                        AMENDMENT TO EMPLOYMENT AGREEMENT

THIS AMENDMENT TO EMPLOYMENT AGREEMENT is entered into this 12th day of May,
1999, between BASIN EXPLORATION, INC., a Delaware corporation (the
"Corporation"), and PATRICK A. JACKSON (the "Officer").

         The Corporation and the Officer have previously entered into an
Employment Agreement dated as of January 28, 1999 (the "Employment Agreement")
and desire to amend the Employment Agreement to clarify certain provisions
regarding compensation payable to the Officer in the event of a Change of
Control as defined in the Employment Agreement.

         NOW, THEREFORE, in consideration of the premises and for good and
valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, the parties agree as follows:

         1.       DEFINED TERMS. All terms used and not defined herein shall
have the meaning given them in the Employment Agreement.

         2.       DELETION OF SECTION 2.7(c). Section 2.7(c) of the Employment
Agreement is deleted.

         3.       LIMITATION ON AMOUNT OF PAYMENT. A new Section 4.1(f) is added
to the Employment Agreement to read as follows:

         (f)      LIMITATION OF CHANGE OF CONTROL PAYMENTS.

                  (i)      Notwithstanding anything else in this Agreement,
                           solely in the event of a termination by the
                           Corporation without Cause or a termination by the
                           Officer for Good Reason, and except as provided in
                           subsection (a) below, the aggregate of the payments
                           of benefits to which the Officer will be entitled
                           under Section 4.1(c) will be reduced to the extent
                           necessary so that the Officer will not be liable for
                           the federal excise tax levied on certain "excess
                           parachute payments" under section 4999 of the
                           Internal Revenue Code.

                                    (a) The limitation of Section 4.1(f)(i) will
                                    not apply if the difference between (w) the
                                    present value of all payments to which the
                                    Officer is entitled under Section 4.1(c)
                                    determined without regard to Section
                                    4.1(f)(i) less (x) the present value of all
                                    federal, state and other income and excise
                                    taxes for which the Officer is liable as a
                                    result of such payments exceeds the
                                    difference between (y) the present value of
                                    all payments to which the Officer is
                                    entitled under Section 4.1(c) calculated as
                                    if the limitation of Section

<PAGE>

                                    4.1(f)(i) applies less (z) the present value
                                    of all federal, state and other income and
                                    excise taxes for which the Officer is liable
                                    as a result of such reduced payments.
                                    Present values will be determined using the
                                    interest rate specified in section 280G of
                                    the Internal Revenue Code and will be the
                                    present values as of the date on which the
                                    Officer's employment terminates (unless it
                                    is necessary to use a different date in
                                    order to avoid adverse consequences under
                                    section 280G).

                  (ii)     DETERMINATION BY OFFICER. Whether payments to the
                           Officer are to be reduced pursuant to Section
                           4.1(f)(i), and the extent to which they are to be so
                           reduced, will be determined by the Officer. The
                           Officer may, at the expense of the Company, hire an
                           accounting firm, law firm or employment consulting
                           firm selected by the Officer to assist him in such
                           determination. If a reduction is made pursuant to
                           Section 4.1(f)(i), the Officer will have the right to
                           determine which payments and benefits will be
                           reduced.

                  (iii)    ADDITIONAL BENEFIT. The Officer shall receive the
                           benefit of any change made by the Corporation in the
                           calculation or entitlement of severance compensation
                           following a Change of Control for any other officer
                           of the Corporation, such as an agreement by the
                           Corporation to "gross up" the compensation paid to an
                           officer by paying the excise tax imposed by Section
                           280G of the Internal Revenue Code .

         4.       EFFECT OF AMENDMENT. As amended hereby, the Employment
Agreement remains in full force and effect.

         IN WITNESS WHEREOF, the parties have executed this Amendment to
Employment Agreement on the day and year first above entered.

III.  STATUS OF SECURITIES.

      SECTION 3.01 SECURITIES OF ACHIEVEMENT TEC.

      (a) The shares of Achievement Tec Common Stock outstanding at the
Effective Time, together with the shares of Achievement Tec Common Stock
issuable upon the conversion of shares of Achievement Tec Preferred Stock,
shall, subject to Section 3.01(e), be converted into and exchanged for an
aggregate of 7,000,000 shares of SRM Common Stock, representing 70% of the total
issued and outstanding shares of SRM Common Stock immediately following the
Effective Time.

      (b) Notwithstanding Section 3.01(a), no share of SRM Common Stock shall be

by such New Certificates; and (ii) the amount, without interest, of dividends
and liquidating or other distributions, if any, payable to record holders of
Achievement Tec Common Stock prior to the Effective Time, as declared by the
Board of Directors of Achievement Tec.

      If outstanding Old Certificates are not surrendered and exchanged for New
Certificates prior to two years after the Effective Time (or the date prior
thereto when the whole shares of SRM Common Stock, the dividends and liquidating
or other distributions, if any, and cash in lieu of fractional shares described
below would otherwise escheat to, or become the property of, any governmental
unit or any agency thereof): (i) the number of whole shares of SRM Common Stock
for which the shares of Achievement Tec Common Stock represented by such Old
Certificates shall have been converted; (ii) the amount of dividends and

amount of dividends and liquidating or other distributions, if any, declared by
the Board of Directors of Achievement Tec and payable to the record holders of
Achievement Tec Common Stock at any time prior to the Effective Time, but
payable subsequent thereto; and (iv) the amount of dividends and liquidating or
other distributions, if any, which subsequently become payable with respect to
such number of whole shares of SRM Common Stock, shall become the property of
SRM (and, to the extent not in its possession, shall be paid over to it), free
and clear of all claims or interest of any other person previously entitled
thereto.

      (d) If any New Certificate is to be issued in a name other than that in
which the Old Certificate surrendered for exchange is issued, such Old
Certificate shall be properly endorsed and otherwise in proper form for transfer
and the person requesting such exchange shall pay to SRM any transfer or other
taxes required by reason of the issuance of the New Certificate in any name
other than that of the registered holder of the surrendered Old Certificate, or
establish to the satisfaction of SRM that such tax has been paid or is not
payable.

      (e) As of the Effective Time, no transfer of the shares of Achievement Tec
Common Stock outstanding prior to the Effective Time shall be made on the stock
transfer books of the Surviving Corporation. If, after the Effective Time, Old

<PAGE>

                  (i) There has at no time been a material adverse change in the
            financial condition, results of operations, businesses, properties,
            assets, liabilities, or future prospects of SRM and Acquisition,
            taken as a whole.

                  (ii) Neither SRM nor Acquisition has authorized, declared,
            paid, or effected any dividend or liquidating or other distribution
            in respect of its capital stock or any direct or indirect
            redemption, purchase, other acquisition, combination, split, or
            reorganization of any stock of either of them.

                  (iii) The operations and businesses of SRM and Acquisition
            have been conducted in all respects only in the ordinary course,
            except for (A) the issuance and sale of shares of SRM Common Stock
            to designees of NIR and (B) the reincorporation merger of SRM from
            the State of Idaho to the State of Delaware and the amendment of the

            loss (whether or not covered by insurance) or waived any right of
            substantial value. There is no fact known to SRM or Acquisition
            which materially adversely affects, or in the future (as far as
            either SRM or Acquisition can foresee) may materially adversely
            affect the financial condition, results of operations, businesses,
            properties, assets, liabilities, or future prospects of SRM or
            Acquisition, or, after the Merger, the Surviving Corporation;
            provided, however, that neither SRM nor Acquisition expresses any
            opinion as to political or economic matters of general
            applicability.

            (d) Each of SRM and Acquisition has filed, or as of the Effective

authorities all Tax Returns required

                                      -11-
<PAGE>

to be filed by or with respect to SRM or Acquisition whose due dates (taking
into account any timely filed extensions) fall on or before the Effective Time,
and such Tax Returns are or will be true, correct, and complete in all material
respects and disclose all Taxes required to be paid by SRM or Acquisition,
respectively. Each of SRM has paid in full or has made adequate provision in the
Last SRM Balance Sheet for all Taxes which are or will be due or claimed to be
due from it by any authority for all periods or portions thereof up to and
including the Effective Time. There are no liens for Taxes upon the assets of
SRM or Acquisition, except for statutory liens for current Taxes not yet due.
Neither SRM nor Acquisition has (i) requested any extension of time within which

waived any statute of limitations for, or agreed to any extension of time with
respect to, the assessment of Taxes thereof. No claim has ever been made by an
authority in a jurisdiction where either SRM or Acquisition does not file Tax
Returns that it is or may be subject to taxation by that jurisdiction. Each of
SRM and Acquisition has delivered to Achievement Tec true, correct, and complete
copies of all federal income Tax Returns, examinations, reports, and statements
of deficiencies assessed against, or agreed to by, it since December 31, 1994.
Neither SRM nor Acquisition has received any notice of deficiency or assessment
from any federal, state, local, or foreign taxing authority with respect to
liabilities for Taxes thereof which have not been fully paid or finally settled,
and, to the knowledge of SRM and Acquisition, there are no existing or prior
facts, circumstances, or conditions that would form the basis for such a notice
of deficiency or assessment. Neither SRM nor Acquisition is a party to a tax
sharing or tax indemnity agreement or any other agreement of a similar nature
that remains in effect. Neither SRM nor Acquisition has been a United States
real property holding corporation within the meaning of Section 897(c)(2) of the

or has any liability for the Taxes of any person under Treasury Regulation
1.1502-6 (or any similar provision of state, local, or foreign law) as a
transferee, or successor, by contract or otherwise.

            (e) There is no litigation, arbitration, claim, governmental or
other proceeding (formal or informal), or investigation pending, threatened, or
in prospect (or any basis therefor known to SRM) with respect to SRM or
Acquisition or any of its respective businesses, properties, or assets. Neither
SRM nor Acquisition is in violation of, or in default with respect to, any law,
rule, regulation, order, judgment, or decree; nor is SRM or Acquisition required
to take any action in order to avoid such violation or default. There is no

which has had, or may in the future have, a material adverse effect on the
respective financial condition, results of operations, businesses, properties,
assets, liabilities, or future prospects of SRM or Acquisition, or, after the
Merger, of the Surviving Corporation. Notwithstanding this Agreement and related

any contract, agreement, instrument, lease, license, arrangement, or
understanding with any stockholder, director, officer, or employee of SRM or
Acquisition or any relative or affiliate of any stockholder, director, officer,
or employee, of SRM or Acquisition or any other corporation or enterprise in
which any stockholder of SRM or Acquisition, any such director, officer, or
employee, or any such relative or affiliate then had or now has a 5% or greater
equity or voting or other substantial interest. The stock ledgers, stock
transfer books, and the minute book records of each of SRM and Acquisition and
any other document provided by SRM relating to all issuances and transfers of
stock and all proceedings of the stockholders and the Board of Directors and
committees thereof since their respective incorporations, all of which have been

Neither SRM nor Acquisition is in violation, breach, or in default with respect
to any term of its respective certificate of incorporation (or other charter

            (j) Each of SRM and Acquisition has all requisite power and
authority to execute, deliver, and perform this Agreement and the other
transactions contemplated by, and in connection with, this Agreement. All
necessary corporate proceedings of SRM and Acquisition have been duly taken to
authorize the execution, delivery, and performance of this Agreement and the
other transactions contemplated by, and in connection with, this Agreement. This
Agreement has been duly authorized, executed, and delivered by each of SRM and
Acquisition, constitutes the legal, valid, and binding obligation of each of SRM
and Acquisition, and is enforceable as to each of SRM and Acquisition in
accordance with its terms. No consent, authorization, approval, order, license,
certificate, or permit of or from, or declaration or filing with, any federal,
state, local, or other governmental authority or any court or other tribunal is
required by SRM or Acquisition for the execution, delivery, or performance of
this Agreement. No consent of any party to any contract, agreement, instrument,
lease, license, arrangement, or understanding to which SRM or Acquisition is a
party, or to which it or any of its respective properties or assets are subject,
is required for the execution, delivery, or performance of this Agreement and
the execution, delivery, and performance of this Agreement, will not violate,
result in a breach of, conflict with, or (with or without the giving of notice
or the passage of time or both) entitle any party to terminate or call a default
under, receive rights or privileges that such party was not entitled to receive
before, this Agreement and the other transactions contemplated by, and in
connection with, this Agreement was executed under, or create

                                      -15-
<PAGE>

any obligation on the part of either SRM or Acquisition to which such
corporation was not subject immediately before this Agreement was executed
under, any term of any such contract, agreement, instrument, lease, license,
arrangement, or understanding, or violate or breach their respective
certificates of incorporation (or other charter document) or by-laws, or
violate, result in a breach of, or conflict with any law, rule, regulation,
order, judgment, or decree binding on SRM or Acquisition or to which any of
their respective businesses, properties, or assets are subject. Neither SRM nor
Acquisition, nor any of their respective officers, directors, employees, or
agents has employed any broker or finder or incurred any liability for any fee,
commission, or other compensation payable by any person on account of alleged
employment as a broker or finder, or alleged performance of services as a broker

the other transactions contemplated by this Agreement.

            (k) No representation or warranty by SRM or Acquisition in this
Agreement contains, or at the Effective Time will contain, an untrue statement
of material fact or omits, or at the Effective Time will omit, to state a
material fact required to be stated therein or necessary to make the statements

and are in accordance with the books and records of Achievement Tec. Since the

                  (i) There has at no time been a material adverse change in the
            financial condition, results of operations, businesses, properties,
            assets, liabilities, or future prospects of Achievement Tec.

                  (ii) Achievement Tec has not authorized, declared, paid, or
            effected any dividend or liquidating or other distribution in
            respect of its capital stock or any direct or indirect redemption,
            purchase, other acquisition, combination, split, or reorganization
            of any stock of Achievement Tec.

                  (iii) The operations and businesses of Achievement Tec have

            (whether or not covered by insurance) or waived any right of

            materially adversely affects, or in the future (as far as
            Achievement Tec can reasonably foresee) may materially adversely
            affect the financial condition, results of operations, businesses,
            properties, assets, liabilities, or future prospects of Achievement
            Tec or, after the Merger, the Surviving Corporation; provided,
            however, that Achievement Tec expresses no opinion as to political
            or economic matters of general applicability.

filed, with the appropriate federal, state, local and foreign tax authorities
all Tax Returns required to be filed by or with respect to Achievement Tec whose
due dates (taking into account any timely filed extensions) fall on or before
the Effective Time, and such Tax Returns are or will be true, correct, and
complete and disclose all Taxes required to be paid by Achievement Tec.
Achievement Tec has paid in full or has made adequate provision in the Last

authority in a jurisdiction where Achievement Tec does not file Tax Returns that
it is or may be subject to taxation by that jurisdiction. Achievement Tec has
delivered to SRM and Acquisition true, correct, and complete copies of all
federal income Tax Returns, examinations, reports, and statements of
deficiencies assessed against or agreed to by it since December 31, 1994.
Achievement Tec has not received any notice of deficiency or assessment from any
federal, state, local, or foreign taxing authority with respect to liabilities

and, to the knowledge of Achievement Tec, there are no existing or prior facts,
circumstances, or conditions that would form the basis for such a notice of
deficiency or assessment. Achievement Tec is not a party to a tax sharing or tax
indemnity agreement or any other agreement of a similar nature that remains in
effect. Achievement Tec has not been a United States real property holding
corporation within the meaning of Section 897(c)(2)

otherwise.

            (e) There is no litigation, arbitration, claim, governmental or
other proceeding (formal or informal), or, to Achievement Tec's knowledge,

Achievement Tec as collective bargaining agent. To Achievement Tec's knowledge,
Achievement Tec is not in violation of, or in default with respect to, any law,
rule, regulation, order, judgment, or decree which violation or default would
have a material adverse effect on the business, prospects, financial condition,
or results of operations of Achievement Tec; nor is Achievement Tec required to
take any action in order to avoid such violation or default.

knowledge and which (if existing and known at the date of the execution of this
Agreement) would have been required to be set forth or disclosed in or pursuant

Time, Acquisition will conduct no affairs, except in connection with this
Agreement, the Merger, or any of the other transactions contemplated by this

foregoing, any prescribed periods within which a "blue-sky" or securities law

Effective Time.

            (g) The parties to this Agreement shall have obtained at or prior to
the Effective Time all consents required for the consummation of the Merger and
the other transactions contemplated by this Agreement from any party to any
contract, agreement, instrument, lease, license, arrangement, or understanding
to which any of them is a party, or to which any of them or any of their
respective businesses, properties, or assets are subject.

            (h) Prior to the Effective Time, Achievement Tec shall conduct a due
diligence review of SRM and Acquisition and shall be reasonably satisfied with
the results of such review.

            (i) SRM shall have consummated the sale of shares of SRM Common
Stock referred to in Section 7.01(j).

      SECTION 8.03 ADDITIONAL TERMS OF ABANDONMENT.

      In addition to the provisions of Section 8.01 and 8.02, the Merger may be

contemplated hereby by the stockholders of Acquisition and Achievement Tec:

                  (i) by mutual agreement of the Boards of Directors of SRM,
Acquisition, and Achievement Tec;

                  (ii) at the option of SRM's and Acquisition's Boards of
Directors or Achievement Tec's Board of Directors, if the Effective Time shall
not have occurred on or before May 31, 2000;

                  (iii) at the option of SRM's and Acquisition's Boards of
Directors, if facts exist which render impossible compliance with one or more of
the conditions set forth in Section 8.01 and such are not waived by Achievement
Tec; and

                  (iv) at the option of Achievement Tec's Board of Directors, if
facts exist which render impossible compliance with one or more of the
conditions set forth in Section 8.02 and such are not waived by SRM and
Acquisition.

      SECTION 8.04 EFFECT OF ABANDONMENT.

            If the Merger is rightfully abandoned or terminated as provided for
in Article VII or in this Article VIII:

            (a) except for Sections 7.01(i), 7.02(k), and 8.04(b), this
Agreement shall become wholly void and of no further force or effect without
liability on the part of either party to this Agreement or on the part of any
officer, director, controlling person (if any), employee, counsel, agent, or
stockholder thereof; provided, however, that nothing in this Section 8.04(a)
shall release SRM, Acquisition, or Achievement Tec or any officer, director,
controlling person (if any), employee, counsel, agent, or stockholder thereof
from liability for a willful failure to carry out its respective obligations
under this Agreement; and

            (b) each of SRM, Acquisition, and Achievement Tec shall pay and bear
its own fees and expenses incident to the negotiation, preparation, and
execution of this Agreement and its

                                      -37-

meeting of stockholders (if required), including fees and expenses of its
counsel, accountants, and other experts.

provisions of this Agreement could not adequately be compensated by money
damages, any party shall be entitled, in addition to any other right or remedy
available to it, to an injunction restraining such breach or threatened breach
and to specific performance of any such provision of this Agreement, and no bond
or other security shall be required in connection therewith, and the parties
hereby consent to the issuance of such an injunction and to the ordering of
specific performance.

      SECTION 9.03 SURVIVAL. Each of the covenants, agreements, representations,
and warranties contained in this Agreement shall survive the Effective Time. The

connection with the transactions contemplated hereby or thereby, or in any
statement, certificate, or other instrument delivered by, or on behalf of,
Achievement Tec pursuant hereto or thereto or delivered to either SRM or
Acquisition in connection with the transactions contemplated hereby or thereby
shall be deemed representations and warranties, covenants and agreements, or
conditions, as the case may be, of Achievement Tec hereunder for all purposes of

      SECTION 9.04 ENTIRE AGREEMENT; MODIFICATION. This Agreement sets forth the
entire understanding of the parties with respect to the subject matter hereof
(except as provided in Section 9.03), supersedes all existing agreements among
them concerning such subject matter, and may be modified only by a written
instrument duly executed by each party hereto.

      SECTION 9.05 NOTICES. Any notice or other communication required or
permitted to be given hereunder shall be in writing and shall be mailed by
certified mail, return receipt requested or by the most nearly comparable method

delivered (in person or by telecopy, telex, or similar telecommunications
equipment) against receipt to the party to which it is to be given at the

comparable method) shall be deemed given at the time of certification thereof

be deemed given at the time of receipt thereof. Any notice given by other means
permitted by this Section 9.05 shall be deemed given at the time of receipt
thereof.

      SECTION 9.06 WAIVER. Any waiver by any party of a breach of any term of
this Agreement shall not operate as, or be construed to be, a waiver of any
other breach of that term or of any breach of any other term of this Agreement.
The failure of a party to insist upon strict adherence to any term of this
Agreement on one or more occasions will not be considered a waiver or deprive
that party of the right thereafter to insist upon strict adherence to that term
or any other term of this Agreement. Any waiver must be in writing and be
authorized by a resolution of the Board of Directors or by a duly authorized
officer of the waiving party.

      SECTION 9.07. BINDING EFFECT. The provisions of this Agreement shall be

hereto shall have the right to assign its rights and obligations hereunder
without the prior written consent of the other parties hereto.

      SECTION 9.08 NO THIRD-PARTY BENEFICIARIES. This Agreement does not create,
and shall not be construed as creating, any rights enforceable by any person not
a party to this Agreement, except as provided in Section 9.07, except for the
indemnitees referenced in Sections 7.01(I) and 7.02(k) hereof.

      SECTION 9.09 SEPARABILITY. If any provision of this Agreement is invalid,
illegal, or unenforceable, the balance of this Agreement shall remain in effect,
and if any provision is inapplicable to any person or circumstance, it shall
nevertheless remain applicable to all other persons and circumstances.

                          AGREEMENT AND PLAN OF MERGER

      THIS ADDENDUM TO AGREEMENT AND PLAN OF MERGER (hereinafter the
"Addendum"), is made and entered into as of the first day of July, 2000, by and
among SILVER RAMONA MINING COMPANY, a Delaware corporation (hereinafter "SRM");
ACHIEVEMENT TECH ACQUISITION, INC., a Delaware corporation and a wholly-owned
subsidiary of SRM; and ACHIEVEMENT TEC, INC., a Texas corporation (hereinafter
"Achievement Tec"); and is intended to amend that certain Agreement and Plan of
Merger executed by the parties hereto on May 9, 2000 (the "Merger Agreement").

                                    RECITALS:

      WHEREAS, the parties hereto desire to amend the Merger Agreement and add
the terms and conditions contained herein; and

      WHEREAS, the parties hereto desire that all other terms and conditions of
the Merger Agreement not specifically amended hereby shall remain in full force
and effect.

      NOW, THEREFORE, in consideration of the premises herein contained, the
parties hereby agree as follows:

      1. The parties hereto agree that the Merger Agreement shall be amended to
provide that consummation of the Merger and the other transactions contemplated
by the Merger Agreement shall be contingent upon the following provision:

      Immediately prior to the Effective Time (as defined in Article
      IV of the Merger Agreement), Achievement Tec will have received
      the aggregate sum of THREE HUNDRED THOUSAND DOLLARS ($300,000)
      in financing, $200,000 of which shall be for pre-merger capital
      stock of Achievement Tec and $100,000 of which shall be in
      consideration of the issuance of a promissory note or notes by
      Achievement Tec in the aggregate principal amount of $100,000.
      Such funds will be in cash or cash equivalent and are to be used
      for the general corporate and working capital purposes of
      Achievement Tec, which, pursuant to the terms of the Merger
      Agreement, shall be a wholly-owned subsidiary of SRM following
      the Effective Time. At the time the funds are deposited with
      Achievement Tec, a separate document will be delivered to SRM
      giving a summary of the intended use of proceeds and the amount
      to be designated for each use. If the $300,000 is not deposited
      with Achievement Tec at the time of the proposed Effective Time,
      the Merger Agreement shall be deemed to be terminated.

      2. All other provisions, terms and conditions of the Merger Agreement
shall remain in full force and effect and shall not be altered or amended except
as otherwise provided herein.

      3. All capitalized terms used, but not otherwise defined, herein, shall
have the respective meanings ascribed to them in the Merger Agreement.

      4. This Addendum shall be governed by, and construed in accordance with,
the laws of the State of New York, without regard to its conflicts of laws
principles.

      5. This Addendum may be executed in one or more counterparts, each such
counterpart to be deemed an original instrument, but all of which such
counterparts together shall constitute but one agreement.

      6. This Addendum may not be modified or amended, nor any provision hereof
waived, by any party, except by a writing executed by each of the parties
hereto.

              [THE REMAINDER OF THIS PAGE INTENTIONALLY LEFT BLANK]

      IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Addendum to Agreement and Plan of Merger in a manner legally binding upon them
