiality obligation to
     either of the parties hereto; (iii) is required to be disclosed by law as
     the result of the securities of TYREX being registered under S12(g) of the
     Securities Exchange Act.

                                       6
<PAGE>
     Each party agrees that Confidential Information will be used solely for the
     purpose of evaluating the Merger contemplated by this Agreement,
     investigating market information and potential markets, and for the parties
     to pursue due diligence and legal disclosure requirements in connection
     with the Merger, and will not be used in the business or operations of the
     party to which such information has been disclosed or used in any other
     way, directly or indirectly, that may detrimental to the interests of the
     party that owns such Confidential Information.  Confidential Information
     may be disclosed to representatives of the party receiving the same who
     need to know such Confidential Material for the purposes described above,
     it being understood that such representatives shall be informed of the
     confidential nature of the Confidential Information and shall be directed
     to treat the Confidential Information confidentially and as proprietary
     information of the party that owns the same.  Each party shall notify the
     other as to the identity of such representatives.  If either party
     receives a request, including a subpoena or similar legal inquiry, to
     disclose any of the Confidential Material, it shall provide the party that
     owns such Confidential Information with prompt notice so that the owner may
     seek appropriate protective relief.

     If the Closing shall fail to occur for any reason, each party shall
     promptly deliver and return all copies of Confidential Information to the
     party which owns the same, and without retaining any copy, notes or
     extracts thereof.

(d)  TYREX Current Financials and Cold-Comfort Letter.  At or prior to the
     Closing, 3SI shall have received from TYREX's independent public
     accountants a so-called "cold-comfort" letter, in form and substance
     satisfactory to 3SI, to the effect that based upon a review of the TYREX
     Interim Financial Statements and their limited procedures set forth in such
     letter, nothing has come to their attention which causes them to believe
     that the such TYREX Interim Financial Statements do not comply in all
     material respects, or are not presented in conformity, with GAAP.

(e)  3SI Financials, TYREX Form 8-K Report and Cold-Comfort Letter.  As promptly
     as possible after the execution of this Agreement, and in any event prior
     to the expiration of thirty (30) days from the Closing Date, 3SI shall
     provide TYREX with current financial statements of 3SI in form and
     substance adequate for TYREX to comply with the instructions to Item 7 of
     Form 8-K required to be filed by TYREX under the Securities Exchange Act
     (the "3SI Financials") and applicable provisions of SEC Regulation S-X.
     Prior to Closing, 3SI shall provide TYREX with a copy of the 3SI Interim
     Financial Statements.  Within fifteen (15) days from the Closing Date, 3SI
     shall have made available to TYREX all information reasonably requested by
     it to comply with Item 2 of From 8-K.  At or prior to the Closing, TYREX
     shall have received from 3SI's independent public accountants a so-called
     "cold-comfort" letter, in form and substance satisfactory to TYREX, to the
     effect that based upon a review of the 3SI Interim Financial Statements and
     their limited procedures set forth in such letter, nothing has come to
     their attention which causes them to believe that the such 3SI Interim
     Financial Statements do not comply in all material respects, or are not
     presented in conformity, with GAAP.

     4.4. Employment Agreements.  At Closing, the Surviving Corporation shall
enter into written employment agreements with each of the three 3SI Shareholders
on mutually satisfactory terms providing, among other things, for the terms and
provisions set forth in Schedule 4.4 attached to this Agreement.

     periods;

(l)  not impose or permit any Security Interest to be imposed upon any of its
     assets;

     Stock at Closing, and repledging newly issued TYREX Stock at Closing;

                                       8

     4.9. Investment Representation by 3SI Shareholders.  Each of 3SI and the
3SI Shareholders understands that the TYREX Common Stock constituting the Merger
Consideration has not been registered under the Securities Act and each of the
3SI Shareholders represents and warrants that he is acquiring such securities at
the Closing hereunder for his own account for investment and not with a view to
the resale or other distribution thereof.  Each of the 3SI Shareholders
acknowledges that such securities may not be resold or transferred unless they
have been effectively registered under the Securities Act or the issuer has
received an opinion of counsel reasonable satisfactory to it to the effect that
any such proposed resale or transfer is exempt from the registration
requirements of the Securities Act.  Each of the 3SI Shareholders acknowledges
that he is familiar with the provisions applicable to the resale of "restricted

the SEC under the Securities Act.

     not limited to those arising out of or relating to this Agreement or the
     construction, interpretation, performance, breach, termination,
     enforceability or validity thereof, or the commercial, economic or other
     relationship of the parties hereto, whether such claim is based on rights,

(b)  Either party may give the other party written notice (a "Dispute Notice")
     of any Dispute which has not been resolved in the normal course of
     business.  Within three (3) days after delivery of the Dispute Notice, the
     receiving party shall submit to the other a written response (the
     "Response").  The Dispute Notice and the Response shall include (i) a
     statement setting forth the position of the party giving such notice and a

     they reasonably deem necessary, to attempt to resolve the Dispute.  All
     reasonable requests for information made by one party to the other will be
     honored.

(c)  If the Dispute has not been resolved within ten (10) days after delivery of
     the Dispute Notice, or if the parties fail to meet within ten (10) days

     evidence or used for impeachment or for any other purpose in any current of
     future arbitration or litigation.

          10.12.2   Mediation

(a)  If the Dispute has not been resolved by negotiation as hereinabove
     provided, the parties shall make a good faith attempt to settle the Dispute
     by mediation pursuant to the provisions of this Section 10.12.2 before
     resorting to arbitration, litigation or any other dispute resolution
     procedure.

(b)  Unless the parties agree otherwise, the mediation shall be conducted in
     accordance with the Commercial Mediation Rules of the American Arbitration
     Association (the "AAA") then in effect by a mediator who (i) has the
     qualifications and experience set forth in paragraph (c) of this Section
     10.12.2 and (ii) is selected as provided in paragraph (d) of this Section
     10.12.2.

(c)  Unless the parties agree otherwise, the mediator shall be a neutral and
     impartial lawyer with excellent academic and professional credentials (i)
     who is or has been practicing law for at least fifteen (15) years,
     specializing in either general commercial litigation or general corporate
     and commercial matters with some familiarity as to securities regulation,
     and (ii) who has had both training and experience as a mediator and who has
     mediated at least ten cases.

(d)  Either party (the "Initiating Party") may initiate mediation of the Dispute
     by giving the other party (the "Recipient Party") written notice (a
     "Mediation Notice") setting forth a list of the names and resumes of
     qualifications and experience of three impartial persons who the Initiating
     Party believes would be qualified as a mediator pursuant to the provisions
     of paragraph (c) hereof.  Within three (3) days after the delivery of the
     Mediation Notice, the Recipient Party shall give a counter-notice (the
     "Counter-Notice") to the Initiating Party in which the Recipient Party may
     designate a person to serve as the mediator from among the three persons
     listed by the Initiating Party in the Mediation Notice in which event such
     designated person shall be the mediator.  If none of the persons listed in
     the Mediation Notice is designated by the Recipient Party to serve as the
     mediator, the Counter-Notice should set forth a list of the names and
     resumes of three impartial persons who the Recipient Party believes would
     be qualified as a mediator pursuant to the provisions of paragraph (c)
     hereof.  Within three (3) days after the delivery of the Counter-Notice,
     the Initiating Party may designate a person to serve as the mediator from
     among the three person listed by the Recipient Party in the Counter-Notice
     in which event such designated person shall be the mediator.  If the
     parties cannot agree on a mediator from the three impartial nominees
     submitted by each party, each party shall strike two names from the other
     party's list, and the mediator shall be selected by lot between the two
     remaining persons on both lists and the two remaining persons on both lists
     will jointly select as the mediator any person who has the qualifications
     and experience set forth in paragraph (c) hereof.  If they are unable to
     agree, immediate arbitration may be instituted by either party.

(e)  Within ten (10) days after the mediator has been selected as provided
     above, both parties and their respective attorneys shall meet with the
     mediator for one mediation session of at least four hours, it being agreed
     that each party representative attending such mediation session shall be a
     Senior Party Representative with authority to settle the Dispute.  If the
     Dispute cannot be settled at such mediation session or at any mutually
     agreed continuation thereof, either party may give the other and the
     mediator a written notice declaring the mediation process at an end, in
     which event then the Dispute shall be resolved by arbitration as
     hereinafter provided.


                                       29
<PAGE>
(f)  All conferences and discussions which occur in connection with the
     mediation conducted pursuant to this Agreement shall be deemed settlement
     discussions, and nothing said or disclosed, nor any document produced,
     which is not otherwise independently discoverable shall be offered or
     received as evidence or used for impeachment or for any other purpose in
     any current or future arbitration or litigation.

(g)  The costs of the mediation shall be shared equally between the parties.

          10.12.3   Arbitration

(a)  If the Dispute has not been resolved by negotiation as provided in Section
     10.12.1 or mediation as provided in Section 10.12.2, then, except as
     otherwise provided in this Section 10.12.3, the Dispute shall be determined
     by arbitration in Denver, Colorado in accordance with the Commercial
     Arbitration rules of the American Arbitration Association ("AAA")[and its
     Supplementary Procedures of Large, Complex Disputes then in effect by one
     arbitrator who (i) has the qualifications and experience set forth in
     paragraph (b) of this Section 10.12.3 and (ii) is selected as provided in
     paragraph (c) of this Section 10.12.3.  The arbitrator(s) shall base their
     award on the terms of this Agreement, and they shall endeavor to follow the
     law and judicial precedents which a United States District Judge sitting in
     the Federal District Court of Wyoming would apply in the event the Dispute
     were litigated in such court.  The parties expressly agree that this
     Agreement shall confer no power or authority upon the arbitrator(s) to
     render any judgment or award that is erroneous in its application of
     substantive law and expressly agree that no such erroneous judgment or
     award shall be eligible for confirmation.  The arbitrator(s) shall render
     their award in writing and, unless both parties agree otherwise, shall
     include an explanation of the reasons for their award, which explanation
     may be limited to the extent necessary to support the award and need not
     attempt to cover all issues raised by the parties.  The arbitration shall
     be governed by the substantive laws of the State of Wyoming applicable to
     contracts made and to be performed therein, without regard to conflicts of
     law rules, and by the arbitration law of the Federal Arbitration Act (Title
     9, U.S. Code), and judgment upon the award rendered by the arbitrator(s)
     may be entered in any court having jurisdiction thereof.

(b)  Every person named on all lists of potential arbitrators shall be a neutral
     and impartial lawyer with excellent academic and professional credentials
     (i) who is or has been practicing law for at least fifteen (15) years,
     specializing in either general commercial litigation or general corporate
     and commercial matters with some familiarity as to securities regulations;
     and (ii) who has had both training and experience as an arbitrator and is
     generally available to serve as an arbitrator.

(c)  The arbitrator shall be selected as provided in this Section 10.12.3 and
     otherwise in accordance with the AAA's Commercial Arbitration Rules then in
     effect, except that each party shall be entitled to strike on a peremptory
     basis, for any reason or no reason, any or all of the names of potential
     arbitrators on any list submitted to the parties by the AAA and any person
     selected by the AAA to serve as an arbitrator by administrative
     appointment.  In the event the parties cannot agree on a mutually
     acceptable arbitrator form the one or more lists submitted by the AAA
     within ten (10) days after the AAA transmits to the parties its first list
     of potential arbitrators, the President of the Colorado Bar Association
     shall designate three persons who, in his or her opinion, meet the criteria
     set forth in paragraph (b) hereof, which designees may include persons

                                       30
<PAGE>
     named on any list submitted by the AAA.  Each party shall be entitled to
     strike one of such three designees on a peremptory basis within 10 days
     after its receipt of such list of designees, indicating its order of
     preference with respect to the remaining designees.  If two of such
     designees have been stricken by the parties, the unstricken designee shall
     be the arbitrator.  Otherwise, the selection of the arbitrator shall be
     made by the AAA from the remaining designees in accordance with their
     mutual order of preference, or by random selection in the absence of a
     mutual order of preference.

     10.13.    Choice of Venue.  Any mediation or arbitration shall take place
in Denver, Colorado.  Any litigation, including litigation arising out of or
concerning such arbitration, shall be conducted exclusively in the Federal
District Court, Denver, Colorado, if applicable, and if not, in the District
Court, Denver County, Colorado.  All parties hereby consent to the jurisdiction
of such court for all litigation.

SECTION 11.    Piggyback Registration Rights.

     11.1.     Definitions.  For purposes of this Section 11:

          (1)  The "Company" means the Surviving Corporation.

            (2)     The term "register," "registered," and "registration" refer
               to a registration effected by preparing and filing a registration
               statement or similar document in compliance with the Act, and the
               declaration or ordering of effectiveness of such registration
               statement or document;

            (3)     The term "Securities with Piggyback Rights" means securities
               of the Company which are entitled upon request to be included in
               a registration effected by the Company (including a registration
               statement effected by the Company for shareholders).

     11.2.     Company Registration.  If (but without any obligation to do so)
the Company proposes to register (including for this purpose a registration
effected by the Company on Form S-8 except for that required to be filed for One
Capital Corporation) any of its stock or securities under the Act, the Company
shall, at such time, promptly give each of the 3SI Shareholders and each of the
present officers and directors of TYREX ("Holders"), written notice of such
registration.  Upon the written request of each such Holder given within twenty
(20) days after mailing of such notice by the Company in accordance with the
notice requirements hereof, the Company shall, subject to the provisions hereof,
cause to be registered under the Act all of the Piggyback Securities.

     11.3.     Furnish Information.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section that the
selling Holders shall furnish to the Company such information regarding
themselves, the Piggyback Securities held by them, and the intended method of
disposition of such securities shall be required to effect the registration of
their Piggyback Securities.

     11.4.     Expenses of Piggyback Registration.  All expenses incurred in
connection with registrations pursuant hereto, including (without limitation)

the reasonable fees and disbursements of counsel for the selling Holders shall
be borne by the Company.

                                       31
<PAGE>
     11.5 Underwriting Requirements.  In connection with any offering involving
an underwriting of shares, the Company shall not be required to include any of
the Holders' securities in such underwriting unless they accept the terms of the
underwriting as agreed upon between the Company and the underwriters selected by
it, and then only in such quantity as will not, in the opinion of the
underwriters, jeopardize the success of the offering by the Company.

     11.6   Delay of Registration.  No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 12.
      11.7 Indemnification.  In the event any Piggyback Securities are included
in a
registration statement under this Section 12:
          (1)     To the extent permitted by law, the Company and the Holders of
          the Piggyback Securities will each indemnify and hold harmless each
          other and the officers, directors and controlling shareholders of the
          Company and any underwriter (as defined in the Act) , against any
          losses, claims, damages, or liabilities joint of several) to which
          they may become subject under the Act, the 1934 Act or other federal
          or state law, insofar as such losses, claims, damages or liabilities
          (or action's in respect thereof arise out of or are based upon any of
          the following statements, omissions or violations (collectively a
          "Violation"): (a) any untrue statement or alleged untrue statement of
          a material fact contained in such registration statement, including
          any preliminary prospectus or final prospectus contained therein or
          any amendments or supplements thereto, (b) the omission or alleged
          omission to state there a material fact required to be stated therein,
          or necessary to make the statements therein not misleading, or (c) any
          violation or alleged violation by the Company of the Act, the 1934
          Act, any state securities law or any rule or regulation promulgated
          under the Act, the 1934 Act or any state securities law; and the
          indemnifying party will reimburse the party indemnified for any legal
          or other expenses reasonably incurred by it in connection with
          investigating or defending any such loss, claim, damage, liability, or
          action.  The Company shall not be liable under any of the foregoing
          circumstances for any such loss, claim, damage, liability, or action
          to the extent that it arises out of or is based upon a Violation which
          occurs in reliance upon and in conformity with written information
          furnished expressly for use in connection with such registration by
          any such Holder of the Piggyback Securities.

          (2)  Promptly after receipt by an indemnified party, under this
          Section of notice of the commencement of any action (including any
          governmental action), such indemnified party will, if a claim in
          respect thereof is to be made against any indemnifying party under
          this Section, notify the indemnifying party in writing of the
          commencement thereof and the indemnifying party shall have the right
          to participate in, and, to the extent the indemnifying party so
          desires, jointly with any other indemnifying party similarly noticed,
          to assume the defense thereof with counsel mutually satisfactory to
          the parties; provided however, that an indemnified party shall have
          the right to retain its own counsel, with the fees and expenses to be
          paid by the indemnifying party, if representation of such indemnified
          party by the counsel retained by the indemnifying party would be
          inappropriate due to actual or potential differing interests between
          such indemnified party and any other represented by such counsel in

                                            32
          <PAGE>
          such proceeding.  The failure to notify an indemnifying party within a
          reasonable time of the commencement of any such action, if prejudicial
          to its ability to defend such action, shall relieve such indemnifying
          party of any liability to the indemnified party under this Section,
          but the omission so to notify the indemnifying party will not relieve
          it of any liability that it may have to any indemnified party
          otherwise than under this Section.

      11.8  Assignment of Registration Rights.  The rights to cause the Company
to register Piggyback Securities pursuant to this Section may not be assigned by
a Holder of such Piggyback Securities, without the prior written consent of the
Company.

      IN WITNESS WHEREOF, each of the parties hereto has executed or caused this
Agreement to be executed all as of the date first written above.

Exhibit 97.10.2
                              TRANSITION AGREEMENT


     This Transition Agreement ("Agreement") is made and entered into this 28th
day of May, 1997 between and among Tyrex Oil Company ("Tyrex"), Kimbrough
Computer Sales, Inc., d/b/a 3Si, Inc. ("3Si") and Fred Slack, Frank Backes and
Larry Valdez (collectively, the "3Si Shareholders") but bound separately hereto
as individuals and as shareholders of 3Si, and Tom N. Richardson ("Richardson"),
individually.  All of the other parties to this Agreement are hereinafter
referred to as the "Parties."

     WHEREAS, the Parties have entered into an Agreement and Plan of
Reorganization dated May 28, 1997 (the "Reorganization Agreement"), pursuant to
which a wholly owned subsidiary of Tyrex will merge with and into 3Si, and
thereafter 3Si will be a wholly owned subsidiary of Tyrex and the 3Si
Shareholders will become shareholders of Tyrex, and

     WHEREAS, Tyrex has heretofore entered into a Purchase and Sale Agreement
relating to the sale of certain of its oil and gas assets for approximately
$1,800,000 of gross proceeds subject to adjustment, which sale is contemplated
to be closed on or before July 1, 1997 (the "Property Sale"), and

     WHEREAS, the Parties wish to provide for a mechanism whereby Tyrex can be
assured of the ability to make a tender offer to its shareholders for certain of
its shares.
     It is and has been, in consideration for the mutual promises and covenants
contained herein and in the Agreement and Plan of Reorganization, agreed as
follows:

     1 . Transition Period.  There shall be a Transition Period (defined below)
         -----------------
during which control of Tyrex will not be changed for purposes of Section 14(f)
of the Securities Exchange Act of 1934 ("'34 Act").  The Transition Period is
hereby defined by the Parties as that period of time between:  (i) the Closing
Date as defined in the Reorganization Agreement; and (ii) the earliest of (x)
completion of the Self Tender Offer (defined below), (y) upon written agreement
of the persons constituting the Boards of Directors of Tyrex and 3Si, or (z)
December 31, 1997, unless extended in writing by the mutual agreement of all
Parties hereto to a date not later than March 31, 1998.  It is understood that
when the Transition Period is terminated, any funds not used in the Self Tender
Offer will become unrestricted funds of Tyrex.

     2.   Board of Directors.  During the Transition Period, the Board of
          ------------------
Directors of Tyrex shall be comprised of eight members, five of whom shall be
designated by Tom N. Richardson and John D. Traut, or their successors or
nominees and three of whom shall be designated by the 3Si Shareholders.  To
effectuate and perpetuate this portion of this Transition Agreement, the Parties
agree further as follows.

      (i)         from and after the Closing Date (as defined in the
     Reorganization Agreement) and until the occurrence of the earliest of the
     conditions described in  Paragraph 1 above, each of Messrs. Valdez, Backes,
     Slack and Richardson (if he continues to be a shareholder of Tyrex after
     the Closing Date) shall vote all of his shares of Tyrex Common Stock and
     any other voting securities of Tyrex over which such shareholder has voting
     control and shall take all other necessary or desirable actions within his
     control (whether in his capacity as a stockholder, director, member of a

                                          1
     <PAGE>
     board committee or officer of Tyrex or otherwise, and including, without
     limitation, attendance at meetings in person or by proxy for purposes of
     obtaining a quorum and execution of written consents in lieu of meetings),
     and Tyrex shall take all reasonable, necessary or desirable actions within
     its control (including, without limitation, calling special board and
     shareholder meetings), to ensure that the size of the Board remains eight
     to ensure the election of, and affirmative vote for, five nominees
     designated by the current Board of Directors of Tyrex and three nominees
     designated by the current Board of 3Si; to insure that Tyrex's Board of
     Directors will support 3Si management and will not take any action which
     will adversely affect 3Si's ability to implement its business plan after
     the merger, which the Tyrex Board understands may include but not be
     limited to arranging of new or increased credit lines; entering into
     strategic alliances or ventures with NETCOM, INACOM, SECURE COMPUTING or
     others (of which 3SI and the 3SI Shareholders hereby represent there are
     presently no agreements, plans, arrangements or understandings, except as
     set forth in the Reorganization Agreement); selling a portion (less than
     7%) of the 3Si Shareholders' stock (after completion or termination of the
     self tender offer); paying off or refinancing the approximate $200,000 Note
     to the Previous Owners of 3Si to obtain the Previous Owners' release of
     their collateral in Tyrex stock; and performing such further acts as may be
     deemed by 3Si management to be in the best interests of Tyrex and its
     shareholders in pursuing the business plan; provided however 3SI may not
     issue, or agree to issue any of its securities or derivatives thereof, or
     take, or attempt to take, any other action during the Transition Period
     which would cause 3Si to be other than a wholly owned subsidiary of Tyrex.
     During the period covered by this Transition Agreement, 3Si will function
     under the control of its Board of Directors with general oversight by the
     Board of Directors of Tyrex necessary to meet their fiduciary duties;
      (ii)  in the event that any representative designated by Tyrex or 3Si
     ceases to serve as a member of the Board during his term of office, the
     resulting vacancy on the Board shall be filled by a representative
     designated by Tyrex if such person was a Tyrex nominee, or by 3Si if such
     person was a 3Si nominee;

      (iii) Messrs. Valdez', Backes', Slack's and Richardson's obligation to
     vote their shares as described in this Transition Agreement constitutes a
     voting Agreement created under the Wyoming Business Corporation Act;

      (iv)  in order to secure each of Messrs. Valdez', Backes', Slack's and
     Richardson's obligation to vote his shareholder shares and other voting
     securities of Tyrex in accordance with the provisions of this Transition
     Agreement, each of Messrs. Valdez, Backes, Slack and Richardson hereby
     appoints Tom N. Richardson as his true and lawful proxy and attorney-in-
     fact, with full power of substitution, to vote all of his shares and other
     voting securities of Tyrex for the election of directors as expressly
     provided for in this Transition Agreement for the modifications described
     in Paragraph 4(vii) below, if any, and for any affirmation or ratification
     set forth in Paragraph 4(viii) below, Tom N. Richardson may exercise the
     irrevocable proxy granted to him hereunder at any time Messrs.  Valdez,
     Backes or Slack fail to comply with the provisions of this Transition
     Agreement.  The proxies and powers granted by Messrs. Valdez, Backes and
     Slack pursuant to this paragraph 2 are coupled with an interest and are
     given to secure the performance of their respective obligations to Tyrex
     under this Transition Agreement.  Such proxies and powers shall be
     irrevocable for the Transition Period and shall survive the death,
     incompetency, disability or bankruptcy of Messrs.  Valdez, Backes or Slack
     or either of them and the subsequent holders of their shares;

     purchaser or transferee is not bound hereby; and

     as members of the Board of Directors of Tyrex which letters shall be held
     in trust by Tom N. Richardson who shall date such letters and deliver them

     Period as described in Paragraph 1(x), (y) and (z) above.

Item 2.  Acquisition of Assets
------------------------------

     On May 28, 1997, the Registrant entered into an Agreement and Plan of
Reorganization and Transition Agreement whereby it acquired Kimbrough Computer
Sales, Inc. d/b/a 3Si Incorporated ("3Si") in a triangular merger.  A transitory
corporation formed for the purpose and wholly owned by the Registrant was merged
with and into 3Si and 3Si was the surviving corporation which is now a wholly
owned subsidiary of the Registrant.

     The Registrant issued 28,333,333 shares of its common stock to three
individuals who were not affiliated with the Registrant prior to the
transaction.  The three individuals, the former owners of 3Si, were Frank
Backes, Frederick Slack and Felipe Larry Valdez.  Messrs. Backes, Slack and
Valdez were elected to the Board of Directors of the Registrant and now comprise
three of its eight members.

     3Si is engaged in computer and Internet sales and service, primarily as a
systems integrator, focusing on Internet security services.  The Company
distributes and resells computer hardware and software and also provides
maintenance service on computers, as well as consulting and training.

     The consideration issued in connection with the transaction was established
through negotiation between the Registrant and the 3Si shareholders.  Moreover,
the Registrant received a fairness opinion as to the financial terms of the
transaction from an independent private investment consulting firm.

     As previously reported, the Registrant has contracted to sell its oil and
gas assets for approximately $1,800,000 subject to adjustment for revenues and
expenses since the effective date of January 1, 1997.  The Board of Directors
resolved on May 20, 1997 to instruct its officers to initiate steps to enable
the Registrant to conduct a self tender offer for a portion of its outstanding
shares (exclusive of those issued in the acquisition).  It is presently
anticipated that offer will be for approximately 6,000,000 shares of the
Registrant's common stock at approximately $0.30 per share to shareholders of
record on May 20, 1997.  The proposed offer may be withdrawn, modified or
ultimately not made, in the Board of Director's sole discretion.  However, it is
presently anticipated that the Registrant will file requisite information with
the Securities and Exchange Commission under Section 13(e)(4) adopted under the
Securities Exchange Act of 1934 within the next 60 days.

                          Independent Auditors' Report
                          ----------------------------

      We have audited the accompanying balance sheets of 3SI as of December 31,
1996 and 1995, and the statements of operations, changes in retained earnings,
and cash flows for the years ended December 31, 1996, 1995 and 1994.  These
financial statements are the responsibility of the Company's management.  Our
responsibility is to express an opinion on these financial statements based on
our audits.

      We conducted our audits in accordance with generally accepted auditing
standards.  Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement.  An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentations.  We believe that our audits provide a reasonable basis for our
opinion.

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of 3SI as of December 31, 1996
and 1995, and the results of its operations and its cash flows for the years
ended December 31, 1996, 1995 and 1994, in conformity with generally accepted
accounting principles.

Note A - Summary of Significant Accounting Policies

Organization
The Company was incorporated in Colorado in 1979 and is primarily engaged as a
systems integrator, focusing on internet security services.  The Company
distributes and resells computer hardware and software, and also provides
maintenance service on computers, as well as consulting and training.

The principal markets for its services are large corporations located in metro
Denver and Colorado Springs, Colorado.  The corporate offices are located in
Englewood, Colorado.  The Company also maintains offices in Albuquerque, New
Mexico; Raleigh, North Carolina; and Colorado Springs, Colorado.  The Company
obtains substantial hardware from two vendors, but this hardware can be readily
obtained from other sources.

In April 1996, 3SI entered into an sub-contract agreement to provide information
systems support to the U.S. Postal Service.  Revenues for the nine months that
the Company operated  under the agreement in 1996 were approximately $1.8
million.  The Company estimates continuing revenue from the subcontract
agreement to be approximately $3 million per year for the next four years ending
March 31, 2001, (which includes anticipated renewals).

Use of Estimates
The preparation of the Company's financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in these financial statements
and accompanying notes.  Actual results could differ from those estimates.

Depreciation and Amortization
Depreciation and amortization have been provided in amounts sufficient to relate
the cost of depreciable assets to operations over their estimated useful lives
using straight-line and accelerated methods.  Equipment acquired under capital
leases is amortized on a straight-line basis over the lease period.

Income Taxes
The Company has elected S Corporation status.  All earnings are passed through
to the stockholders and taxed on their individual income tax returns.

Cash and Cash Equivalents
For purposes of the statements of cash flows, the Company considers all highly
liquid debt instruments with an original maturity of three months or less to be
cash equivalents.
Financial Instruments
The carrying amounts reported in the balance sheets for all financial
instruments approximates fair value.

                                                   =========       =========

Due to the nature of the business, significant accounts receivables are owed by
a small number of customers.  Generally, the Company does not require collateral
or other security to support customer receivables.
Note C - Revolving Line of Credit

Bank revolving line of credit with interest at 2.5% over prime up to $1,175,000
(subject to certain collateral limitations) which expired April 7, 1997.
Subsequent to its expiration, the Company converted the revolving line of credit
to a note with the bank requiring monthly payments of $80,000 plus interest at
2.5% over prime through September 2, 1997.  The Company anticipates refinancing
this new note prior to its maturity.  The bank facility is collateralized by
substantially all assets of the Company and personal guarantees of three of its
officers, and contains restrictions relating to incurring additional debt and
maintaining certain financial ratios. The balance of the note at December 31,
1996 and 1995 is $1,175,000 and $1,350,000, respectively.

submitted to 3SI shareholders; and (ii) the unanimous written consent of all 3SI
shareholders to approve the Merger.

          Each of the 3SI Shareholders hereby covenants and agrees to vote all

contemplated by this Agreement.  Notwithstanding such approval, 3SI may refuse
to proceed with the Merger if conditions precedent to its obligations hereunder
have not been fully satisfied prior to the Effective Time.

     4.3. Certain Due Diligence and Reporting Matters

                                       5
(a)  Investigation by 3SI.  From and after the execution of this Agreement and
     during the full term hereof, TYREX shall permit 3SI and its duly authorized
     representatives to be provided by TYREX with full access to the properties,
     books, records and business operations of TYREX and the TYREX Subsidiary,
     which shall include without limitation copies of all contracts and
     agreements to which TYREX and the TYREX Subsidiary are a party, information
     as to their financial condition and results of operations, and other
     records and information which 3SI and its representatives reasonably deem
     of significance in an investigation of the business, assets, rights,
     liabilities, obligations and prospects of TYREX.  This right of access
     shall include physical inspection of properties and assets as well as the
     review of all pertinent books, records and corporate documents.  3SI and
     its representatives, however, shall not contact or communicate with any
     vendor to, or customer or creditor of, TYREX without the prior consent of
     TYREX's Chief Executive Officer.  TYREX will cause TYREX's officers and
     employees to cooperate fully in said examination and to cause TYREX's
     independent public accountants and outside legal counsel to cooperate fully
     and to make a full and complete disclosure to 3SI and its representatives
     of all material facts regarding the corporate documents, financial records,
     assets, obligations, contracts and business operations of TYREX.

(b)  Investigation by TYREX.    From and after the execution of this Agreement
     and during the full term hereof, 3SI and the 3SI Shareholders shall cause
     3SI to permit TYREX and its duly authorized representatives to be provided
     by 3SI with full access to the properties, books, records and business
     operations of 3SI, which shall include without limitation copies of all
     contracts and agreements to which 3SI is a party, information as to its
     financial condition and results of operations, and other records and
     information which TYREX and its representatives reasonably deem of
     significance in an investigation of the business, assets, rights,
     liabilities, obligations and prospects of 3SI.  This right of access shall
     include physical inspection of properties and assets as well as the review
     of all pertinent books, records and corporate documents.  TYREX and its
     representatives, however, shall not contact or communicate with any vendor
     to, or customer or creditor of, TYREX without the prior consent of 3SI's
     Chief Executive Officer.  3SI and the 3SI Shareholders will cause 3SI's
     officers and employees to cooperate fully in said examination and to cause
     3SI's independent public accountants and outside legal counsel to cooperate
     fully and to make a full and complete disclosure to TYREX and its
     representatives of all material facts regarding the corporate documents,
     financial records, assets, obligations, contracts and business operations
     of 3SI.
(c)  Confidentiality.    In connection with the foregoing matters, each party
     hereto has or will be furnishing to the other from time to time with oral
     and written information as to its proprietary products, marketing strategy
     and business plans, significant portions of which each of TYREX and 3SI
     considers to be proprietary and confidential information (herein called the
     "Confidential Information").  Each party acknowledges that "Confidential
     Information", as used herein, does not include any information which (i)
     was or becomes generally available to the public other than as a result of
     an improper disclosure by the other party hereto; (ii) was or becomes
     information available to the other party on a non-confidential basis from a
     third party source that is not bound by a confidentiality obligation to
     either of the parties hereto; (iii) is required to be disclosed by law as
     the result of the securities of TYREX being registered under S12(g) of the
     Securities Exchange Act.

                                       6
Each party agrees that Confidential Information will be used solely for the
     purpose of evaluating the Merger contemplated by this Agreement,
     investigating market information and potential markets, and for the parties
     to pursue due diligence and legal disclosure requirements in connection
     with the Merger, and will not be used in the business or operations of the
     party to which such information has been disclosed or used in any other
     way, directly or indirectly, that may detrimental to the interests of the
     party that owns such Confidential Information.  Confidential Information
     may be disclosed to representatives of the party receiving the same who
     need to know such Confidential Material for the purposes described above,
     it being understood that such representatives shall be informed of the
     confidential nature of the Confidential Information and shall be directed
     to treat the Confidential Information confidentially and as proprietary
     information of the party that owns the same.  Each party shall notify the
     other as to the identity of such representatives.  If either party
     receives a request, including a subpoena or similar legal inquiry, to
     disclose any of the Confidential Material, it shall provide the party that
     owns such Confidential Information with prompt notice so that the owner may
     seek appropriate protective relief.

     If the Closing shall fail to occur for any reason, each party shall
     promptly deliver and return all copies of Confidential Information to the
     party which owns the same, and without retaining any copy, notes or
     extracts thereof.

(d)  TYREX Current Financials and Cold-Comfort Letter.  At or prior to the
     Closing, 3SI shall have received from TYREX's independent public
     accountants a so-called "cold-comfort" letter, in form and substance
     satisfactory to 3SI, to the effect that based upon a review of the TYREX
     Interim Financial Statements and their limited procedures set forth in such
     letter, nothing has come to their attention which causes them to believe
     that the such TYREX Interim Financial Statements do not comply in all
     material respects, or are not presented in conformity, with GAAP.

(e)  3SI Financials, TYREX Form 8-K Report and Cold-Comfort Letter.  As promptly
     as possible after the execution of this Agreement, and in any event prior
     to the expiration of thirty (30) days from the Closing Date, 3SI shall
     provide TYREX with current financial statements of 3SI in form and
     substance adequate for TYREX to comply with the instructions to Item 7 of
     Form 8-K required to be filed by TYREX under the Securities Exchange Act
     (the "3SI Financials") and applicable provisions of SEC Regulation S-X.
     Prior to Closing, 3SI shall provide TYREX with a copy of the 3SI Interim
     Financial Statements.  Within fifteen (15) days from the Closing Date, 3SI
     shall have made available to TYREX all information reasonably requested by
     it to comply with Item 2 of From 8-K.  At or prior to the Closing, TYREX
     shall have received from 3SI's independent public accountants a so-called
     "cold-comfort" letter, in form and substance satisfactory to TYREX, to the
     effect that based upon a review of the 3SI Interim Financial Statements and
     their limited procedures set forth in such letter, nothing has come to
     their attention which causes them to believe that the such 3SI Interim
     Financial Statements do not comply in all material respects, or are not
     presented in conformity, with GAAP.

     4.4. Employment Agreements.  At Closing, the Surviving Corporation shall
enter into written employment agreements with each of the three 3SI Shareholders
on mutually satisfactory terms providing, among other things, for the terms and
provisions set forth in Schedule 4.4 attached to this Agreement.

                                       7
4.5. Ordinary Course.    Until the Closing occurs or this Agreement is
otherwise terminated, TYREX and 3SI each shall use their best efforts to
preserve, protect and maintain their respective business operations and to
operate the same in the ordinary course of business.  Without limiting the
generality of the foregoing, except with the consent of the other such party
hereto, each of TYREX, the TYREX Subsidiary and 3SI shall:

     practices;

     relating to or proposed to lead to the acquisition, merger or sale of
     substantially all of its assets or shares of capital stock except as
     contemplated by this Agreement;

(g)  not sell or dispose of any material assets or properties, except in the
     ordinary course of business and as contemplated with the Oil and Gas
     Purchase and Sale Agreement;

(h)  not declare, set aside or pay any dividend or make any other distribution
     with respect to its capital stock, nor issue any stock options, warrants or
     other stock rights which would dilute its stock;

(i)  not authorize for issuance, issue, sell or deliver any additional shares of
     its capital stock of any class (except as contemplated by this Agreement)
     or any securities or obligations convertible into shares of its capital
     stock of any class, or issue or grant any option, warrant or other right to
     purchase any shares of capital stock of any class;

(j)  not incur any material obligations or commitments other than in the
     ordinary course of business;

(k)  not incur or become subject to, nor agree to incur or become subject to,
     any debt, obligation or liability, contingent or otherwise, except current
     liabilities in the ordinary course of business and obligations incurred in
     connection with capital asset acquisitions consistent in amounts in prior
     periods;

(l)  not impose or permit any Security Interest to be imposed upon any of its
     assets;

(m)  not make any capital investment in, make any loan to, or acquire the
     securities or assets of any other person, except that the 3SI Shareholders
     have disclosed to, and received approval of TYREX, to continue the Stock
     Pledge Agreement with the Previous Owners by releasing the existing 3SI
     Stock at Closing, and repledging newly issued TYREX Stock at Closing;

                                       8
(n)  not grant any salary increases (other than as required by existing
     contracts or consistent with past practice), unscheduled promotions or
     enter into any new employment or benefit contracts.

     4.6. Support of the Merger.  Subject to the performance and satisfaction of
conditions precedent to the Closing, TYREX and 3SI agree to propose, advocate,
support and vote for the Merger contemplated by Section 3 of this Agreement, and

Agreement.

     4.8. Notices and Consents.  In the event either TYREX or 3SI is required to
give any notices to third parties and/or to obtain any third-party consents to
complete the Merger, all such notices shall have been required and such consents

     4.9. Investment Representation by 3SI Shareholders.  Each of 3SI and the
3SI Shareholders understands that the TYREX Common Stock constituting the Merger
Consideration has not been registered under the Securities Act and each of the
3SI Shareholders represents and warrants that he is acquiring such securities at
the Closing hereunder for his own account for investment and not with a view to
the resale or other distribution thereof.  Each of the 3SI Shareholders
acknowledges that such securities may not be resold or transferred unless they
have been effectively registered under the Securities Act or the issuer has
received an opinion of counsel reasonable satisfactory to it to the effect that
any such proposed resale or transfer is exempt from the registration
requirements of the Securities Act.  Each of the 3SI Shareholders acknowledges
that he is familiar with the provisions applicable to the resale of "restricted
securities" within the meaning and the limitations of Rule 144 promulgated by
the SEC under the Securities Act.

     4.10.     Other Documents and Conditions to Exchange Closing.   At the
Closing, 3SI and TYREX shall deliver to each other all certificates, instruments
and documents referred to in this Agreement or reasonably requested by their
respective counsel as conditions to Closing.  All conditions precedent to the
Closing set forth in Sections 3 and 4 of this Agreement shall have been fully
performed and satisfied, or waived in writing by the parties hereto, at or prior
to the Closing Date.

     5.7. Financial Statements and Related Matters.

(a)  SEC Reports.   TYREX has made all filings with the SEC that it has been
     required to make under the Securities Act and the Securities Exchange Act
     (all of such filings by TYREX with the SEC are collectively called the

     filed with the SEC has complied with the Securities Act and the Securities
     Exchange Act in all material respects.  None of the Public Reports, as of
     their respective dates, contained any untrue statement of a material fact

                                         11
or omitted to state a material fact necessary in order to make the
     statements made therein, in light of the circumstances under which they
     were made, not misleading.  TYREX has delivered to 3SI a correct and
     complete copy of each of the Public Reports filed by TYREX with the SEC
     since January 1, 1995 (together with all material exhibits thereto and as
     amended to date).

     regulations, including but not limited to SEC reporting requirements,
     disclosure rules, and insider trading rules.

(c)  Financial Statements and Liabilities.  The audited financial statements of
     TYREX for the years ended June 30, 1995 and 1996 contained in the Public

     Financial Statements are and will be: (i)  accurate, correct and complete
     in all material respects; (ii) in accordance with the books of account and
     records of TYREX; (c) fair presentations of the financial condition and
     results of operations of TYREX as of the dates and for the periods
     indicated therein; and (d) prepared in accordance with GAAP.  Except to the
     extent reflected on the balance sheet included in the TYREX Interim
     Financial Statements, or as otherwise contemplated herein, TYREX does not
     have any indebtedness, liabilities or obligations of any nature, whether
     absolute, accrued, contingent or otherwise as of the date of this Agreement
     and the Closing.  The TYREX Subsidiary will not own any assets or have any
     liabilities of any nature, whether absolute, accrued, contingent or
     otherwise as of the Closing.

(e)  Interim Change.  Since the date of TYREX's Interim Financial Statements,
     there has not been (a) any material adverse change in the financial

     relationships with suppliers, customers, distributors, lenders, lessors or
     others; (b) any damage, destruction or loss, whether or not covered by
     insurance, materially adversely affecting TYREX; (c) any event or condition
     or series of events or conditions which could, individually or in the

     TYREX; or (d) any development which could or will have a material adverse
     effect on TYREX.

     5.8. Accounts Receivable.   All outstanding accounts receivable reflected
on the TYREX Interim Financial Statements and incurred in the ordinary course of
business since the date of such Interim Financial Statements, and as of the
Closing Date, will be, due and valid claims against account debtors for goods or
services delivered or rendered, collectible in full within 120 days of delivery
and subject to no defenses, offsets or counterclaims, except as reserved against
in the TYREX Interim Financial Statements in accordance with GAAP.  All
receivables arose in the ordinary course of business, and no receivables are
subject to prior assignment, adverse claims, liens or security interests except
for claims of secured debt reflected on the TYREX Interim Financial Statements.
TYREX has provided sufficient reserves in the TYREX Interim Financial Statements
to cover any liabilities to customers for discounts, returns, promotional

being used, and are adequate to meet all present requirements of the business of
TYREX as currently conducted.

     5.10.     Employees.

(a)  Employment Contracts.  Except as set forth in Schedule 5.10(A), there are
     no agreements, arrangements or understandings, written or oral, with

     agreed continuation thereof, either party may give the other and the
     mediator a written notice declaring the mediation process at an end, in

     paragraph (b) of this Section 10.12.3 and (ii) is selected as provided in
     paragraph (c) of this Section 10.12.3.  The arbitrator(s) shall base their
     award on the terms of this Agreement, and they shall endeavor to follow the
     law and judicial precedents which a United States District Judge sitting in
     the Federal District Court of Wyoming would apply in the event the Dispute
     were litigated in such court.  The parties expressly agree that this
     Agreement shall confer no power or authority upon the arbitrator(s) to
     render any judgment or award that is erroneous in its application of
     substantive law and expressly agree that no such erroneous judgment or
     award shall be eligible for confirmation.  The arbitrator(s) shall render
     their award in writing and, unless both parties agree otherwise, shall
     include an explanation of the reasons for their award, which explanation
     may be limited to the extent necessary to support the award and need not
     attempt to cover all issues raised by the parties.  The arbitration shall
     be governed by the substantive laws of the State of Wyoming applicable to
     contracts made and to be performed therein, without regard to conflicts of
     law rules, and by the arbitration law of the Federal Arbitration Act (Title
     9, U.S. Code), and judgment upon the award rendered by the arbitrator(s)
     may be entered in any court having jurisdiction thereof.

(b)  Every person named on all lists of potential arbitrators shall be a neutral
     and impartial lawyer with excellent academic and professional credentials
     (i) who is or has been practicing law for at least fifteen (15) years,
     specializing in either general commercial litigation or general corporate
     and commercial matters with some familiarity as to securities regulations;
     and (ii) who has had both training and experience as an arbitrator and is
     generally available to serve as an arbitrator.

(c)  The arbitrator shall be selected as provided in this Section 10.12.3 and
     otherwise in accordance with the AAA's Commercial Arbitration Rules then in
     effect, except that each party shall be entitled to strike on a peremptory
     basis, for any reason or no reason, any or all of the names of potential
     arbitrators on any list submitted to the parties by the AAA and any person
     selected by the AAA to serve as an arbitrator by administrative
     appointment.  In the event the parties cannot agree on a mutually
     acceptable arbitrator form the one or more lists submitted by the AAA
     within ten (10) days after the AAA transmits to the parties its first list
     of potential arbitrators, the President of the Colorado Bar Association
     shall designate three persons who, in his or her opinion, meet the criteria
     set forth in paragraph (b) hereof, which designees may include persons

                                       30
named on any list submitted by the AAA.  Each party shall be entitled to
     strike one of such three designees on a peremptory basis within 10 days
     after its receipt of such list of designees, indicating its order of
     preference with respect to the remaining designees.  If two of such
     designees have been stricken by the parties, the unstricken designee shall
     be the arbitrator.  Otherwise, the selection of the arbitrator shall be
     made by the AAA from the remaining designees in accordance with their
     mutual order of preference, or by random selection in the absence of a
     mutual order of preference.

     10.13.    Choice of Venue.  Any mediation or arbitration shall take place
in Denver, Colorado.  Any litigation, including litigation arising out of or
concerning such arbitration, shall be conducted exclusively in the Federal
District Court, Denver, Colorado, if applicable, and if not, in the District
Court, Denver County, Colorado.  All parties hereby consent to the jurisdiction
of such court for all litigation.

SECTION 11.    Piggyback Registration Rights.

     11.1.     Definitions.  For purposes of this Section 11:

          (1)  The "Company" means the Surviving Corporation.

            (2)     The term "register," "registered," and "registration" refer
               to a registration effected by preparing and filing a registration
               statement or similar document in compliance with the Act, and the
               declaration or ordering of effectiveness of such registration
               statement or document;

            (3)     The term "Securities with Piggyback Rights" means securities
               of the Company which are entitled upon request to be included in
               a registration effected by the Company (including a registration
               statement effected by the Company for shareholders).

     11.2.     Company Registration.  If (but without any obligation to do so)
the Company proposes to register (including for this purpose a registration
effected by the Company on Form S-8 except for that required to be filed for One
Capital Corporation) any of its stock or securities under the Act, the Company
shall, at such time, promptly give each of the 3SI Shareholders and each of the
present officers and directors of TYREX ("Holders"), written notice of such
registration.  Upon the written request of each such Holder given within twenty
(20) days after mailing of such notice by the Company in accordance with the
notice requirements hereof, the Company shall, subject to the provisions hereof,
cause to be registered under the Act all of the Piggyback Securities.

     11.3.     Furnish Information.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section that the
selling Holders shall furnish to the Company such information regarding
themselves, the Piggyback Securities held by them, and the intended method of
disposition of such securities shall be required to effect the registration of
their Piggyback Securities.

     11.4.     Expenses of Piggyback Registration.  All expenses incurred in
connection with registrations pursuant hereto, including (without limitation)
all registration, filing and qualification fees, printers' and accounting fees,
audit fees, if required, fees and disbursements of counsel for the Company, and
the reasonable fees and disbursements of counsel for the selling Holders shall
be borne by the Company.

                                       31
11.5 Underwriting Requirements.  In connection with any offering involving
an underwriting of shares, the Company shall not be required to include any of
the Holders' securities in such underwriting unless they accept the terms of the
underwriting as agreed upon between the Company and the underwriters selected by
it, and then only in such quantity as will not, in the opinion of the
underwriters, jeopardize the success of the offering by the Company.

     11.6   Delay of Registration.  No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 12.
      11.7 Indemnification.  In the event any Piggyback Securities are included
in a
registration statement under this Section 12:
          (1)     To the extent permitted by law, the Company and the Holders of
          the Piggyback Securities will each indemnify and hold harmless each
          other and the officers, directors and controlling shareholders of the
          Company and any underwriter (as defined in the Act) , against any
          losses, claims, damages, or liabilities joint of several) to which
          they may become subject under the Act, the 1934 Act or other federal
          or state law, insofar as such losses, claims, damages or liabilities
          (or action's in respect thereof arise out of or are based upon any of
          the following statements, omissions or violations (collectively a
          "Violation"): (a) any untrue statement or alleged untrue statement of
          a material fact contained in such registration statement, including
          any preliminary prospectus or final prospectus contained therein or
          any amendments or supplements thereto, (b) the omission or alleged
          omission to state there a material fact required to be stated therein,
          or necessary to make the statements therein not misleading, or (c) any
          violation or alleged violation by the Company of the Act, the 1934
          Act, any state securities law or any rule or regulation promulgated
          under the Act, the 1934 Act or any state securities law; and the
          indemnifying party will reimburse the party indemnified for any legal
          or other expenses reasonably incurred by it in connection with
          investigating or defending any such loss, claim, damage, liability, or
          action.  The Company shall not be liable under any of the foregoing
          circumstances for any such loss, claim, damage, liability, or action
          to the extent that it arises out of or is based upon a Violation which
          occurs in reliance upon and in conformity with written information
          furnished expressly for use in connection with such registration by
          any such Holder of the Piggyback Securities.

          (2)  Promptly after receipt by an indemnified party, under this
          Section of notice of the commencement of any action (including any
          governmental action), such indemnified party will, if a claim in
          respect thereof is to be made against any indemnifying party under
          this Section, notify the indemnifying party in writing of the
          commencement thereof and the indemnifying party shall have the right
          to participate in, and, to the extent the indemnifying party so
          desires, jointly with any other indemnifying party similarly noticed,
          to assume the defense thereof with counsel mutually satisfactory to
          the parties; provided however, that an indemnified party shall have
          the right to retain its own counsel, with the fees and expenses to be
          paid by the indemnifying party, if representation of such indemnified
          party by the counsel retained by the indemnifying party would be
          inappropriate due to actual or potential differing interests between
          such indemnified party and any other represented by such counsel in

                                            32
such proceeding.  The failure to notify an indemnifying party within a
          reasonable time of the commencement of any such action, if prejudicial
          to its ability to defend such action, shall relieve such indemnifying
          party of any liability to the indemnified party under this Section,
          but the omission so to notify the indemnifying party will not relieve
          it of any liability that it may have to any indemnified party
          otherwise than under this Section.

      11.8  Assignment of Registration Rights.  The rights to cause the Company
to register Piggyback Securities pursuant to this Section may not be assigned by
a Holder of such Piggyback Securities, without the prior written consent of the
Company.

      IN WITNESS WHEREOF, each of the parties hereto has executed or caused this
Agreement to be executed all as of the date first written above.

Exhibit 97.10.2
                              TRANSITION AGREEMENT

     This Transition Agreement ("Agreement") is made and entered into this 28th
day of May, 1997 between and among Tyrex Oil Company ("Tyrex"), Kimbrough
Computer Sales, Inc., d/b/a 3Si, Inc. ("3Si") and Fred Slack, Frank Backes and
Larry Valdez (collectively, the "3Si Shareholders") but bound separately hereto
as individuals and as shareholders of 3Si, and Tom N. Richardson ("Richardson"),
individually.  All of the other parties to this Agreement are hereinafter
referred to as the "Parties."

     WHEREAS, the Parties have entered into an Agreement and Plan of
Reorganization dated May 28, 1997 (the "Reorganization Agreement"), pursuant to
which a wholly owned subsidiary of Tyrex will merge with and into 3Si, and
thereafter 3Si will be a wholly owned subsidiary of Tyrex and the 3Si
Shareholders will become shareholders of Tyrex, and

     WHEREAS, Tyrex has heretofore entered into a Purchase and Sale Agreement
relating to the sale of certain of its oil and gas assets for approximately
$1,800,000 of gross proceeds subject to adjustment, which sale is contemplated
to be closed on or before July 1, 1997 (the "Property Sale"), and

     WHEREAS, the Parties wish to provide for a mechanism whereby Tyrex can be
assured of the ability to make a tender offer to its shareholders for certain of
its shares.
     It is and has been, in consideration for the mutual promises and covenants
contained herein and in the Agreement and Plan of Reorganization, agreed as
follows:

     1 . Transition Period.  There shall be a Transition Period (defined below)
         -----------------
during which control of Tyrex will not be changed for purposes of Section 14(f)
of the Securities Exchange Act of 1934 ("'34 Act").  The Transition Period is
hereby defined by the Parties as that period of time between:  (i) the Closing
Date as defined in the Reorganization Agreement; and (ii) the earliest of (x)
completion of the Self Tender Offer (defined below), (y) upon written agreement
of the persons constituting the Boards of Directors of Tyrex and 3Si, or (z)
December 31, 1997, unless extended in writing by the mutual agreement of all
Parties hereto to a date not later than March 31, 1998.  It is understood that
when the Transition Period is terminated, any funds not used in the Self Tender
Offer will become unrestricted funds of Tyrex.

     2.   Board of Directors.  During the Transition Period, the Board of
          ------------------
Directors of Tyrex shall be comprised of eight members, five of whom shall be
designated by Tom N. Richardson and John D. Traut, or their successors or
nominees and three of whom shall be designated by the 3Si Shareholders.  To
effectuate and perpetuate this portion of this Transition Agreement, the Parties
agree further as follows.

      (i)         from and after the Closing Date (as defined in the
     Reorganization Agreement) and until the occurrence of the earliest of the
     conditions described in  Paragraph 1 above, each of Messrs. Valdez, Backes,
     Slack and Richardson (if he continues to be a shareholder of Tyrex after
     the Closing Date) shall vote all of his shares of Tyrex Common Stock and
     any other voting securities of Tyrex over which such shareholder has voting
     control and shall take all other necessary or desirable actions within his
     control (whether in his capacity as a stockholder, director, member of a

                                          1
board committee or officer of Tyrex or otherwise, and including, without
     limitation, attendance at meetings in person or by proxy for purposes of
     obtaining a quorum and execution of written consents in lieu of meetings),
     and Tyrex shall take all reasonable, necessary or desirable actions within
     its control (including, without limitation, calling special board and
     shareholder meetings), to ensure that the size of the Board remains eight
     to ensure the election of, and affirmative vote for, five nominees
     designated by the current Board of Directors of Tyrex and three nominees
     designated by the current Board of 3Si; to insure that Tyrex's Board of
     Directors will support 3Si management and will not take any action which
     will adversely affect 3Si's ability to implement its business plan after
     the merger, which the Tyrex Board understands may include but not be
     limited to arranging of new or increased credit lines; entering into
     strategic alliances or ventures with NETCOM, INACOM, SECURE COMPUTING or
     others (of which 3SI and the 3SI Shareholders hereby represent there are
     presently no agreements, plans, arrangements or understandings, except as
     set forth in the Reorganization Agreement); selling a portion (less than
     7%) of the 3Si Shareholders' stock (after completion or termination of the
     self tender offer); paying off or refinancing the approximate $200,000 Note
     to the Previous Owners of 3Si to obtain the Previous Owners' release of
     their collateral in Tyrex stock; and performing such further acts as may be
     deemed by 3Si management to be in the best interests of Tyrex and its
     shareholders in pursuing the business plan; provided however 3SI may not
     issue, or agree to issue any of its securities or derivatives thereof, or
     take, or attempt to take, any other action during the Transition Period
     which would cause 3Si to be other than a wholly owned subsidiary of Tyrex.
     During the period covered by this Transition Agreement, 3Si will function
     under the control of its Board of Directors with general oversight by the
     Board of Directors of Tyrex necessary to meet their fiduciary duties;
      (ii)  in the event that any representative designated by Tyrex or 3Si
     ceases to serve as a member of the Board during his term of office, the
     resulting vacancy on the Board shall be filled by a representative
     designated by Tyrex if such person was a Tyrex nominee, or by 3Si if such
     person was a 3Si nominee;

      (iii) Messrs. Valdez', Backes', Slack's and Richardson's obligation to
     vote their shares as described in this Transition Agreement constitutes a
     voting Agreement created under the Wyoming Business Corporation Act;

      (iv)  in order to secure each of Messrs. Valdez', Backes', Slack's and
     Richardson's obligation to vote his shareholder shares and other voting
     securities of Tyrex in accordance with the provisions of this Transition
     Agreement, each of Messrs. Valdez, Backes, Slack and Richardson hereby
     appoints Tom N. Richardson as his true and lawful proxy and attorney-in-
     fact, with full power of substitution, to vote all of his shares and other
     voting securities of Tyrex for the election of directors as expressly
     provided for in this Transition Agreement for the modifications described
     in Paragraph 4(vii) below, if any, and for any affirmation or ratification
     set forth in Paragraph 4(viii) below, Tom N. Richardson may exercise the
     irrevocable proxy granted to him hereunder at any time Messrs.  Valdez,
     Backes or Slack fail to comply with the provisions of this Transition
     Agreement.  The proxies and powers granted by Messrs. Valdez, Backes and
     Slack pursuant to this paragraph 2 are coupled with an interest and are
     given to secure the performance of their respective obligations to Tyrex
     under this Transition Agreement.  Such proxies and powers shall be
     irrevocable for the Transition Period and shall survive the death,
     incompetency, disability or bankruptcy of Messrs.  Valdez, Backes or Slack
     or either of them and the subsequent holders of their shares;

                                       2
(v)   Messrs.  Valdez, Backes, Slack and Richardson shall not grant any
     proxy or become party to any voting trust or other Agreement which is
     inconsistent with, conflicts with, or violates any provision of this
     Agreement nor shall Messrs.  Valdez, Backes and Slack assign, sell or
     transfer any Tyrex shares under circumstances where such assignee,
     purchaser or transferee is not bound hereby; and

      (vi)  Messrs.  Traut, Gruman and Massey will sign letters of resignation
     as members of the Board of Directors of Tyrex which letters shall be held
     in trust by Tom N. Richardson who shall date such letters and deliver them
     to Tyrex upon the earliest event to cause termination of the Transition
     Period as described in Paragraph 1(x), (y) and (z) above.

      3.    '34 Act Information and Filings.  The Parties acknowledge that Tyrex
             ------------------------------
is obligated to file certain information regarding the Reorganization Agreement,
the Self Tender Offer and other matters under various provisions of the '34 Act,
as are the 3Si Shareholders, individually and/or as a group. 3Si and the 3Si
Shareholders and Richardson agree specifically that:

      (i)   information in form and substance necessary to enable Tyrex to
     comply with Form 8-K, including among other things, Items 2 and 7, therein
     will be made available to Tyrex within 15 days and 30 days, respectively,
     from the date hereof; and

      (ii)  information in form and substance necessary to enable Tyrex to file
     the Self Tender Offer will be made available to Tyrex within 30 days from
     the date hereof.

      The Parties further acknowledge that the proposed Self Tender Offer is an
integral part of the overall reorganization of Tyrex and therefore that each
will do whatever is reasonably requested to effectuate the Self Tender Offer as
expeditiously as possible, and to that end 3Si will cause Larry Valdez and Paul
Kaufhold to devote whatever time is reasonably requested to work with Tyrex and
its agents in completing the Self Tender Offer.

      More specifically, Mr. Kaufhold will use his best efforts to deliver
within thirty (30) days after the Closing Date a draft in proper and customary
form suitable in the opinion of Jones & Keller, P.C., or any independent
successor counsel to Tyrex, for inclusion in the Self Tender Offer document.
Such document and the related financial statements will fully comply in form and
content with applicable provisions of:

            (i)   Rule 13e-4 and Schedule 13E-4;

            (ii)  Regulation S-K;

            (iii) Regulation S-X.

Within ten (10) days after receipt of any comment letter(s) from the Securities
and Exchange Commission with respect to such filing, Mr. Kaufhold will use his
best efforts to provide full and adequate documentation to enable Tyrex to amend
such filing(s) in accordance with such comments.

                                       3
4.    Self Tender Offer.  The Parties hereto acknowledge that the Self
            -----------------
Tender Offer is an integral part of the Reorganization Agreement and the Board
of Directors, of Tyrex approved such Agreement based upon the representations,
warranties and covenants of Richardson and of 3Si and the 3Si Shareholders as to
its and their ability to provide the information necessary to meet the filing
requirements described in paragraph 3 above.  Therefore, the Parties agree that:
            (i)   all will use their respective best efforts to conclude the
     Property Sale and if such is not concluded, each will use their respective
     best efforts to conclude a sale of the properties included in the present
     Agreement to another party as soon as is reasonably practicable:

            (ii)   proceeds from the Property Sale, after payment of certain
     liabilities contemplated in the Reorganization Agreement, will be
     segregated and deposited in a trust escrow account with trust escrow
     account shall be Tom N. Richardson, John D. Traut and William P. Gruman and
     that a majority vote of the three trustees will be necessary for the trust
     to take any action to fulfill its purposes;

          (iii)     the proceeds from the Property Sale, as deposited in the
     trust escrow account, along with funds from the Tyrex general account shall
     equal $1,800,000 plus an additional amount estimated to be sufficient to
     cover the legal, accounting, printing, mailing and other reasonable costs
     associated with the Self Tender Offer and will be held in trust for the
     benefit of existing Tyrex shareholders and shall not be subject to claims
     of creditors of 3Si nor shall it be subject to satisfying any actions or
     claims against 3Si;

          (iv)   3Si and the 3Si Shareholders, individually, for and in
     consideration of the sum of $10.00 each, the receipt of which is hereby
     acknowledged, hereby waive and reject any right to Participate in the Self
     Tender Offer described herein and in the Reorganization Agreement;

          (v)  the Parties hereto acknowledge that the Self Tender Offer will
     consist of offers to all Tyrex shareholders as of a record date after the
     Closing Date set forth in the Reorganization Agreement (excluding the three
     current 3Si shareholders) and in general terms, such tender offer shall be
     for approximately 6,000,000 shares of Tyrex Common Stock at approximately
     $.30 per share or a total of approximately $1,800,000, It is understood
     that the number of shares and price per share may be adjusted to reflect
     market or other conditions as determined in the sole discretion of the
     Tyrex Board of Directors.  It is further contemplated that shareholders
     will be allowed to tender none, a portion, or all of their shares (subject
     to proration);

          (vi)      if, for any reason, regulatory requirements or Securities
     and Exchange Commission rules and regulations require, the Parties hereto
     agree to modify this Agreement, to whatever extent is necessary to carry
     out the full intent and purpose of the Self Tender Offer;

          (vii)     in the event that, for any reason, a shareholder vote shall
     be required to effect modifications contemplated in (vi) above, Richardson
     and the 3Si Shareholders agree to vote their shares in favor thereof; and

                                       4
