Consideration") to be paid by Amerac for all of the issued and outstanding
Ridgepointe Common Stock and all of the issued and outstanding Fremont Common
Stock not owned by Ridgepointe (collectively, the "Purchased Stock") shall be
$7,640,000.00, consisting of an aggregate of (a) that number of shares of common
stock, par value $.05 per share, of Amerac ("Amerac Common Stock") with a value
equal to $640,000.00 based upon the average of the closing prices in the over-
the-counter market as reported by the National Quotation Bureau, Incorporated,
for Amerac Common Stock during the thirty (30) Business Days (as defined
hereinafter) immediately preceding the fifth (5th) Business Day prior to the
Closing Date (as defined in Section 1.10) (the "Amerac Shares"), and (b)
$7,000,000.00 in cash (the "Initial Cash Amount").  The Initial Purchase
Consideration shall be subject to adjustment in accordance with the provisions
of Section 1.5, and as so adjusted, shall be referred to hereinafter as the
"Adjusted Purchase Consideration."  For purposes of this Agreement, the term
"Business Days" means any day on which the New York Stock Exchange is open for
trading.

     1.3  Deposit.  Concurrently with the execution of this Agreement, Amerac
has deposited in escrow with Bank One, Texas, National Association ("Bank"), as
escrow agent, pursuant to an Escrow Agreement in the form attached hereto as
Exhibit B, the sum of $350,000.00, such sum representing five percent (5%) of
the Initial Cash Amount (the "Deposit").  Subject to the provisions of this
Section 1.3, following the Closing, all or a portion of the Deposit may be
retained in escrow and applied and disbursed in accordance with the provisions
of Sections 2.3, 2.4, and/or 2.7, as applicable.  To the extent that any portion
of the Deposit is not thus retained in escrow at the Closing, such portion of
the Deposit shall be applied to the payment of the Adjusted Purchase
Consideration at the Closing.  If this Agreement is terminated, other than by
reason of a breach of this Agreement by Amerac, Amerac and the Selling
Shareholders shall deliver to Bank a written notice instructing Bank to pay to
Amerac the Deposit, plus all accrued interest thereon.  If the Selling
Shareholders believe that Amerac has breached this Agreement, and such breach is
grounds for termination in accordance with the provisions hereof, the Selling
Shareholders shall provide to Amerac written notice setting forth the
particulars of the alleged breach.  If Amerac is unable to remedy the alleged
breach, and the Selling Shareholders elect to terminate this Agreement as the
result thereof, Amerac and the Selling Shareholders shall deliver to Bank a
joint notice instructing Bank to pay to the Selling Shareholders the Deposit,
plus all accrued interest thereon; provided, however, that if Amerac disputes
the alleged breach, the Selling Shareholders and Amerac shall submit such
dispute to arbitration in accordance with the procedures set forth in Section
2.8.  If such a dispute is submitted to arbitration, Amerac and the Selling
Shareholders, or either of them, shall provide to Bank written notice of such
fact that identifies the nature of the dispute and the arbitrator selected and
that instructs Bank to disburse the Deposit and all accrued interest thereon in
accordance with instructions to be delivered to Bank by the arbitrator following
the issuance of the arbitrator's decision.  Any such notice delivered
unilaterally by Amerac or the Selling Shareholders shall also be delivered to
the other party, and proof of the delivery of such notice shall be provided to
Bank.

     1.4  Intercompany Transactions.  The Selling Shareholders shall cause all
intercompany loan accounts and accounts receivable between the Selling
Shareholders and any of their respective parents, subsidiaries, or other
affiliates, on the one hand, and Fremont and

                                       2

receivable owed to Fremont as to which Fremont Exploration, Inc. ("FEI"), is the
account debtor), to be settled immediately prior to the Closing.  In addition,
immediately prior to the Closing, the Selling Shareholders shall cause:  (a)

reflected in Section II of Schedule 1.01 under the caption "Current Ownership,"
to Powell and Thomas O. Goldsworthy, in the proportions of fifty percent (50%)

later than three (3) Business Days prior to the Closing, the Selling
Shareholders shall provide to Amerac documentation reflecting the full payment
and/or cancellation of all such intercompany accounts and the consummation of
all such transactions.

     1.6  Preliminary Settlement Statement.  Not less than three (3) Business
Days prior to the Closing, the Selling Shareholders shall prepare and submit to
Amerac for review a draft settlement statement (the "Preliminary Settlement
Statement") that shall set forth each estimated adjustment to be made to the
Initial Cash Amount in accordance with Section 1.5 based upon information
available as of the date of preparation of such Preliminary Settlement
Statement, and calculate the preliminary Adjusted Purchase Consideration to be
paid at Closing.  In addition, the Preliminary Settlement Statement shall also
set forth the amounts to be placed in escrow as the result of the existence of
any uncured Defects pursuant to Section 2.4, any unremediated Environmental
Claims pursuant to Section 2.3, and any unrepaired Casualty pursuant to Section
2.7, and the Evaluated Interests (as defined in Section 2.1(b)) affected thereby
(if any).  The Preliminary Settlement Statement shall also contain a written
designation of the accounts into which the wire transfers of funds to each
Selling Shareholder provided for below in Section 1.10 are to be made.

     1.7  Final Accounting.  As soon as practicable following the Closing, but

                                       5
<PAGE>
 
settlement statement which takes into account all final adjustments made to the
Initial Cash Amount and which calculates the final Adjusted Purchase
Consideration (the "Final Settlement Statement").  After taking into account
disbursements of any funds held in escrow pursuant to Sections 2.3, 2.4, or 2.7,
(a) if the final Adjusted Purchase Consideration reflected in the Final
Settlement Statement exceeds the preliminary Adjusted Purchase Consideration
reflected in the Preliminary Settlement Statement, Amerac shall pay any such
difference to the Selling Shareholders; and (b) if the final Adjusted Purchase
Consideration reflected on the Final Settlement Statement is less than the
preliminary Adjusted Purchase Consideration reflected in the Preliminary
Settlement Statement, the Selling Shareholders shall pay any such difference to
Amerac.  All disbursements to and payments by the Selling Shareholders pursuant
to this Section 1.7 shall be made on the same proportionate basis as the amounts
paid under Section 1.10 below.  If the Selling Shareholders and Amerac are
unable to agree on the Final Settlement Statement on or before thirty (30) days
after the receipt thereof by the Selling Shareholders, Amerac and the Selling
Shareholders shall submit all unresolved claims and amounts to arbitration in
accordance with the provisions of Section 2.8.  Following the issuance of the
arbitrator's decision, Amerac and the Selling Shareholders shall pay each to the
other such amounts as are required to be paid, respectively, by such parties
under the terms of such arbitrator's decision.

     1.8  No Registration; Legends.  The issuance of the Amerac Shares in
connection with the Purchase will not be registered under the Securities Act of
1933, as amended (the "1933 Act"), and thus such shares will be "restricted
securities" as such term is defined under Rule 144 under the 1933 Act.  Each
certificate representing the Amerac Shares shall bear the legend set forth in
Exhibit C hereto with respect to such matters.  In addition, at the Closing,
Amerac and the Selling Shareholders shall execute a Registration Rights
Agreement in the form attached hereto as Exhibit J.

     1.9  Power of Attorney and Custody Agreement.  Concurrently with the
execution of this Agreement, each Other Selling Shareholder and the Partnership
has placed certificates representing the shares of Ridgepointe Common Stock to
be sold by such Other Selling Shareholder and the Partnership pursuant to this
Agreement in custody, for delivery under this Agreement, under a Custody
Agreement made with Thomas O. Goldsworthy substantially in the form of Exhibit D
hereto, and an Amended and Restated Power of Attorney appointing Thomas O.
Goldsworthy and V. Lee Powell as agents and attorneys-in-fact for such Other
Selling Shareholder and the Partnership.  The form of the Amended and Restated
Power of Attorney is set forth in Exhibit E hereto.

     1.10 Closing.  The closing of the Purchase contemplated hereby (the
"Closing") shall be held at the offices of Jackson & Walker, L.L.P., 1100
Louisiana, Suite 4200, Houston, Texas 77002 at 10:00 a.m., Houston time, on
January 15, 1995, or at such other place or time as Amerac and the Selling
Shareholders may mutually agree.  The date of the Closing is referred to herein
as the "Closing Date."  Upon the terms and subject to the conditions of this
Agreement, at the Closing, each Selling Shareholder will deliver to Amerac
certificates representing the number of shares of the Purchased Stock set forth
opposite each such Selling Shareholder's name in Sections I and II of Schedule
1.01, together with stock powers executed in blank, and Amerac shall pay to the
Selling Shareholders, in the proportions set out in Section

                                       6
<PAGE>
 
III of Schedule 1.01, the preliminary Adjusted Purchase Consideration as
reflected in the Preliminary Settlement Statement.  Amerac shall pay the cash
portion of such preliminary Adjusted Purchase Consideration to the Selling
Shareholders by bank wire transfer of immediately available funds from, first,
the funds constituting the Deposit that are not being held in escrow following
the Closing in accordance with Sections 2.3, 2.4, and 2.7, and, second, Amerac's
designated account at Bank.  Each of the Selling Shareholders and Amerac shall
deliver such other documents and instruments, and shall take such other and
further actions, as are required under the terms of this Agreement in connection
with the consummation of the transactions contemplated herein.

     1.11 Certification Under Treasury Regulations.  At the Closing, each
Selling Shareholder will provide to Amerac a statement which satisfies the
requirements of Treas. Reg. (S) 1.1445-2(b)(2) certifying that such Selling
Shareholder is not a "foreign person."

     1.12 Allocated Values.  For purposes of this Agreement, with respect to
each Evaluated Interest, the term "Allocated Value" means the amount set forth
on Exhibit A under the column "Allocated Value" for such Evaluated Interest.
The Selling Shareholders and Amerac agree and stipulate that the Allocated
Values set forth for the Evaluated Interests in Exhibit A have been established
solely for use in calculating adjustments to the Initial Purchase Consideration
as provided herein, such schedule of Allocated Values being solely for the
convenience of the parties.  The Selling Shareholders and Amerac do not intend
that such schedule of Allocated Values be treated or interpreted to constitute
an allocation of the Purchase Consideration among the Evaluated Interests for
federal or state income tax purposes.

                                       10

          (xiii)  all other Liens, charges, encumbrances, contracts, agreements,
instruments, obligations, defects, and irregularities affecting the Evaluated
Interests relating to obligations not yet in default, which individually or in
the aggregate are not such as to interfere materially with the operation, value,
or use of any Evaluated Interest, do not materially prevent Amerac from
receiving the proceeds of production from any Evaluated Interest, do not reduce
the net revenue interest of Fremont in any Evaluated Interest to less than the
"Net Revenue Interest" set forth for such Evaluated Interest on Exhibit A and do
not obligate Fremont to bear costs and expenses relating to the maintenance,
development, and operation of any Evaluated Interest in any amount greater than
the "Working Interest" set forth for such Evaluated Interest on Exhibit A
(unless the actual net revenue interest of Fremont in such Evaluated Interest is
greater than the "Net Revenue Interest" set forth therefor on Exhibit A in the
same proportion as any increase in such "Working Interest").

     2.2  Access.  Through the Closing Date, the Selling Shareholders shall
cause Fremont and Ridgepointe to give Amerac and its representatives (including
Amerac's employees, consultants, independent contractors, attorneys,
accountants, and other advisors) full access during normal business hours to all
of the offices, personnel, books, files, records, contracts, correspondence,
computer output, data files (to the extent Fremont and/or Ridgepointe have the
right to make the same available), maps, reports, plats, and other documents of
Fremont and Ridgepointe, or to which Fremont or Ridgepointe have access,
pertaining to any of their respective properties and assets, including, without
limitation, all abstracts of title, title opinions, title curative materials,
lease files, contract files, division order files, operations records,
environmental records, production records, facility and well files and records,
regulatory agency files, hydrocarbon marketing files, accounting records
(including, without limitation, records relating to gas imbalances and suspense
items), geological, geophysical, and other scientific and technical data and
information, and other information, data, records, and files which Fremont
and/or Ridgepointe may have (or have access to) relating in any way to the Oil
and Gas Properties and the other properties and assets of such parties, the past
or present operation thereof, and the marketing of hydrocarbon production
therefrom.  Amerac shall have the right to photocopy such materials at Amerac's
expense.  If Amerac requests information not in the possession of Fremont and/or
Ridgepointe, the Selling Shareholders shall cause Fremont or Ridgepointe, as
applicable, to use all reasonable efforts to obtain the requested information
from the applicable operators and other third parties.  Through the Closing
Date, the Selling Shareholders shall also cause Fremont and Ridgepointe to
afford Amerac and its authorized representatives reasonable access to and entry
upon all of the Oil and Gas Properties and all of such parties' other properties
and assets for the purposes of operational inspections and reasonable access to
any employees or contract personnel that have been involved with the operation,
maintenance, or development of the Oil and Gas Properties and other properties
and assets and the accounting or supervision thereof.

     2.3  Environmental Assessments and Defects.

          (a) Through the Closing Date, Amerac shall have the right to enter
upon and make environmental assessments of the Oil and Gas Properties, including
the performance of soil and water tests and such other tests, examinations,
investigations, and studies as may be necessary or appropriate for the
preparation of engineering and other reports relating to the Oil

                                       11
<PAGE>
 
and Gas Properties, their condition, and the presence of Environmental
Contaminants thereon.  As of the date of this Agreement, Amerac represents that
it is not aware of any Environmental Claims except as set forth in Schedule
2.3(a).  In addition, the Selling Shareholders and Amerac agree promptly to
notify each other, as applicable, of any Environmental Claim arising after the
date of this Agreement and discovered by Amerac, Fremont, Ridgepointe, or the
Selling Shareholders, as applicable, prior to Closing.  The Selling Shareholders
and Amerac shall attempt, in good faith, to agree upon the methods of
remediating all such Environmental Claims and the estimates of the costs of such
remediations; provided, however, that except as otherwise indicated on Schedule
2.3(a), Amerac and the Selling Shareholders have agreed upon the estimate of the
Environmental Claims reflected on Schedule 2.3(a), the methods of remediating
such Environmental Claims, and the estimates of the total costs of such
remediations also set forth on Schedule 2.3(a).

          (b) If the Selling Shareholders and Amerac agree upon the existence of
an Environmental Claim, the method of remediating the same, and the estimate of
the cost of such remediation, then subject to the succeeding provisions of this
Section 2.3, Amerac shall be entitled to receive a reduction in the Initial
Purchase Consideration equal to the lesser of (i) the agreed upon estimate of
the cost of remediating such Environmental Claim, net to the interest of Fremont
in the Evaluated Interests affected by such Environmental Claim, or (ii) ten
percent (10%) of the aggregate Allocated Values of the Evaluated Interests
affected thereby; provided, however, that if the agreed upon estimate of the
cost to remediate the relevant Environmental Claim (net to the interest of
Fremont in the affected Evaluated Interest) is, in the aggregate, greater than
the aggregate Allocated Values of the Evaluated Interests affected thereby, and
the Selling Shareholders elect not to remediate such Environmental Claim as
provided hereinafter, Amerac shall be entitled to cause Fremont to convey to
FPC, prior to the Closing, the Evaluated Interests affected by such
Environmental Claim and to receive a reduction in the Initial Purchase
Consideration equal to the aggregate Allocated Values of the Evaluated Interests
thus conveyed.  Notwithstanding the provisions of the immediately preceding
sentence of this Section 2.3(b) to the contrary, however, the Selling
Shareholders shall, in all events, also have the right, but in no event shall
the Selling Shareholders be obligated, to remediate such an Environmental Claim
at their sole cost, risk, liability, and expense in accordance with applicable
Environmental Laws.  If the Selling Shareholders elect to remediate an
Environmental Claim, the Selling Shareholders shall promptly notify Amerac of
that fact.  If the Selling Shareholders complete such remediation prior to the
Closing Date, the Selling Shareholders shall have no further liability to Amerac
with respect to such Environmental Claim.  If the Selling Shareholders do not
complete the remediation of the relevant Environmental Claim on or prior to the
Closing Date, Amerac shall instruct Bank to retain in escrow, in accordance with
the provisions of the Escrow Agreement, a portion of the Deposit equal to the
lesser of (A) the agreed upon estimate of the cost (net to the interest of
Fremont in the affected Evaluated Interest) of remediating such Environmental
Claim, or (B) ten percent (10%) of the aggregate Allocated Values of the
Evaluated Interests affected thereby; and the amount thus retained in escrow
shall be deducted from the preliminary Adjusted Purchase Consideration paid at
the Closing.  The Selling Shareholders shall have sixty (60) days after the
Closing Date within which to complete the remediation of such Environmental
Claim in accordance with applicable Environmental Laws.  If the Selling
Shareholders do not complete the remediation of the relevant Environmental Claim
on or before the expiration of such sixty-day period, Amerac may elect: (i) to
offer the Selling Shareholders

                                       12
<PAGE>
 
an extension of time within which to complete such remediation; or (ii) to
receive a reduction in the final Adjusted Purchase Consideration equal to the
lesser of (A) the estimated cost (net to the interest of Fremont in the affected
Evaluated Interest) to remediate such Environmental Claim originally agreed upon
by the Selling Shareholders and Amerac, or (B) ten percent (10%) of the
aggregate Allocated Values of the Evaluated Interests affected thereby;
provided, however, that if the agreed upon estimate of the cost (net to the
interest of Fremont in the affected Evaluated Interest) to remediate the
relevant Environmental Claim is, in the aggregate, greater than the aggregate
Allocated Values of the Evaluated Interests affected thereby, Amerac shall be
entitled to cause Fremont to convey to FPC all of the right, title, and interest
of Fremont in and to the affected Evaluated Interests, and to receive a
reduction in the Initial Purchase Consideration equal to the aggregate Allocated
Values of the Evaluated Interests thus conveyed.  In the latter event, the
Selling Shareholders and Amerac shall cause Bank to distribute to Amerac all
amounts held in escrow with respect to such Environmental Claim, together with
all interest earned thereon.

          (c) If the Selling Shareholders and Amerac are unable to agree, after
meeting in good faith, on either the existence of an Environmental Claim, the
method of remediating the same, or an estimate of the cost of such remediation,
Amerac may elect to waive such asserted Environmental Claim.  If Amerac does not
waive the asserted Environmental Claim, the Selling Shareholders and Amerac
shall submit such disagreement to arbitration in accordance with the procedures
set forth in Section 2.8.  If the decision of the arbitrator is not rendered
prior to the Closing Date, Amerac shall instruct the escrow agent to retain in
escrow, in accordance with the provisions of the Escrow Agreement, a portion of
the Deposit equal to the Allocated Value of each Evaluated Interest affected by
such Environmental Claim, and the amount thus retained in escrow shall be
deducted from the preliminary Adjusted Purchase Consideration paid at the
Closing.  If such a dispute is submitted to arbitration, Amerac and the Selling
Shareholders, or either of them, shall provide to Bank written notice of such
fact that identifies the nature of the dispute and the arbitrator selected and
that instructs Bank to disburse the funds held in escrow with respect to the
relevant Environmental Claim, and all accrued interest thereon, in accordance
with instructions to be delivered to Bank by the arbitrator following the
issuance of the arbitrator's decision.  Any such notice delivered unilaterally
by Amerac or the Selling Shareholders shall also be delivered to the other
party, and proof of the delivery of such notice shall be provided to Bank.  If
the arbitrator determines that the Environmental Claim asserted by Amerac does,
in fact, exist, and that the estimate of the costs to remediate such
Environmental Claim submitted by Amerac is appropriate with respect thereto, the
arbitrator shall resolve such Environmental Claim and cause the funds held in
escrow in connection therewith to be disbursed in accordance with the provisions
of Section 2.3(b).  If the arbitrator renders a decision that is adverse, in
whole or in part, to Amerac with respect to an asserted Environmental Claim, the
funds held in escrow in connection with such asserted Environmental Claim shall
be disbursed in accordance with the decision of the arbitrator.  All amounts
distributed from the escrow account pursuant to this Section 2.3(c) will include
a pro rata share of the interest earned on such amounts.  In all events, if the
arbitrator determines that the estimated cost (net to the interest of Fremont in
the affected Evaluated Interest) to remediate an asserted Environmental Claim is
greater than the aggregate Allocated Values of the Evaluated Interests affected
thereby, Amerac shall also be entitled to cause Fremont to convey to FPC all of
the right, title, and interest of Fremont in and to the affected Evaluated
Interests, and to

                                       13
<PAGE>
 
receive a reduction in the Adjusted Purchase Consideration equal to the
aggregate Allocated Values of the Evaluated Interests thus conveyed.

     2.4  Defects and Related Adjustments.

          (a) From time to time on or before the Closing Date, but in no event
later than 5:00 p.m., Central Standard Time, on the seventh (7th) day prior to
the Closing Date, Amerac may give the Selling Shareholders written notice of any
claimed Defect ("Defect Notice").  Each such Defect Notice shall set forth (i) a
brief description of the matter constituting the claimed Defect and, if
applicable, the Evaluated Interest affected thereby, and (ii) the estimated
Defect Amount calculated in good faith by Amerac in accordance with Section
2.4(e) and attributable to the claimed Defect.  For purposes of this Agreement,
the term "Defect" means (i) any Lien, contract, agreement, obligation, or defect
of title that would cause title to a material Evaluated Interest identified with
an asterisk on Exhibit A not to be Good and Marketable Title, and (ii) any
defect or matter that would cause a breach of a representation or warranty of
the Selling Shareholders hereunder, other than the warranties contained in
Sections 3.20(a) and 3.27; provided, however, that Amerac shall not be entitled
to assert Defects pertaining to title if the relevant Defect (x) constitutes an
objection to title for which a curative requirement is inappropriate under the
standards applicable to title examiners prescribed by the State Bars of Oklahoma
or Kansas, as applicable, (y) does not relate directly to the interest of
Fremont in the relevant Evaluated Interest, or (z) otherwise relates to a matter
as to which curative requirements are routinely made by experienced oil and gas
title examiners (i.e., the acquisition of affidavits of use, possession, and
non-production) but as to which no putative or actual controversy or claim is
reflected in the public record or the books and records of Fremont or the
Selling Shareholders.

          (b) The Selling Shareholders and Amerac shall endeavor in good faith
to agree upon the existence of the Defects claimed by Amerac and the Defect
Amounts applicable thereto.  To the extent that the Selling Shareholders and
Amerac agree upon the existence of a Defect and the applicable Defect Amount,
the Selling Shareholders shall have the right, but in no event shall the Selling
Shareholders be obligated, to cure or remove to the reasonable satisfaction of
Amerac all such Defects at their sole cost, risk, and expense.  If the Selling
Shareholders elect to cure or remove a Defect, the Selling Shareholders shall
promptly notify Amerac of such fact.  If any such Defect is cured or removed to
the reasonable satisfaction of Amerac or a mutually agreeable reduction of the
Initial Purchase Consideration has been made for such Defect prior to the
Closing, the Selling Shareholders shall have no further liability to Amerac with
respect thereto.

          (c) If the Selling Shareholders and Amerac do not agree upon the
existence of a Defect and/or the Defect Amount applicable thereto prior to the
Closing, the Selling Shareholders and Amerac shall submit such disputes to
arbitration in accordance with the procedures set forth below in Section 2.8.
To facilitate the resolution of any such dispute, Amerac will instruct Bank to
retain in escrow, in accordance with the provisions of the Escrow Agreement, a
portion of the Deposit equal to the Defect Amount calculated by Amerac with
respect to the relevant Defect, and the amount thus retained in escrow shall be
deducted from the Adjusted Purchase Consideration paid at the Closing.  If such
a dispute is submitted to

                                       14
<PAGE>
 
arbitration, Amerac and the Selling Shareholders, or either of them, shall
provide to Bank written notice of such fact that identifies the nature of the
dispute and the arbitrator selected and that instructs Bank to disburse the
funds held in escrow with respect to the asserted Defect in accordance with
instructions to be delivered to Bank by the arbitrator following the issuance of
the arbitrator's decision.  Any such notice delivered unilaterally by Amerac or
the Selling Shareholders shall also be delivered to the other party, and proof
of the delivery of such notice shall be provided to Bank.  If the arbitrator
determines that the Defect asserted by Amerac does, in fact, exist, and that the
Defect Amount calculated by Amerac is appropriate with respect thereto, the
arbitrator shall resolve the asserted Defect and cause the funds held in escrow
in connection therewith to be disbursed in accordance with the provisions of
Section 2.4(d).  If the arbitrator renders a decision that is adverse, in whole
or in part, to Amerac with respect to a Defect, the disputed Defect Amount shall
be disbursed in each case in accordance with the decision of the arbitrator.
All amounts distributed from the escrow account pursuant to this Section 2.4(c)
shall include a pro rata share of the interest earned on such amounts.

          (d) If the Selling Shareholders and Amerac agree upon the existence of
a Defect and the Defect Amount applicable thereto prior to the Closing, and
either the Selling Shareholders elect not to attempt to cure or remove the
relevant Defect or the Selling Shareholders and Amerac agree that such Defect
cannot or should not be cured, Amerac shall receive a reduction in the Adjusted
Purchase Consideration paid at the Closing equal to the Defect Amount agreed
upon by the Selling Shareholders and Amerac.  If the Selling Shareholders and
Amerac agree upon the existence of a Defect and the Defect Amount applicable
thereto prior to the Closing, and the Selling Shareholders elect to attempt to
cure such Defect, but the Selling Shareholders are unable to cure such Defect
prior to the Closing, the Selling Shareholders shall provide to Amerac prompt
written notice of such fact.  At the Closing, Amerac shall instruct Bank to
retain in escrow, in accordance with the provisions of the Escrow Agreement, a
portion of the Deposit equal to the aggregate estimated Defect Amounts for all
such Defects that have not been cured or otherwise agreed upon by Amerac and the
Selling Shareholders, and such amount retained in escrow shall be deducted from
the preliminary Adjusted Purchase Consideration paid at the Closing.  The
Selling Shareholders shall have sixty (60) days after the Closing Date within
which to cure or remove to the reasonable satisfaction of Amerac all such
Defects not cured or removed to the reasonable satisfaction of Amerac prior to
the Closing.  With respect to those Defects cured or removed to the reasonable
satisfaction of Amerac or as to which the Selling Shareholders and Amerac
otherwise agree on or before the expiration of such sixty-day period, the
Selling Shareholders and Amerac shall deliver to Bank written notice instructing
Bank promptly to disburse to the Selling Shareholders the relevant Defect
Amounts, or portions thereof, attributable to the Defects so cured or removed,
and the Selling Shareholders shall have no further liability to Amerac with
respect thereto.  If, at the expiration of such sixty-day period, there remain
any Defects that have not been cured or removed to the reasonable satisfaction
of Amerac or otherwise agreed upon by the Selling Shareholders and Amerac,
Amerac may elect: (i) to offer the Selling Shareholders an extension of time
within which to complete such curative or remedial actions; or (ii) to receive a
reduction in the final Adjusted Purchase Consideration equal to the Defect
Amounts applicable to the relevant Defects.  In that event, the Selling
Shareholders and Amerac shall deliver to Bank written notice instructing Bank to
disburse to Amerac the Defect Amounts applicable to such

                                       15
<PAGE>
 
Defects.  All amounts distributed from the escrow account pursuant to this
Section 2.4(d) will include a pro rata share of the interest earned on such
amounts.

          (e) "Defect Amount" shall be determined as follows:  (i) if the Defect
affects all of Fremont's interest in an Evaluated Interest, such that the Defect
results in a complete failure of title with respect thereto, the Defect Amount
shall be the full Allocated Value for the relevant Evaluated Interest; (ii) if
the Defect is a Lien that is uncontested and liquidated in amount, then the
Defect Amount shall be an amount equal to the sum necessary to be paid to the
obligee to remove the Lien; (iii) if the Defect results from a deficiency in
Fremont's actual net revenue interest in an Evaluated Interest relative to that
shown for the affected Evaluated Interest on Exhibit A and on which the
Allocated Value of such Evaluated Interest is based, the Defect Amount will be
the difference between the Allocated Value for the affected Evaluated Interest
and an amount determined by multiplying such Allocated Value by the ratio of the
actual net revenue interest of Fremont to the Net Revenue Interest set forth for
such Evaluated Interest on Exhibit A; (iv) if the Defect results from Fremont's
actual working interest in an Evaluated Interest being greater than that shown
for the affected Evaluated Interest on Exhibit A and on which the Allocated
Value of such Evaluated Interest is based, and such larger working interest is
not accompanied by a corresponding proportionate increase in Fremont's net
revenue interest in such Evaluated Interest, the Defect Amount will be the
difference between the Allocated Value for the affected Evaluated Interest set
forth on Exhibit A and a recalculated Allocated Value for such Evaluated
Interest using the same production rates, price forecasts, and discount factors
used by Amerac to calculate the original Allocated Value, adjusted to account
for the diminution in the net present value of the future cash flows that
results from the higher working interest; and (v) if the Defect is one other
than the Defects described above in clauses (i), (ii), (iii), and (iv) of this
Section 2.4(e), the Defect Amount shall be an amount determined in good faith by
the mutual agreement of Amerac and the Selling Shareholders, taking into
account, as applicable, the Allocated Value of the relevant Evaluated Interest,
the legal effect of the Defect, and the potential economic effect of the Defect
over the life of the relevant Evaluated Interest or otherwise with respect to
the transactions contemplated herein.  In no event shall the Defect Amount
established under this Agreement for a Defect pertaining to an Evaluated
Interest exceed the Allocated Value for such Evaluated Interest.

     2.5  Preferential Purchase Rights and Consents to Assign.

          (a) With respect to each preferential purchase right pertaining to an
Evaluated Interest that is triggered by the transactions contemplated in this
Agreement, the Selling Shareholders shall cause Fremont, prior to the Closing,
to send to the holder of each such right a notice offering to sell to such
holder, in accordance with the contractual provisions applicable to such right,
the Evaluated Interest covered by such right on substantially the same terms as
are set forth herein and for the Allocated Value of such Evaluated Interest set
forth on Exhibit A, subject to adjustments and all other terms and provisions of
this Agreement.  In addition, prior to the Closing, the Selling Shareholders
shall cause Fremont to send to each holder of a right to consent to assignment
pertaining to an Evaluated Interest which is triggered by the transactions
contemplated in this Agreement a notice seeking such party's consent to such
transactions.  Simultaneously therewith, the Selling Shareholders shall cause
Fremont to deliver a copy of such notices to Amerac.

                                       16
<PAGE>
 
          (b) If, prior to the Closing, any holder of such a preferential
purchase right notifies Fremont or the Selling Shareholders that it intends to
consummate the purchase of the Evaluated Interest to which its preferential
purchase right applies, the exercise of such preferential purchase right shall
constitute a Defect, and the Initial Purchase Consideration shall be reduced by
the Allocated Value of the relevant Evaluated Interest.  The Selling
Shareholders shall be entitled to all proceeds paid by a party exercising such a
preferential purchase right prior to the Closing.  If the holder of such a
preferential purchase right fails to consummate the purchase of the Evaluated
Interest affected by such right on or prior to the Closing Date, then the
Selling Shareholders shall so notify Amerac and, subject to Amerac's
satisfaction that such preferential right has been waived, the Defect resulting
from the proposed exercise of such preferential right shall be deemed to have
been cured.  If a preferential purchase right burdening an Evaluated Interest is
exercised after the Closing Date, such exercise shall not constitute a Defect,
and Amerac shall be entitled to all proceeds paid for the affected Evaluated
Interest by the party exercising the preferential purchase right.

          (c) There shall be no reduction in the Initial Purchase Consideration
with respect to Evaluated Interests for which preferential purchase rights have
been waived, or as to which the period to exercise such right has expired prior
to the Closing.

          (d) With respect to any portion of an Evaluated Interest as to which a
required consent has not been obtained prior to the Closing, such failure shall
constitute a Defect affecting the relevant Evaluated Interest, and the Selling
Shareholders and Amerac shall have the rights and remedies provided herein with
respect thereto.

     2.6  Interest Additions.  The Selling Shareholders shall be entitled to an
increase in the Initial Purchase Consideration with respect to any additional
interest in or with respect to any material Evaluated Interest identified with
an asterisk on Exhibit A that is reflected of record and as to which Fremont has
Good and Marketable Title, the net effect of which is either (a) to increase
permanently Fremont's net revenue interest in the affected Evaluated Interest
above that shown for such Evaluated Interest on Exhibit A, or (b) to decrease
Fremont's working interest for the relevant Evaluated Interest below that shown
for such Evaluated Interest on Exhibit A without a corresponding decrease in the
"Net Revenue Interest" shown for such Evaluated Interest on Exhibit A; provided,
however, that the Selling Shareholders shall not be entitled to such an increase
in the Initial Purchase Consideration in the case of additional interests
resulting from Fremont's failure to execute and deliver to FEI or other
affiliates of the Selling Shareholders recorded assignments of overriding
royalty interests in production from one (1) or more of such material Evaluated
Interests owed to such parties under existing intercompany arrangements between
Fremont and such parties.  To be entitled to such an adjustment in the Initial
Purchase Consideration, the Selling Shareholders shall furnish to Amerac written
notice of any such additional interests no later than 5:00 p.m., Central
Standard Time, on the seventh (7th) day prior to the Closing Date.  Such notice
shall set forth the increase in interest asserted by the Selling Shareholders
and the Evaluated Interest affected thereby.  If Amerac is able to verify to its
reasonable satisfaction the existence of any such additional interest based upon
record title examinations or other title-related due diligence conducted by
Amerac in connection with this Agreement, the Initial Purchase Consideration
shall be adjusted by increasing the Initial Cash Amount by an amount equal to
the value of such additional interest.  Such value shall be

                                       17
<PAGE>
 
determined consistently with the manner in which reductions to the Initial
Purchase Consideration are determined under Section 2.4.  If the Selling
Shareholders and Amerac are unable to agree on the existence or value of such an
additional interest, the Selling Shareholders and Amerac shall submit such
dispute to arbitration in accordance with the procedures set forth in Section
2.8.  Upon the arbitrator's determination of the existence of the asserted
additional interest and its value, the value of such additional interest as
determined by the arbitrator shall be credited to the Selling Shareholders and
taken into account in the calculation of the final Adjusted Purchase
consideration reflected in the Final Settlement Statement.

     2.7  Casualty Loss.  The Selling Shareholders shall give Amerac prompt
written notice of any fire, explosion, accident, blowout, earthquake, act of the
public enemy, act of God, or other similar casualty event ("Casualty") that
occurs with respect to any Evaluated Interest prior to the Closing Date,
together with a description of the applicable insurance coverage and the extent
of Fremont's exposure as the result of such Casualty.  For purposes of this
Agreement, any such Casualty shall be treated in the same manner as an
Environmental Claim, with the result that the rights and obligations of the
Selling Shareholders and Amerac shall be governed by the provisions of Section
2.3(b) and Section 2.3(c).

     2.8  Arbitration.

          (a) Any disagreement, difference, or dispute among the parties that is
provided in this Agreement to be resolved pursuant to arbitration shall be
resolved according to the procedures set forth in this Section 2.8.  ALL OTHER
DISAGREEMENTS, DIFFERENCES, OR DISPUTES ARISING BETWEEN THE SELLING SHAREHOLDERS
AND AMERAC UNDER THE TERMS OF THIS AGREEMENT SHALL NOT BE SUBJECT TO ARBITRATION
AND SHALL BE DETERMINED BY A COURT OF COMPETENT JURISDICTION, UNLESS THE SELLING
SHAREHOLDERS AND AMERAC OTHERWISE MUTUALLY AGREE.  For purposes of this
Agreement, the term "court of competent jurisdiction" shall not include justice
of the peace courts in the State of Texas.  If the parties determine that
arbitration is necessary under any provision hereof that calls for the
arbitration of disputes, then no later than five (5) days after the Selling
Shareholders and Amerac have confirmed to each other in writing their intentions
to arbitrate the relevant dispute, the Selling Shareholders shall select an
arbitrator, and Amerac shall select an arbitrator.  Promptly following their
selection, the arbitrators selected by, respectively, the Selling Shareholders
and Amerac jointly shall select a third arbitrator, who shall hear and decide
all matters relating to the dispute that is subject to arbitration under this
Agreement.  All arbitrators selected under this Agreement shall be experts with
respect to oil and gas, environmental, operations, land, legal, or accounting
issues, as applicable, and in each case shall have at least ten (10) years
experience in the oil and gas industry.  If any arbitrator selected under this
Section 2.8 (a) should die, resign, or otherwise be unable to perform his duties
hereunder, a successor arbitrator shall be selected pursuant to the procedures
set forth in this Section 2.8(a).

          (b) The arbitrator shall settle all disputes in accordance with the
Federal Arbitration Act and the Rules of the American Arbitration Association,
to the extent that such Rules do not conflict with the terms of such Act or the
provisions of this Agreement.  The decision of the arbitrator shall be binding
on the parties and, if necessary, may be enforced in

                                       18
<PAGE>
 
any court of competent jurisdiction.  The law governing all such disputes shall
be the laws of the State of Texas without regard to conflicts of laws
principles; provided, however, that with respect to disputes relating to Defects
as to title or Environmental Claims relating to alleged violations of local
Environmental Laws, the law governing such dispute shall be the laws of the
state in which the affected Evaluated Interest is located, without regard to
conflicts of laws principles.  The charges and expenses of the arbitrator shall
be shared equally by the Selling Shareholders and Amerac.

          (c) Any arbitration hearing shall be held in Houston, Harris County,
Texas.  The arbitration hearing shall commence as soon as is practical, but in
no event more than thirty (30) days, after the selection of the arbitrator.  At
such a hearing, the Selling Shareholders and Amerac shall each have up to five
(5) days within which to present their respective positions on the issues being
arbitrated.  In fulfilling his duties, the arbitrator shall be bound by the
terms and provisions of this Agreement, but may also consider such other matters
as, in the opinion of the arbitrator, are necessary or helpful to make a proper
determination.  In addition, the arbitrator may consult with and engage, with
the approval and at the joint expense of the Selling Shareholders and Amerac,
disinterested third parties (including, without limitation, petroleum engineers
and consultants) to advise the arbitrator.  The arbitrator shall issue his final
determination of all issues no later than ten (10) days after the conclusion of
the arbitration hearing.  If the matter in dispute relates to whether one (1) or
more of the conditions to the obligation of either the Selling Shareholders or
Amerac, as applicable, to close the transactions contemplated herein has been
satisfied, the relevant condition shall be suspended, and the party entitled to
enforce such condition shall not be entitled to terminate this Agreement
pursuant to Section 10.1 solely because such condition remains unsatisfied.  In
that event, the Closing Date shall be extended to the next Business Day
following the issuance by the arbitrator of his final determination, at which
time the suspension of such condition shall cease, and the Closing shall take
place unless this Agreement is terminated at that time by either party having a
right to do so pursuant to Article X.

thereof.  All of the wells included in the Evaluated Interests have been
drilled, completed, and operated within the boundaries of the Leases or within
the limits otherwise permitted by contract, pooling or unit agreement, and by
law and in compliance with the provisions of the relevant Applicable Contracts
and all applicable rules, regulations, permits, judgments, orders and decrees of

are the only wells located on the Oil and Gas Properties.

     3.23 Marketing.  Except as disclosed on Schedule 3.23, no amounts of
hydrocarbons produced from the Evaluated Interests are subject to a sales
contract (except for contracts terminable without penalty on not more than
thirty (30) days notice), and except as may be contained in any document
described on Schedule 3.23, no person has any call upon, option to purchase, or
similar rights under any agreement with respect to the Evaluated Interests or to
the production therefrom.  Fremont has not in any respect collected, nor will

of oil, condensate, and gas from the Evaluated Interests were being received in
all respects by Fremont in a timely manner and were not being held in suspense
for any reason, except as disclosed on Schedule 3.23.  Fremont has not been, nor
will be, obligated by virtue of any prepayment made under any production sales
contract or any other contract containing a "take-or-pay" clause, or under any

arrangement to deliver oil, gas, or other minerals produced from or allocated to
any of the Evaluated Interests at some future time without receiving full
payment therefor at the time of delivery, except as disclosed on Schedule 3.23.
Except as disclosed on Schedule 3.23, there are no material gas imbalances as
between Fremont and any third party with respect to the Evaluated Interests.

     3.24 Applicable Contracts.  With respect to the Applicable Contracts:  (a)
to the best knowledge of each Selling Shareholder after due inquiry, all
Applicable Contracts are in full force and effect and are the valid and legally
binding obligations of the parties thereto and are enforceable in accordance
with their respective terms, except to the extent that such enforcement may be
limited by applicable bankruptcy, insolvency and similar laws affecting
creditors' rights generally, and by general equitable principles (regardless of
whether such enforceability is considered in a proceeding in equity or at law);
(b) to the best knowledge of each Selling Shareholder after due inquiry, Fremont
is not in material breach or material default, nor has there occurred any event,
fact, or circumstance that, with the lapse of time or giving of notice, or both,
would constitute such a breach or default by Fremont, with respect to any of its
obligations under any Applicable Contract; and (c) neither Fremont nor, to the
best knowledge of each Selling Shareholder after due inquiry, any other party to
any Applicable Contract has given or threatened to give notice of any action to
terminate, cancel, rescind, or procure a judicial reformation of any Applicable
Contract or any provision thereof.

fulfilled all requirements for filings, certificates, disclosures of parties in
interest, and other similar matters contained in (or otherwise applicable

is fully qualified to own, hold, and exercise such rights under such Leases or
other documents; and (b) there are no express contractual obligations to drill
additional wells or to engage in other express development operations, except

or in part, for the costs of cleaning up, remediating, removing, or responding
to a Release or a threat of a Release of Environmental Contaminants; or (iv) the

     3.28 Plugging and Abandonment.  No well included in the Evaluated
Interests, as of the Engineering Date, had been permanently plugged and
abandoned or AFE'd for permanent plugging and abandonment.

     3.29 Disbursement of Proceeds.  Except proceeds from the sale of production
attributable to the Oil and Gas Properties being held in suspense in accordance
with prudent industry practice, all of such proceeds of production have been and
are being accounted for under appropriate division orders, transfer orders, or
similar documents signed by or otherwise binding on the parties receiving such
proceeds and reflecting as to each party the decimal interest of such party.

     3.30 Certain Agreements; Payouts.  Except as set forth in Schedule 3.30, no
Evaluated Interest is subject to any area of mutual interest agreement or any
farmout or farmin agreement pursuant to which Fremont or Amerac may be obligated
to make assignments after the Engineering Date.  Except as set forth on Schedule
3.30, no Evaluated Interest is subject to any tax partnership.  Where Exhibit A
shows an Evaluated Interest described therein to be subject to change "After
Reversion," or similar designations, such change will occur upon either the
recovery from the production from such Evaluated Interest of a volume of such
production, or the recovery from the proceeds of production from such Evaluated
Interest of a sum of money, in either case as set forth in Schedule 3.30 as the
"Reversion Amount".

     3.31 Information.  To the best knowledge of each Selling Shareholder after
due inquiry, all of the revenue and cost information, records, and data relating
to the Evaluated Interests furnished by the Selling Shareholders to Amerac,
either prior to the execution of this Agreement or to be furnished prior to
Closing, is not, and shall not be, incorrect or inaccurate in any material
respect when so furnished, and no documents relating thereto were removed, nor
were any information or documents relating thereto omitted, from the data or
documents relating thereto furnished by the Selling Shareholders to Amerac,
which are necessary to make the data furnished not misleading in any material
respect; provided, however, that this representation and warranty is limited
solely to matters of fact that are not otherwise publicly available or known to
Amerac.

obligation of Amerac or to a loss of any benefit to which Amerac is entitled
under any provision of (a) the certificate of incorporation or bylaws of Amerac,

applicable requirements of the 1934 Act and 1933 Act and the rules and
regulations promulgated thereunder, and did not contain any untrue statement of

                               GENERAL COVENANTS
                               -----------------

     Amerac, Ridgepointe, Fremont, and the Selling Shareholders agree that:

     5.1  Access to Information.  Each party (a) shall afford to the other
parties and their respective counsel, financial advisors, and auditors and any
person providing or proposing to provide financing for the transactions
contemplated hereby and their respective authorized representatives and agents
reasonable access to all of its respective offices, properties, books and
records, (b) will furnish to such persons such financial and operating data and
other information as such persons may reasonably request, and (c) will instruct
its respective employees, counsel, and financial advisors to cooperate with such
persons in their investigation of the business of such party, provided that the
confidentiality of any data or information so acquired shall be maintained in
accordance with Section 5.5 of this Agreement.

     5.2  Reasonable Best Efforts.  Subject to the terms and conditions of this
Agreement, each party will use its reasonable best efforts to take, or to cause
to be taken, all action and to

                                       31
<PAGE>
 
do, or cause to be done, all things necessary, proper, or advisable under
applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement, including (a) cooperation in
determining whether any action by or in respect of, or filing with, any
governmental body, agency, or official or authority is required, or any actions,
consents, approvals, or waivers are required to be obtained from parties to any
material contracts, in connection with the consummation of the transactions
contemplated by this Agreement; (b) cooperation in seeking and obtaining any
such actions, consents, approvals or waivers; and (c) the execution of any
additional instruments necessary to consummate the transactions contemplated
hereby.

     5.3  Public Announcements.  The parties agree to consult with each other
before issuing any press release or making any public statement with respect to
this Agreement and the transactions contemplated hereby and, except as may be
required by applicable law, the parties hereto will not issue any such press
release or make any such public statement prior to such consultation.  Amerac
will give all notices required under the 1933 Act, 1934 Act, and any other
applicable state or federal securities laws.

     5.4  Notification of Certain Matters.  Each party shall give prompt notice
to the others of (a) the occurrence or nonoccurrence of any event the occurrence
or nonoccurrence of which would be likely to cause any representation or
warranty of such party contained in this Agreement to be untrue or inaccurate in
any material respect at or prior to the Closing Date and (b) any material
failure of such party to comply with or satisfy any, covenant, condition, or
agreement to be complied with or satisfied by it hereunder; provided, however,
that the delivery of any notice pursuant to this Section 5.4 shall not limit or
otherwise affect the remedies available hereunder to the parties receiving such
notice.

     5.5  Confidential Information.  Each party and its affiliates will hold,
and will use their best efforts to cause their respective accountants, counsel,
consultants, advisors, and agents to hold, in confidence all confidential
documents and information concerning the other parties and their respective
affiliates furnished to such party or its affiliates in connection with the
transactions contemplated in this Agreement, except to the extent that such
information can be shown to have been (a) previously known on a nonconfidential
basis by such party, (b) in the public domain through no fault of such party,
(c) later lawfully acquired by such party from sources other than the other
parties or their affiliates, (d) disclosed pursuant to the operation of
applicable law, regulation, or other governmental authority, or (e) disclosed
under compulsion of oral questions at trial, interrogatories, requests for
information or documents, subpoena, civil investigation demand, or similar
judicial or administrative process; provided that such party may disclose such
information to its officers, directors, employees, accountants, counsel,
consultants, advisors, and agents in connection with the transactions
contemplated by this Agreement and to its lenders in connection with obtaining
the financing for and consents to the transactions contemplated by this
Agreement so long as such persons are informed by such party of the confidential
nature of such information and are directed by such party to treat such
information confidentially.  The obligation of such party and its affiliates to
hold any such information in confidence shall be satisfied if they exercise the
same care with respect to such information as they would take to preserve the
confidentiality of their own similar information.  If this Agreement is
terminated, each party and its affiliates will, and will use their best efforts
to cause

                                       32
<PAGE>
 
their respective accountants, counsel, consultants, advisors, and agents to,
destroy or deliver to any other party, upon request, all documents and other
materials, and all copies thereof, obtained by such party or its affiliates or
on their behalf from the other party and its affiliates in connection with this
Agreement that are subject to such confidence.  This Section 5.5 supersedes any
prior confidentiality agreement among the parties.

     5.6  Certain Tax Matters.

          (a) Amerac shall cause to be prepared and filed any tax returns,
statements or reports ("Tax Returns") of Ridgepointe and Fremont covering
taxable periods ending on or before the Closing Date which were not required to
have been filed on or before the Closing Date; provided that Amerac must obtain
the consent of the Selling Shareholders to the form and content of any such Tax
Returns, prior to the filing thereof, which consent shall not be unreasonably
withheld.  Such returns shall be prepared by Petroleum Financial, Inc. ("PFI"),
and the costs associated with the preparation of such returns shall be borne 5/6
by the Selling Shareholders and 1/6 by Amerac; provided, however, that in no
event shall the Selling Shareholders be obligated to bear any portion of any
such preparation costs in excess of $2,000.00.  The Selling Shareholders shall,
jointly and severally, within fifteen (15) days after payment thereof and
receipt of notice of such payment, reimburse Amerac and its affiliates for all
taxes (including interest, penalties and additions to tax) ("Taxes") relating to
taxable periods of Fremont and Ridgepointe ending on or before the Closing Date.

          (b) Amerac shall prepare and file, or cause to be prepared and filed,
any Tax Returns of Fremont and Ridgepointe covering taxable periods which begin
before the Closing Date and end after the Closing Date ("Straddle Periods"). The
Selling Shareholders shall, jointly and severally, within fifteen (15) days
after payment thereof and notice of such payment, reimburse Amerac for all Taxes
for any Straddle Period, to the extent related to the portion of the Straddle
Period ending on the Closing Date.  For such purposes, the portion of any Tax
attributable to the portions of a Straddle Period ending on the Closing Date and
beginning after the Closing Date shall be determined by apportioning the Tax for
the entire Straddle Period among such periods based on the number of days in
each such period; provided that, in the case of Taxes based upon or related to
income or receipts, such portion shall be the amount of Tax which would have
been due if the relevant Straddle Period ended on the Closing Date.  Any credits
relating to a Straddle Period shall be taken into account as though the relevant
Straddle Period ended on the Closing Date.  All determinations necessary to give
effect to the foregoing allocations shall be made in a manner consistent with
prior practices of Fremont or Ridgepointe, as the case may be.

          (c) The Selling Shareholders shall reasonably cooperate with Amerac in
connection with the filing of Tax Returns pursuant to this Section t.6 and any
audit, litigation, or other proceeding with respect to Taxes.  Such cooperation
shall include the provision of copies, at the requesting party's expense, of
records and information relevant to any such Tax Return or proceeding and making
employees available on a mutually convenient basis to provide additional
information and explanation of any material provided hereunder.  The Selling
Shareholders shall cause Fremont and Ridgepointe duly, accurately, and timely
(with regard to

                                       33
<PAGE>
 
any extensions of time) to file all Tax Returns and other documents required to
be filed by them, and to pay all taxes required to be paid by them, on or before
the Closing Date.

     6.3  Other Offers.  From the date hereof until the termination of this

knowingly encourage any Acquisition Proposal (as hereinafter defined), or (b)
except to the extent that the Board of Directors of Fremont or Ridgepointe, as
applicable, determines, upon advice of outside counsel, that it is otherwise
required by its fiduciary duties to do so, engage in negotiations with, or
disclose any nonpublic information relating to Fremont or Ridgepointe, or afford
access to the properties, books, or records of Fremont or Ridgepointe, in each
case to any person that is considering making or has made an Acquisition
Proposal; provided that nothing contained in this Section 6.3 shall prohibit
Fremont or Ridgepointe or their respective Board of Directors from making such
disclosures to Fremont's or Ridgepointe's shareholders which, in the judgment of
the Board of Directors of Fremont or Ridgepointe, on the advice of outside
counsel, is required under applicable law.  Fremont and Ridgepointe or the
Selling Shareholders shall promptly notify Amerac after receipt of any
Acquisition Proposal or any request for nonpublic information relating to

Fremont or Ridgepointe, or the acquisition of any equity interest in, or a
substantial portion of the assets of, Fremont or Ridgepointe, other than the
transactions contemplated by this Agreement.

     6.4  Imbalances.  The Selling Shareholders understand that Amerac has not
included in its engineering pertaining to the Evaluated Interests the effect of
any imbalances with respect to production taken or marketed from or attributable
to the Oil and Gas Properties.  If either the Selling Shareholders or Amerac
determines, on or prior to the expiration of forty-five (45) days after the
Closing Date, that imbalances exist that have not previously been disclosed with
respect to the Oil and Gas Properties, then, subject to verification by the
other party, the Adjusted Purchase Consideration shall be adjusted (a) upward by
an amount equal to (i) the current market value of any hydrocarbons that
Fremont, as an underproduced party, may be entitled to take in excess of its

for which is set forth in Section 2.4, and the warranty contained in Section
3.27, to the extent of Environmental Claims pertaining to Evaluated Interests
other than those referred to above in clause (b) of this Section 8.1 as to which
Amerac receives a reduction in the Adjusted Purchase Consideration pursuant to
Section 2.3) or an inaccurate or erroneous material representation made by any
Selling Shareholder in this Agreement.

     8.2  Indemnities of Amerac.  Notwithstanding the Closing, and regardless of
any investigation made at any time by or on behalf of the Selling Shareholders
or any information the Selling Shareholders may have, Amerac shall indemnify and
hold harmless the Selling Shareholders and their affiliates, partners, officers,
directors, shareholders, employees, agents, and representatives from and against

way to, and to pay the Selling Shareholders any sum that the Selling
Shareholders pay or become obligated to pay on account of: (a) injury to or
death of any person, persons, or other living things, or loss or destruction of

any breach or default in the performance by Amerac of any material covenant or
material agreement of Amerac contained in this Agreement; or (e) any breach of a
material warranty or an inaccurate or erroneous material representation made by
Amerac in this Agreement.

     8.3  Notice of Claims; Defense; Settlement.  Except as provided
hereinafter, no Claim may be indemnified under this Agreement unless the party
requesting indemnification gives notice to the party from whom indemnification
is sought of the Claim for which indemnification is sought on or before the
expiration of two (2) years after the Closing Date; provided, however, that with
respect to claims for indemnification under Sections 8.1(b), 8.1(d), 8.1(e),
8.2(c), and 8.2(d), the party seeking indemnification must give notice to the
party from whom indemnification is sought of the Claim for which indemnification
is sought on or before the expiration of ten (10) days after the expiration  of
the statute of limitations applicable to such Claim.  Upon the discovery by any
party entitled to indemnification under any provision of this Agreement of facts
giving rise to a Claim for indemnification hereunder, including the receipt by
any such party of notice of any Claim by any third party, the party entitled to
indemnification shall give prompt written notice of any such Claim to the
Selling Shareholders or Amerac, as appropriate, depending upon which of such
parties is obligated to provide the requested indemnification.  For purposes of
this Section 8.3, the party giving notice of a Claim and requesting
indemnification shall be referred to as the "indemnified party," and the party
receiving notice of a Claim and from which indemnification is sought shall be
referred to as the "indemnifying party."  Each such notice shall set forth the
facts known to the indemnified party pertaining to the claim and shall specify
the manner in which the indemnified party proposes to respond to the claim.
Within ten (10) days of the receipt by the indemnifying party of such notice,
the indemnifying party shall state in writing to the indemnified party:  (a)
whether the indemnified party may proceed to respond to the Claim in the manner
set forth in its notice, or (b) whether the indemnifying party shall assume
responsibility for and conduct the negotiation,

                                       40
<PAGE>
 
defense, or settlement of the Claim, and if so, the specific manner in which the
indemnifying party proposes to proceed (which assumption of responsibility
shall, in no event, be an admission or recognition of the legitimacy of
truthfulness of such Claim).  If the indemnifying party assumes control of the
Claim, the indemnified party shall at all times have the right to participate in
the defense thereof and to be represented, at its sole expense, by counsel
selected by it.  If the indemnifying party disputes its potential liability to
the indemnified party within such ten-day period, the indemnified party shall be
entitled to assume responsibility for and conduct the negotiation, defense, or
settlement of the Claim.  In addition, if the indemnifying party disputes its
potential liability to the indemnified party with respect to such a Claim, and
the parties are unable to resolve their differences, the parties agree to submit
their disagreement to arbitration in accordance with the provisions of Section
2.8.  No Claim shall be compromised or settled by either the indemnifying party
or the indemnified party, as applicable, in any manner that might adversely
affect the interest of the other party without the prior written consent of such
other party.  As a condition precedent to indemnification under this Agreement,
the indemnified party shall assign to the indemnifying party, and the
indemnifying party shall become subrogated to, all rights, claims, and causes of
action of the indemnified party against third persons arising out of or
pertaining to the matters for which the indemnifying party shall provide
indemnification.  The amount of the indemnified party's claim for
indemnification shall be reduced by the amount of any insurance reimbursement
paid to the indemnified party pertaining to the claim.

given to the party against whom enforcement is sought on or before the
expiration of ten (10) days after the expiration of the applicable statute of
limitations pertaining to the relevant breach or default.  Notwithstanding the
provisions of this Section 11.2 to the contrary, all matters relating to the
assertion of rights to indemnification under this Agreement shall be governed by

                    AMENDMENT NO. 1 TO ACQUISITION AGREEMENT
                    ----------------------------------------


          This AMENDMENT NO. 1 TO ACQUISITION AGREEMENT ("Amendment No. 1") is
executed as of January 15, 1996, effective as of January 5, 1996, by AMERAC
ENERGY CORPORATION, a Delaware corporation ("Amerac"), POWELL RESOURCES, INC.,
an Oklahoma corporation ("Powell"), THE LANGSTROTH FAMILY LIMITED I, a Florida
limited partnership (the "Partnership"), THOMAS O. GOLDSWORTHY, and JAMES B.
TOLLERTON (collectively, the "Selling Shareholders"), RIDGEPOINTE RESOURCES,
INC. ("Ridgepointe"), FREMONT ENERGY CORPORATION ("Fremont"), and FREMONT
PETROLEUM CORPORATION ("FPC").

                                   RECITALS:
                                   ---------


          WHEREAS, pursuant to the Acquisition Agreement dated as of January 5,
1996, between Amerac, the Selling Shareholders, Ridgepointe, Fremont, and FPC
(the "Acquisition Agreement"), the Selling Shareholders agreed to sell to
Amerac, and Amerac agreed to purchase from the Selling Shareholders, all of the
shares of "Fremont Common Stock" not owned by Ridgepointe and all of the shares
of "Ridgepointe Common Stock" (as both of such terms are defined in the
Acquisition Agreement) owned by the Selling Shareholders for the consideration
and on the terms set forth therein (capitalized terms defined in the Acquisition
Agreement having the same meanings when used in this Amendment No. 1 unless
expressly stated otherwise); and

          WHEREAS, the parties hereto desire to amend the Acquisition Agreement
in certain respects;

          NOW, THEREFORE, for the consideration recited in the Acquisition
Agreement and other good and valuable consideration, the receipt and sufficiency
of which are hereby acknowledged, Amerac, the Selling Shareholders, Ridgepointe,
Fremont, and FPC hereby agree that:

          1.   Section 1.4 of the Acquisition Agreement is amended by deleting
therefrom the last sentence thereof and by substituting therefor the following
provision:

          At the Closing, the Selling Shareholders shall provide to Amerac
          documentation reflecting the full payment and/or cancellation of all
          such intercompany accounts and the consummation of all such
          transactions.

          2.   The reference to "Section t.6" contained in Section 5.6(c) of the
Acquisition Agreement is corrected to read "Section 5.6".

          3.   Section 7.2 of the Acquisition Agreement is deleted in its
entirety, and the following provision is substituted therefor:

                                       51
<PAGE>
 
          7.2  Federal and State Income Tax Refunds.  If Fremont receives a
     refund in connection with its federal or state income tax returns for the
     fiscal years ended March 31, 1993, 1994, 1995, or 1996, Amerac agrees to
     pay the cash equivalent of any such refund, promptly after receipt, to the
     Selling Shareholders as an additional upward adjustment to the Initial
     Purchase Consideration.

          4.   Section 9.1(b) of the Acquisition Agreement is deleted in its
entirety.  No renumbering or relettering with respect to any of the provisions
of Section 9.1 of the Acquisition Agreement shall result from the deletion of
this provision.

          5.   The signature blocks appearing on page 48 of the Acquisition
Agreement are amended as follows:

               (a) the signature block for The Langstroth Family Limited I is
     moved from its current position following the signature block for Thomas O.
     Goldsworthy to the position immediately following the signature block for
     Powell Resources, Inc., and preceding the caption "Other Selling
     Shareholders"; and

               (b) the phrase "Other Parties" is inserted between the signature
     block for James B. Tollerton and the signature block for Fremont Energy
     Corporation.

The purpose of the amendments contained in this Paragraph 5 is to clarify that,
for purposes of the Acquisition Agreement, the term "Other Selling Shareholders"
refers to Thomas O. Goldsworthy and James B. Tollerton only.

          6.   Amerac, the Selling Shareholders, Ridgepointe, Fremont, and FPC
do hereby adopt, ratify, and confirm the Acquisition Agreement as amended hereby
and declare the Acquisition Agreement, as so amended, to be in full force and
effect.

          IN WITNESS WHEREOF, Amerac, the Selling Shareholders, Ridgepointe,
Fremont, and FPC have executed this Amendment No. 1 as of the date first above
written.

<PAGE>
 
successor rule or provision then in force) under the Act, or (iii) it may be

2.   Shelf Registration.

          (a) At any time after the date one year after the date of this
Agreement and before the date three years after the date of this Agreement, one
or more of Holders of Registrable Securities holding an aggregate of a majority
of the Registrable Securities may request in writing that the Issuer file a
"shelf" registration statement on an appropriate form pursuant to Rule 415 (or
any successor provision that may be adopted by the Commission) under the Act
covering the registration of all, or any portion in excess of 50%, of the
Registrable Securities (the "Shelf Registration").  Such Holder or Holders shall
provide with such request an opinion of counsel that the amount of Registrable
Securities to be offered for public sale in the aggregate may not be sold within
a period of 90 days of the date of such request in accordance with the
provisions of Rule 144 promulgated under the Act.  Within five business days of
receipt of such request, the Issuer shall give notice of such request to all of
the remaining Holders of Registrable Securities of its receipt of such request
from such Holder or Holders.  Upon the written request of any such Holder
delivered to the Issuer within 10 days after receipt from the Issuer of such
notification (the "Determination Date"), the Issuer will use its best efforts to
cause such of the Registrable Securities as may be requested by any such Holder
(including the Holder or Holders of Registrable Securities giving the initial
request to register hereunder) to be registered under the Act in accordance with
the terms of this Section 2.

          (b) Issuer agrees to use its best efforts to file with the Commission
within 30 days of the Determination Date the Shelf Registration, have the Shelf
Registration declared effective as soon as practicable after the filing thereof
and to keep the Shelf Registration continuously effective until three years
after the date of this Agreement or until there are no more Registrable
Securities, whichever shall occur first.  Issuer further agrees to supplement or
amend the Shelf Registration, (i) if required by the Act or (ii) to update
information with respect to the Holders or the plan of distribution if requested
by the Holders of a majority of the Registrable Securities, and Issuer agrees to
furnish to the Holders copies of any such supplement or amendment promptly after
its being filed with the Commission.  The Holders of Registrable Securities
registered in the Shelf Registration shall pay one-half of the Registration
Expenses (as hereinafter defined) in connection with the Shelf Registration,
whether or not it becomes effective.  Issuer will make available to its
securityholders (i) as soon as reasonably practicable, from time to time, for
three years, statements of operations covering each successive three-month
period, commencing on the first day of the fiscal quarter next succeeding the
effective date of such Shelf Registration and (ii) as soon as reasonably
practicable after 12 months have elapsed from such date, a statement of
operations covering a period of 12 months, which earnings statements shall
satisfy the provisions of Section 11(a) of the Act.

          (c) The Holders of a majority of the Registrable Securities, in their
sole discretion, shall determine whether to proceed with, withdraw from or
terminate the Shelf Registration.  If the Shelf Registration is withdrawn or
terminated pursuant to the foregoing clause and the Holders pay all Registration
Expenses incurred by Issuer in connection with the

                                       2
<PAGE>
 
terminated or withdrawn registration statement, such registration statement
shall not constitute the Shelf Registration pursuant to this Section 2.

          (d) In the event Issuer grants piggy-back registration rights to other
securityholders and such securityholders elect to have shares of Amerac Common
Stock registered in the Shelf Registration, the amount of Registration Expenses
payable by the Holders pursuant to paragraph 2(b) shall be reduced to an amount
equal to the product of (i) one-half of the Registration Expenses and (ii) the
percentage of the total number shares of Amerac Common Stock being registered in
the Shelf Registration represented by the Registrable Securities being
registered on behalf of the Holders.

3.   Piggy-Back Registration

          (a) If at any time beginning on the date hereof and ending three years
after such date the Issuer proposes to file a registration statement under the
Act with respect to any offering of any securities of Issuer (other than a
registration statement on Form S-4 or S-8 (or any substitute form for comparable
purposes that may be adopted by the Commission) or a registration statement
filed in connection with an exchange offer or an offering of securities solely
to Issuer's existing securityholders), then Issuer shall in each such case give
written notice of such proposed filing to the Holders of Registrable Securities
as soon as practicable (but in no event less than 10 days before the anticipated
filing date), and such notice shall offer such Holders the opportunity to
register such number of shares of Registrable Securities for sale pursuant to
such offering as each such Holder may request.

          (b) Issuer shall use its best efforts to cause the managing
underwriter or underwriters of a proposed underwritten offering to permit the
Registrable Securities requested to be included in the registration statement
for such offering to be included on the same terms and conditions as any similar
securities of Issuer or of any other selling securityholders included therein.
Notwithstanding the foregoing, if the managing underwriter or underwriters of
such offering determines that because of the size of the offering which the
Holders of such Registrable Securities, the Issuer, and such other persons
intend to make, the success of the offering of the Issuer's securities could
reasonably be expected to be materially and adversely affected by inclusion of
the Registrable Securities requested to be included, then the managing
underwriters shall provide written notice of such determination to the Holders
of the Registrable Securities, and the amount of securities to be offered for
the accounts of Holders shall be reduced pro rata among the Holders to the
extent necessary to reduce the total amount of securities to be included in such
offering to the amount recommended by such managing underwriter or underwriters;
provided that if securities are being offered for the account of other persons
or entities other than Issuer, then the proportion by which the amount of
securities intended to be offered by Holders is reduced shall not exceed the
proportion by which the amount of securities intended to be offered by such
other persons or entities other than Issuer is reduced.  Issuer will bear all
Registration Expenses in connection with a piggy-back registration.

          (c) As a condition to a Holder's participation in any underwriting
with respect to Issuer pursuant to this Section 3, the Holder shall be required
to enter into customary

                                       3
<PAGE>
 
agreements (including an underwriting agreement in customary form) and take such
other actions as are reasonably required by the underwriters in order to include
the Registrable Securities for sale pursuant to such underwritten offering.

          (d) Issuer represents and warrants that, as of the date hereof, no
other securityholder of Issuer has been granted "piggy-back" registration
rights.

4.   Holdback Agreements

          (a) Restrictions on Public Sale Holder of Registrable Securities.  To
the extent not inconsistent with applicable law, each Holder whose securities
are included in a registration statement pursuant to Section 3 agrees not to
effect any public sale or distribution of the issue being registered or a
similar security of Issuer, or any securities convertible into or exchangeable
or exercisable for such securities, including a sale pursuant to Rule 144 under
the Act, during the fourteen (14) days prior to, and during the ninety-day
period beginning on, the effective date of such registration statement (except,
in each case, as part of such registration), if and to the extent requested by
the managing underwriter or underwriters.

          (b) Postponement of Sale under Shelf Registration Statement.  Each
Holder agrees not to effect any public sale or distribution pursuant to any
Shelf Registration pursuant to this Agreement at any time that Issuer shall have
advised the Holders in writing that the sale by such Holders pursuant to such
Shelf Registration could reasonably be expected to (i) adversely affect, or
require the premature disclosure of any proposed acquisition, disposition or
other transaction involving Issuer or (ii) materially and adversely affect any
proposed underwritten public offering of Amerac Common Stock if the managing
underwriter thereof shall have advised the Holders that any such sales could
reasonably be expected to jeopardize the success of the offering; provided,
however, in each such case Issuer may not restrict any such sales unless at
least five days prior written notice is provided to each Holder and provided
further Issuer may not restrict sales by Holders (x) for a total of more than 90
days during any one-year period or (y) for more than 60 consecutive days after
the date of the prospectus for any such underwritten public offering.

5.   Registration Procedures

          Whenever Registrable Securities are required to be registered pursuant
to Section 3 hereof, Issuer will use its best efforts to effect the registration
and the sale of such Registrable Securities in accordance with the intended
method of disposition thereof as quickly as practicable, and in connection with
any such request and with the Shelf Registration, Issuer will, as expeditiously
as possible:

          (a) (i) prior to filing a registration statement or prospectus or any
amendments or supplements thereto, furnish to one counsel selected by the
Holders of a majority of the Registrable Securities covered by such registration
statement copies of all such documents proposed to be filed, which documents
will be subject to the review of such counsel, (ii) as soon as reasonably
possible, furnish to each Selling Holder, prior to filing a registration
statement,

                                       4
<PAGE>
 
copies of such registration statement as proposed to be filed, and thereafter
furnish to such Selling Holder such number of copies of such registration
statement, each amendment and supplement thereto (in each case including all
exhibits thereto), the prospectus included in such registration statement
(including each preliminary prospectus) and such other documents as such Selling
Holder may reasonably request in order to facilitate the disposition of the
Registrable Securities owned by such Selling Holder, and (iii) after the filing
of the registration statement, promptly notify each Selling Holder of
Registrable Securities covered by such registration statement of any stop order
issued or threatened by the Commission and take all reasonable actions required
to prevent the entry of such stop order or to remove it if entered;

          (b) prepare and file with the Commission such amendments and post-
effective amendments to the registration statement as may be necessary to keep
the registration statement effective for (i) a period of not less than nine (9)
months in the case of a registration statement on Forms S-1 or S-2, or (ii) an
indefinite period in the case of a registration statement on Form S-3 (or such
shorter period which will terminate when all Registrable Securities covered by
such registration statement have been sold or withdrawn, but not prior to the
expiration of the 25-day period referred to in Section 4(3) of the Act and Rule
174 thereunder, if applicable); cause the prospectus to be supplemented by any
required prospectus supplement, and as so supplemented to be filed pursuant to
Rule 424 under the Act; and comply with the provisions of the Act applicable to
it with regard to the disposition of all securities covered by such registration
statement during the applicable period in accordance with the intended methods
of disposition by the sellers thereof set forth in such registration statement
or supplement to the prospectus;

          (c) if requested by the managing underwriter or underwriters or any
Holder of Registrable Securities covered by the registration statement, promptly
incorporate in a prospectus supplement or post-effective amendment such
information as the managing underwriter or underwriters or such holder, as the
case may be, reasonably requested to be included therein, including, without
limitation, information with respect to the number of Registrable Securities
being sold by such holder to an underwriter or underwriters, the purchase price
being paid therefor by such underwriter or underwriters and with respect to any
other terms of the underwritten offering of the Registrable Securities to be
sold in such offering, and promptly make all required filings of such prospectus
supplement or post-effective amendment;

          (d) enter into such customary agreements (including an underwritten
agreement in customary form with provisions as may be reasonably required by the
managing underwriter retained by the holder of Registrable Securities) and take
all such other actions as the holders of a majority of the Registrable
Securities being sold or the managing underwriter or underwriters retained by
holders participating in an underwritten public offering, if any, reasonably
request in order to expedite or facilitate the disposition of such Registrable
Securities in each case to the same extent as if all the securities then being
offered were for the account of the Company;

          (e) use its best efforts to register or qualify such Registrable
Securities under such other securities or blue sky laws of such jurisdictions as
any Selling Holder reasonably requests and do any and all other acts and things
which may be reasonably necessary or advisable to enable such Selling Holder to
consummate the disposition in such jurisdictions of the

                                       5
<PAGE>
 
Registrable Securities owned by such Selling Holder; provided that Issuer will
not be required to (i) qualify generally to do business in any jurisdiction
where it would not otherwise be required to qualify but for this paragraph (b),
(ii) subject itself to taxation or qualification in any such jurisdiction or
(iii) consent to general service of process in any such jurisdiction;

          (f) notify each Selling Holder of such Registrable Securities, at any
time when a prospectus relating thereto is required to be delivered under the
Act, of the occurrence of an event requiring the preparation of a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such prospectus will not contain an untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading and
promptly make available to each Selling Holder any such supplement or amendment;

          (g) enter into customary agreements (including an underwriting
agreement in customary form) and take such other actions as are reasonably
required in order to expedite or facilitate the disposition of such Registrable
Securities;

          (h) make available for inspection on a confidential basis by any
Selling Holder of such Registrable Securities, any underwriter participating in
any disposition pursuant to such registration statement, and any attorney,
accountant or other professional retained by any such Selling Holder or
underwriter (collectively, the "Inspectors"), all financial and other records,
pertinent corporate documents and properties of Issuer and its subsidiaries
(collectively, the "Records") as shall be reasonably necessary to enable them to
exercise their due diligence responsibility, and cause Issuer's and its
subsidiaries' officers, directors and employees to supply all information
reasonably requested by any such Inspector in connection with such registration
statement;

          (i) in the event such sale is pursuant to an underwritten offering,
use its best efforts to obtain a comfort letter or comfort letters from Issuer's
independent public accountants in customary form and covering such matters of
the type customarily covered by comfort letters as the Selling Holders of a
majority in aggregate principal amount or number of shares, as the case may be,
of the Registrable Securities being sold or the managing underwriter reasonably
request and an opinion of outside counsel to Issuer covering such matters as are
customarily covered by such opinions;

          (j) otherwise use its best efforts to comply with all applicable rules
and regulations of the Commission, and make available to its securityholders, as
soon as reasonably practicable, an earnings statement covering a period of 12
months, beginning within three months after the effective date of the
registration statement, which earnings statement shall satisfy the provisions of
Section 11(a) of the Act; and

          (k) use its best efforts to cause all such Registrable Securities to
be listed on each securities exchange on which the Common Stock of Issuer is
then listed.

                                       6
<PAGE>
 
          Issuer may require each Selling Holder of Registrable Securities as to
which any registration is being effected to furnish to Issuer such information
regarding the distribution of such Registrable Securities as Issuer may from
time to time reasonably request in writing and such other information as may be
legally required in connection with such registration.

          Each Selling Holder agrees that, upon receipt of any notice from
Issuer of the happening of any event of the kind described in Section 5(c)
hereof, such Selling Holder will forthwith discontinue disposition of
Registrable Securities pursuant to the registration statement covering such
Registrable Securities until such Selling Holder's receipt of the copies of the
supplemented or amended prospectus contemplated by Section 5(c) hereof, and, if
so directed by Issuer, such Selling Holder will deliver to Issuer (at Issuer's
expense) all copies, other than permanent file copies, of the prospectus
covering such Registrable Securities current at the time of receipt of such
notice.  In the event Issuer shall give any such notice, Issuer shall extend the
period during which such registration statement shall be maintained effective
(including the period referred to in Section 2(b) hereof) by the number of days
during the period from and including the date of the giving of such notice
pursuant to Section 5(c) hereof to and including the date when each Selling
Holder of Registrable Securities covered by such registration statement shall
have received the copies of the supplemented or amended prospectus contemplated
by Section 5(c) hereof.

6.   Registration Expenses

          Except as provided in Section 2(b) hereof, all expenses incident to
Issuer's performance of or compliance with this Agreement, including without
limitation all registration and filing fees, fees and expenses of compliance
with securities or blue sky laws (including reasonable fees and disbursements of
counsel in connection with blue sky qualifications of the Registrable
Securities), printing expenses, messenger and delivery expenses, the fees and
expenses incurred in connection with the listing of the securities to be
registered on any securities exchanges and fees and disbursements of counsel for
Issuer and its independent certified public accountants (including the expenses
of any special audit or comfort letters required by or incident to such
performance), securities acts liability insurance (if Issuer elects to obtain
such insurance) and the reasonable fees and expenses of any special experts
retained by Issuer in connection with such registration, fees and expenses of
other persons retained by Issuer (all such expenses being herein called
"Registration Expenses"), will be borne by Issuer.  Registration Expenses shall
not include the fees and expenses of any counsel for the Holders, any
underwriting discounts, commissions, or similar charges attributable to the sale
of Registrable Securities or any other expenses of the Holders, all of which
shall be paid by the Holders.

7.   Indemnification; Contribution

          (a) Indemnification by Issuer.  Issuer agrees to indemnify and hold
harmless each Selling Holder, its officers, directors, partners and agents and
each person, if any, who controls such Selling Holder within the meaning of
Section 15 of the Act or Section 20 of the Securities Exchange Act of 1934, as
amended, from and against any and all losses, claims, damages (whether in
contract, tort or otherwise), liabilities and expenses (including reasonable

                                       7
<PAGE>
 
costs of investigation) whatsoever (as incurred or suffered) arising out of or
based upon any untrue statement or alleged untrue statement of a material fact
contained in any registration statement or prospectus relating to the
Registrable Securities or in any amendment or supplement thereto or in any
preliminary prospectus, or arising out of or based upon any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, except insofar as such
losses, claims, damages, liabilities or expenses arise out of, or are based
upon, any such untrue statement or omission or allegation thereof based upon
information furnished in writing to Issuer by such Selling Holder or on such
Selling Holder's behalf expressly for use therein.  Issuer also agrees to
indemnify any underwriters of the Registrable Securities, their officers,
partners and directors and each person who controls such underwriters on
substantially the same basis as that of the indemnification of the Selling
Holders provided in this Section 7 or such other indemnification customarily
obtained by underwriters at the time of offering.

          (b) Conduct of Indemnification Proceedings.  If any action or
proceeding (including any governmental investigation) shall be brought or
asserted against any Selling Holder (or its officers, directors, partners or
agents) or any person controlling any such Selling Holder in respect of which
indemnity may be sought from Issuer, Issuer shall, at its expense, assume the
defense thereof, including the employment of counsel reasonably satisfactory to
such Selling Holder.  Such Selling Holder or any controlling person of such
Selling Holder shall have the right to employ separate counsel in any such
action and to participate in the defense thereof, but the fees and expenses of
such counsel shall be at the expense of such Selling Holder or such controlling
person unless (i) Issuer has agreed to pay such fees and expenses or (ii) the
named parties to any such action or proceeding (including any impleaded parties)
include both such Selling Holder or such controlling person and Issuer, and such
Selling Holder or such controlling person shall have been advised by counsel
that there may be one or more legal defenses available to such Selling Holder or
such controlling person which are different from or additional to those
available to Issuer (in which case, if such Selling Holder or such controlling
person notifies Issuer in writing that it elects to employ separate counsel at
the expense of Issuer, Issuer shall not have the right to assume the defense of
such action or proceeding on behalf of such Selling Holder or such controlling
person; it being understood, however, that Issuer shall not, in connection with
any one such action or proceeding or separate but substantially similar or
related actions or proceedings in the same jurisdiction arising out of the same
general allegations or circumstances, be liable for the fees and expenses of
more than one separate firm of attorneys (together with appropriate local
counsel) at any time for all the Selling Holders and such controlling persons,
which firm shall be designated in writing by a majority of the Selling Holders).
Issuer shall not be liable for any settlement of any such action or proceeding
effected without Issuer's written consent, but if settled with its written
consent, or if there be a final judgment no longer subject to appeal for the
plaintiff in any such action or proceeding, Issuer agrees to indemnify and hold
harmless such Selling Holder and such controlling person from and against any
loss or liability (to the extent stated above) by reason of such settlement or
judgment.

          (c) Indemnification by Holders of Registrable Securities.  Each
Selling Holder agrees, severally but not jointly, to indemnify and hold harmless
Issuer, its directors and officers and each person, if any, who controls Issuer
within the meaning of either Section 15 of the Act

                                       8
<PAGE>
 
or Section 20 of the Securities Exchange Act of 1934, as amended, to the same
extent as the foregoing indemnity from Issuer to such Selling Holder, but only
with respect to information furnished in writing by such Selling Holder or on
such Selling Holder's behalf expressly for use in any registration statement or
prospectus relating to the Registrable Securities, or any amendment or
supplement thereto, or any preliminary prospectus.  In case any action or
proceeding shall be brought against Issuer or its directors or officers, or any
such controlling person, in respect of which indemnity may be sought against
such Selling Holder, such Selling Holder shall have the rights and duties given
to Issuer, and Issuer or its directors or officers or such controlling person
shall have the rights and duties given to such Selling Holder, by the preceding
paragraph.  Each Selling Holder also agrees to indemnify and hold harmless
underwriters of the Registrable Securities, their officers and directors and
each person who controls such underwriters on substantially the same basis as
that of the indemnification of Issuer provided in this Section 7.

          (d) Contribution.  If the indemnification provided for in this Section
7 is unavailable to Issuer, the Selling Holders or the underwriters in respect
of any losses, claims, damages, liabilities or judgments referred to herein,
then each such indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities and judgments (i) as
between Issuer and the Selling Holders on the one hand and the underwriters on
the other, in such proportion as is appropriate to reflect the relative benefits
received by Issuer and the Selling Holders on the one hand and the underwriters
on the other from the offering of the Registrable Securities, or if such
allocation is not permitted by applicable law, in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of Issuer and the Selling Holders on the one hand and of the underwriters
on the other in connection with the statements or omissions which resulted in
such losses, claims, damages, liabilities or judgments, as well as any other
relevant equitable considerations and (ii) as between Issuer, on the one hand,
and each Selling Holder on the other, in such proportion as is appropriate to
reflect the relative fault of Issuer and of each Selling Holder in connection
with such statements or omissions, as well as any other relevant equitable
considerations.  The relative benefits received by Issuer and the Selling
Holders on the one hand and the underwriters on the other shall be deemed to be
in the same proportion as the total proceeds from the offering (net of
underwriting discounts and commissions but before deducting expenses) received
by Issuer and the Selling Holders bear to the total underwriting discounts and
commissions received by the underwriters, in each case as set forth in the table
on the cover page of the prospectus.  The relative fault of Issuer and the
Selling Holders on the one hand and of the underwriters on the other shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by Issuer and the Selling
Holders or by the underwriters.  The relative fault of Issuer on the one hand
and of each Selling Holder on the other shall be determined by reference to,
among other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates to
information supplied by such party, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such statement or
omission.

                                       9
<PAGE>
 
          Issuer and the Selling Holders agree that it would not be just and
equitable if contribution pursuant to this Section 7(d) were determined by pro
rata allocation (even if the underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to in the immediately preceding paragraph.
The amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities, or judgments referred to in the immediately
preceding paragraph shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this Section 7(d), no underwriter shall be
required to contribute any amount in excess of the amount by which the total
price at which the Registrable Securities underwritten by it and distributed to
the public were offered to the public exceeds the amount of any damages which
such underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission, and no Selling Holder
shall be required to contribute any amount in excess of the amount by which the
total price at which the Registrable Securities of such Selling Holder were
offered to the public exceeds the amount of any damages which such Selling
Holder has otherwise been required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission.  No person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
shall be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation.  Each Selling Holder's obligation to contribute is
several in the proportion that the proceeds of the offering received by such
Selling Holder bears to the total proceeds of the offering, and not joint.

          (e) Limitation of Liability.  In no event shall any Selling Holder be
liable under this Section 7 or otherwise in respect of any offering for amounts
in excess of the net proceeds received by such Selling Holder from the sale of
Registrable Securities in such offering.

8.   Participation in Underwritten Registrations

          No person may participate in any underwritten registration hereunder
unless such person (a) agrees to sell such person's securities on the basis
provided in any underwriting arrangements approved by the persons entitled
hereunder to approve such arrangements and (b) completes and executes all
questionnaires, powers of attorney, indemnities, underwriting agreements and
other documents reasonably required under the terms of such underwriting
arrangements and this Agreement.

9.   Rule 144.

          Issuer covenants that it will file any reports required to be filed by
it under the Act and the Securities Exchange Act of 1934, as amended, and that
it will take such further action as any Holder may reasonably request, all to
the extent required from time to time to (i) maintain its eligibility to use
Form S-3 under the Act to register the Registrable Securities and (ii) enable
Holders to sell Registrable Securities without registration under the Act within
the limitation of the exemptions provided by (a) Rule 144 under the Act, as such
Rule may be amended from time to time, or (b) any similar rule or regulation
hereafter adopted by the Commission.  Upon the

                                       10
<PAGE>
 
request of any Holder, Issuer will deliver to such Holder a written statement as
to whether it has complied with such requirements.

10.  Transfer of Registration Rights

          The registration rights provided to the Holders of the Registrable
Securities under Sections 2 and 3 hereof may be transferred in whole or in part
to any other person in connection with a transfer of all or any portion of
Registrable Securities that complies with the Act and any applicable state
securities or blue sky laws.  Any such transferee of Registrable Securities who
is also a transferee of the registration rights provided under Sections 2 and 3
hereof shall be a Holder of Registrable Securities within the meaning of this
