ITEM 5.  OTHER EVENTS

         Queen Sand Resources, Inc. (the "Company") has executed a definitive
purchase and sale agreement (the "Agreement") to acquire certain non-operated
royalty and net profits overriding royalty interests from two commingled pension
trust funds for which Morgan Guaranty Trust Company of New York serves as
trustee. The purchase price is $150 million in cash subject to standard closing
adjustments for net production revenues since October 1, 1997 and capital
expenditures incurred since that date. The Company has made a non-refundable
deposit of $15 million under the Agreement. The effective date of the
transaction is October 1, 1997 with an anticipated closing on or before April
22, 1998. Bank of Montreal and affiliates of Enron Corp. have provided a
commitment for $156 million in bridge financing to be funded on closing. The
obligation of the lenders to fund under the commitments is subject to
satisfaction of customary conditions precedent, including, but not limited to,
negotiation, execution and delivery of definitive lending documentation
containing customary representations, covenants, conditions and other terms.
There is no assurance this will be accomplished on terms acceptable to the
Company.

         The acquisition encompasses interests in over 530 wells in
approximately 40 different fields located primarily in East Texas, South Texas
and the Mid-continent area. The Company's independent engineers, Ryder Scott
Company, estimate that total proved reserves consist of approximately 127.7
billion cubic feet (bcf) of natural gas and 3.7 million barrels of oil. The
reserves are approximately 85% natural gas, having an estimated
reserve-to-production ratio of over 10 years, and 80% are classified by Ryder
Scott Company as proved developed producing. The non-operated royalty and net
profits overriding royalty interests in the various properties range from 2% to
80%.

         The Company has purchased an option to enter into a swap, hedging the
natural gas production of the Company over the next 5 years at $2.15 per mmbtu.
The Company expects to replace this option with a comprehensive hedging strategy
prior to the expiry of the option on May 1, 1998.

         The information in this Current Report on Form 8-K includes certain
forward-looking statements that are based on assumptions that in the future may
prove not to have been accurate. These statements, and the Company's business
and prospects, are subject to a number of risks, including production variances
from expectations, uncertainties about estimates of reserves, volatility of oil
and natural gas prices, the need to develop and replace its reserves, the
substantial capital expenditures required to fund its operations, environmental
risks, drilling and operating risks, risks related to exploratory and
developmental drilling, competition, government regulation, and the ability of
the Company to implement its business strategy. These and other risks are
described in the Company's Annual Report on Form 10-KSB for the year ended June
30, 1997, which report is available from the Company and the Securities and
Exchange Commission.

         2.1 PURCHASE PRICE. The purchase price for the Assets (the "Purchase
Price") shall be $150,000,000 in cash (subject to the provisions of Section 3.3)
payable at the Closing (subject to the provisions of Sections 2.3 and 2.4). The
payment of the Purchase Price (subject to the provisions of Sections 2.3 and
2.4) shall be made on the Closing Date by wire transfer of immediately available
funds to an account to be designated by Sellers at lease three (3) business days
prior to the scheduled Closing Date to be received in time for investment of
such funds on the Closing Date; provided, the portion of such funds constituting

         2.2 LAREDO RANCH PROPERTY ESCROW. (a) Purchaser represents that it has
fully reviewed the allegations asserted by Plaintiff (the "Plaintiff") in Lannie
Mecom f/k/a/ Lannie Mecom Moses v. Vinson & Elkins, et al; Cause No. 96-25436,
formerly in the 80th Judicial District Court of Harris County, Texas and now on
appeal (the "Case") and recognizes that if Plaintiff is successful in the Case,
it may be necessary for Sellers to convey to Plaintiff the Royalty Interest
described under item 15 on Exhibit D (the "Laredo Ranch Royalty") which
constitutes a part of the Assets.

         (b) Purchaser and Seller II hereby appoint Chase Bank of Texas,
National Association as Escrow Agent (the "Escrow Agent") to perform the
functions delegated to Escrow Agent in this Section 2.2 and the Escrow Agreement
attached hereto as Exhibit H. To the extent this Section 2.2 and the Escrow
Agreement are in conflict, the Escrow Agreement shall control.

         (c) If Escrow Agent for any reason should be unable or refuse to serve
as Escrow Agent, Seller II and Purchaser shall attempt to agree on another
Escrow Agent. If they cannot agree within 30 days after the Escrow Agent
notifies them of its inability or refusal to serve, either Seller II or
Purchaser may petition the most senior judge of the United States District Court
for the Southern District of Texas, Houston Division (the "Court"), to appoint a
successor Escrow Agent. The

                                        4

<PAGE>   12



successor Escrow Agent, appointed either by the agreement of Seller II and
Purchaser or by the Court, shall have the same duties and responsibilities as
the initial Escrow Agent. Any number of successor Escrow Agents may be appointed
in accordance with the procedure set forth above until all duties and
responsibilities of the Escrow Agent are completed. The fees and costs of the
initial Escrow Agent and the successor Escrow Agents, if any, shall be shared
equally by Seller II and Purchaser.

         (d) On the Closing Date, Purchaser, as part of and out of the Purchase
Price, shall pay to Escrow Agent $8,000,000 ("Escrow Amount") by wire transfer
of immediately available funds to an account ("Escrow Account") designated by
Escrow Agent to be received in time for investment of such funds on the Closing
Date. The Escrow Amount shall be subject to reduction pursuant to Section 3.3,
but only to the extent the reduction results from a Title Defect related solely
to the Laredo Ranch Royalty. All matters relating to the Case, including any lis
pendens notice, shall not constitute Title Defects. The Escrow Agent shall hold
and invest the Escrow Amount in accordance with this Agreement and the Escrow
Agreement. The Escrow Amount and all investment earnings thereon (net of
investment expenses) shall be invested and reinvested by the Escrow Agent in
Vista Treasury Plus Money Market Fund or such similar investments as may be
approved in writing by Seller II and Purchaser.

         (e) At Closing, Purchaser shall execute and deliver to Escrow Agent a
conveyance from Purchaser to Seller II of the Laredo Ranch Royalty (the
"Reconveyance") on the form attached hereto as Exhibit I and Seller II,
Purchaser and Escrow Agent shall execute a memorandum (the "Memorandum") on the
form attached hereto as Exhibit J to be recorded in the real property records of
Zapata County, Texas by Seller II in which all three agree and confirm that
Escrow Agent is holding for the benefit of Seller II the Reconveyance and that
any and all subsequent transfers of the Laredo Ranch Royalty or the property
encumbered thereby shall be are subject to and inferior to the Reconveyance.
Seller II and Purchaser acknowledge and agree that the Reconveyance shall not be
deemed to be "delivered" (under Texas conveyancing law) until such time (if
ever) that the Reconveyance is released from escrow and delivered by Escrow
Agent to Seller II.

         (f) At such time as an unappealable final judgment or an order of
dismissal is rendered in the Case as against Seller II as a defendant
("Judgment"), either Seller II or Purchaser may deliver to the Escrow Agent a
certified copy of the Judgment. If in the Judgment Seller II is not ordered to
convey the Laredo Ranch Royalty to Plaintiff, then either Seller II or Purchaser
may instruct the Escrow Agent to immediately:

             (i)  deliver to Purchaser the Reconveyance and execute and record
                  in the real property records of Zapata County, Texas, a
                  memorandum acknowledging and confirming that the Reconveyance
                  has been redelivered to Purchaser; and

             (ii) deliver to Seller II the Escrow Amount and all income thereon.

         (g) If in the Judgment Seller II is ordered to convey the Laredo Ranch
Royalty to Plaintiff, then:

             (i)  within five business days following Purchaser's receipt of a
                  certified copy of the Judgment (a copy of the Judgment to be
                  provided to the Escrow Agent on the same date), Purchaser
                  shall provide or cause to be provided to Escrow

                  Agent and Seller II a statement reflecting the gross revenues
                  received by Purchaser (or any successor holder of all or any
                  part of the Laredo Ranch Royalty) from the Laredo Ranch
                  Royalty, and all severance and ad valorem taxes and
                  compression costs relating to the Laredo Ranch Royalty during
                  the same period, together with copies of receipts, invoices
                  and other documentation reasonably supporting such revenues,
                  taxes and compression costs over such period;

             (ii) within six business days following the Escrow Agent's receipt
                  of a copy of the Judgment, either Seller II or Purchaser may
                  instruct the Escrow Agent to insert the date of the Judgment
                  in the Reconveyance as the delivery date of such instrument
                  and deliver to Seller II the Reconveyance; and

            (iii) within two business days following the receipt of the
                  information described in clause (i), either Seller II or
                  Purchaser may instruct the Escrow Agent to deliver to
                  Purchaser (1) the total amount contained in the Escrow Account
                  less (2) the total net revenues (gross revenues less severance
                  and ad valorem taxes and compression costs) received by
                  Purchaser (or successor holders of all or any part of the
                  Laredo Ranch Royalty) from the Laredo Ranch Royalty and to
                  deliver to Seller II all (if any) remaining funds in the
                  Escrow Account. If the amount determined pursuant to clause
                  (2) preceding exceeds the amount determined pursuant to clause
                  (1) preceding, then Purchaser shall pay such excess amount to
                  Seller II no later than five business days following
                  Purchaser's receipt of a copy of the Judgment. In addition, to
                  the extent that Purchaser or any successor holder of all or
                  any part of the Laredo Ranch Royalty receives net revenues
                  attributable to the Laredo Ranch Royalty and such revenues
                  have not been included in the calculation pursuant to clause
                  (2) preceding, then such net revenues shall be paid to Seller
                  II by Purchaser no later than ten days following Purchaser's
                  receipt of the same. For purposes of this clause (iii) and the
                  preceding clause (i), Purchaser shall be deemed to have
                  received (without duplication) those revenues relating to the
                  Laredo Ranch Royalty (less the Expenses relating to the Laredo
                  Ranch Royalty) that are allocated to Purchaser pursuant to
                  Section 2.3, in each case as reflected on the Final Closing
                  Statement.

         (h) The obligations of Purchaser and rights of Seller II pursuant to
this Section 2.2 shall not be modified or effected by any assignment or
encumbrance by Purchaser of all or any part of the Laredo Ranch Royalty; rather,
Purchaser shall remain primarily liable for the obligations pursuant to this
Section 2.2 and Seller II shall not be required (without their written consent)
to deal with any such successor holder.

         (i) If Purchaser should become a party to the Case after Closing, then
Seller II and Purchaser agree to act in good faith and with due diligence in
cooperating in all of the same or similar defenses in the Case. Subject to
Purchaser providing appropriate waiver of any conflict issues, Seller II shall
exercise its reasonable efforts to cause Purchaser to be represented by Seller
II's counsel in the Case.

         2.3 REVENUES, EXPENSES AND ANCILLARY PAYMENTS. (a) Reference is made to
the fact that pursuant to each Conveyance for an Overriding Royalty Interest the
Net Cash Flow Accounts are maintained on a cash versus accrual basis, and as a
result thereof (i) revenue from the sale of production is not credited to the
Net Cash Flow Account until received by the Assignor and (ii) Expenses incurred
by the Assignor are not debited to the Net Cash Flow Account until paid by the
Assignor. Pursuant to this Agreement, Sellers and Purchaser agree that
notwithstanding the fact that the Net Cash Flow Accounts are maintained on a
cash basis, for purposes of this Agreement Seller shall be entitled to
production attributable to each Royalty Interest and Overriding Royalty Interest
for periods prior to the Effective Time and to the revenue from the sale of such
production (regardless of when such revenue is credited to the Net Cash Flow
Account or otherwise paid) and that Expenses and the taxes described in Sections
12.1 and 12.3 attributable to each Overriding Royalty Interest and Royalty
Interest that are incurred or (as to such taxes) are attributable to the period
prior to the Effective Time shall be for the account of Sellers (regardless of
when such Expenses and taxes are debited to the Net Cash Flow Account); and that
Purchaser shall be entitled to production attributable to each Royalty Interest
and Overriding Royalty Interest for periods following the Effective Time and to
the revenue from the sale of such production (regardless of when such revenue is
credited to the Net Cash Flow Accounts or otherwise paid) and that Expenses and
the taxes described in Sections 12.1 and 12.3 attributable to each Overriding
Royalty Interest and Royalty Interest that are incurred or (as to such taxes)
are attributable to the period following the Effective Time shall be for the
account of Purchaser (regardless of when such Expenses and taxes are debited to
the Net Cash Flow Account). By way of example, (i) if an environmental condition
exists as of the Effective Time but the applicable Assignor does not make any
expenditures for the remediation of such environmental condition until after the
Effective Time, then to the extent such expenditures constitute Expenses such
expenditures shall constitute Expenses incurred after the Effective Time, and
(ii) if as of the Effective Time an Assignor has commenced but not completed the
workover of a well, the remediation of an environmental condition or some other
action that gives rise to an Expense, then the cost incurred by such Assignor
with respect to such workover, remediation or other action prior to the
Effective Time shall be for the account of Seller and the cost incurred by
Assignor with respect to such workover, remediation or other action following
the Effective Time shall be for the account of Purchaser. For purposes of the
preceding provisions, with respect to the Overriding Royalty Interests Seller
and Purchaser acknowledge that the taxes referenced in Sections 12.1 and 12.3
are typically treated as Expenses under the Conveyances and debited to the Net
Cash Flow Accounts following payment by the Assignor, and that the taxes
referenced in Section 12.1 are typically paid by the Assignor in one lump sum on
an annual basis. The reference in the preceding provisions that certain Expenses
are for the account of Sellers or Purchaser shall not by implication or
otherwise constitute any agreement on the part of Sellers or Purchaser to become
directly or personally liable for such Expenses; rather, such references are to
be used solely for the purpose of making the calculations required pursuant to
this Agreement. By way of clarification, the parties agree that the Net Cash
Flow deficits identified in clause (i) through (iv) of item 2 of the Disclosure
Letter shall constitute pre-Effective Time Expenses and that the Net Cash Flow
Deficits identified in clause (v) of item 2 of the Disclosure Letter shall not
constitute Expenses.

         (b) In connection with the Overriding Royalty Interests Sellers entered
into and are parties to the Ancillary Agreements and Specified Agreements.
Pursuant to the Ancillary Agreements the "Assignee" party thereunder is, under
certain conditions specified therein, required to pay deferred purchase price
for the Overriding Royalty Interests (the "Ancillary Payments"). Pursuant to the
Assumption Agreement, Purchaser shall assume and be obligated to bear and pay






                                        7

<PAGE>   15



all Ancillary Payments that are attributable to the period following the
Effective Time and those Ancillary Payments (the "Exception Payments") that are
attributable to operations commenced (or as to which Seller has elected to
participate in) prior to the Effective Time and which are covered by the Ryder
Scott Report; and Sellers shall remain liable for and shall pay all Ancillary
Payments that are attributable to the period prior to the Effective Time
excluding the Exception Payments. For purposes of this Agreement, amounts
invoiced under any Conveyance with respect to leases and other interests in
which Morgan has elected to purchase an overriding royalty interest pursuant to
the area of mutual interest provisions set forth in such Conveyance also shall
constitute an Ancillary Payment, and Purchaser shall assume and be obligated to
bear and pay all such amounts invoiced after the Effective Time and Sellers
shall remain liable for and shall pay all such amounts invoiced prior to the
Effective Time. By way of clarification, the parties agree that (i) Ancillary
Payments attributable to the period prior to the Effective Time shall include
Deferred ORI Purchase Price amounts for wells drilled and operations performed
prior to the Effective Time (and the parties stipulate and agree that costs
incurred for the drilling, completing and equipping the Ramirez wells described
below shall be deemed to be attributable to the period prior to the Effective
Time) even though the applicable Assignor has not yet sent a bill for such
amounts and (ii) if the operator of the Ramirez wells (being those wells
identified as Well Nos. 3, 4 and 5 on the Josefa Ramirez lease identified on
Exhibit C sets-off against proceeds of post-Effective Time production from such
wells any claims of such operator with respect to pre-Effective Time events or
operations (the "Deferred Cost Amounts"), then to the extent such set-offs cover
Deferred Cost Amounts, such set-offs shall constitute an Ancillary Payment and
Morgan shall pay the same to Purchaser within ten (10) days following a receipt
of an invoice from Purchaser reflecting such set-offs and the corresponding
Deferred Cost Amounts in reasonable detail; provided, in no event shall the
total of amounts payable by Morgan pursuant to this clause (ii) exceed $980,000.
Any such payments from Morgan to Purchaser shall be without prejudice or waiver
of Morgan's right to recover any Deferred Cost Amounts from the operator if the
basis or amount of such Deferred Cost Amounts are invalid or if the operator
otherwise improperly exercised the right of set-off.

         (c) No later than three business days preceding the Closing Date,
Sellers shall prepare (or cause to be prepared) a preliminary closing statement
("Preliminary Closing Statement") that covers the Assets and that is in
accordance with the requirements of Sections 2.3(a) and (b). The Preliminary
Closing Statement shall identify (i) as to each Royalty Interest, all payments
received by any Seller with respect to such Royalty Interest following the
Effective Time and a breakdown of the amount of such revenues attributable to
pre-Effective Time production and the amount of such revenues attributable to
post-Effective Time production, (ii) as to each Overriding Royalty Interest, all
payments of Net Cash Flow received by any Seller following the Effective Time
and all Ancillary Payments made by any Seller following the Effective Time, and
(iii) a reconciliation between the information referenced in the preceding
clauses (i) and (ii) and the amount of revenue to which each party is entitled
and the amount of Expenses, taxes and Ancillary Payments allocated to each party
pursuant to the terms of Sections 2.3(a) and (b).

         (d) If the Preliminary Closing Statement reflects a net positive amount
in favor of Purchaser, then at the Closing Purchaser shall receive a credit
against the Purchase Price in an amount equal to such net positive amount. If
the Preliminary Closing Statement reflects a net positive amount in favor of
Sellers, then at the Closing Sellers shall be entitled to receive from
Purchaser, in addition to the Purchase Price, a payment in an amount equal to
such net positive amount.



                                        8

         (e) If following the Closing any funds are received by Sellers or
Purchaser that, under the terms of this Section 2.3, belong to the other party,
the receiving party shall, as soon as reasonably practicable and in all events
within 30 days after receipt, pay such funds over to the other party.

         2.4 DEPOSIT. (a) On even date herewith, Purchaser has paid to Sellers,
and Sellers acknowledge receipt of, a performance deposit in the amount of 10%
of the Purchase Price (the "Deposit"), which amount shall be held by Sellers and
distributed as follows:

             (i)  if this Agreement is terminated by mutual consent of the
         parties as provided in Section 11.1(a) or by Sellers or Purchaser 
         pursuant to Section 11.1(b), the Deposit shall be returned by Sellers 
         to Purchaser;

             (ii) if this Agreement is terminated by Purchaser pursuant to
         Section 11.1(c), the Deposit shall be returned by Sellers to Purchaser;

             (iii) if this Agreement is terminated by Sellers pursuant to
         Section 11.1(c), the Deposit shall be retained by Sellers; and

             (iv) if Closing occurs, Sellers shall apply the Deposit towards the
         Purchase Price.

Sellers and Purchaser acknowledge and agree that until Sellers are obligated to
distribute the Deposit as provided above, Sellers may invest the Deposit in such
investments as it deems appropriate and any income resulting therefrom in excess
of the Interest Rate shall be the property of Sellers and not Purchaser; it
being agreed that if Sellers are obligated to return the Deposit to Purchaser or
apply same towards the Purchase Price pursuant to the preceding provisions,
Sellers shall also pay or credit Purchaser for an additional amount equal to
interest on the Deposit at the Interest Rate for the period beginning on the
date hereof and ending on the date the Deposit is returned to Purchaser or so
applied to the Purchase Price.

         (b) Purchaser further acknowledges and agrees that if Sellers become
entitled to the Deposit pursuant to the provisions of Section 2.4(a), Seller's
damages under such circumstances would be difficult to ascertain and Sellers
shall be entitled to liquidated damages in an amount equal to the Deposit.
Accordingly, the retention by Sellers of the Deposit as provided in Section
2.4(a) shall be deemed to constitute the payment by Purchaser to Sellers of such
liquidated damages, but in no event shall such retention of the Deposit or
deemed payment of liquidated damages constitute or be construed as a penalty. If
Sellers become entitled to retain the Deposit pursuant to Section 2.1(c)(iii)
above, such retention shall constitute the sole remedy of Sellers under this
Agreement for Purchaser's failure to consummate the transactions contemplated
hereunder (such limitation shall not limit the rights of Sellers under any of
the provisions of this Agreement that survive a termination and continue in full
force and effect pursuant to Section 11.2).

         2.5 POST-CLOSING SETTLEMENT STATEMENT. Within 60 days following the
Closing, Purchaser shall prepare a post-closing settlement statement in a manner
consistent with Sections 2.3(a) and (b) and otherwise consistent with the manner
in which the Preliminary Closing Statement was prepared and the aforesaid
statement shall include a reconciliation with the Preliminary Closing Statement.
Within 30 days after receipt of such statement from Purchaser, Sellers shall
deliver to Purchaser a written report containing all changes with explanations
therefore that Sellers propose




                                        9

<PAGE>   17



to be made to such statement, it being agreed that Sellers failure to deliver
such report to Purchaser within such time period shall constitute acceptance by
Sellers of such statement. If Sellers have timely delivered such written report,
the parties shall then undertake to agree on the items in dispute no later than
180 days after the Closing. The version of such statement finally agreed to in
writing by Sellers and Purchaser shall constitute the "Final Closing Statement".
If the Final Closing Statement reflects a net positive amount in favor of
Purchaser, then within five days following the agreement of the parties as to
such Final Settlement Statement Sellers shall pay to Purchaser an amount equal
to such net positive amount. If the Final Closing Statement reflects a net
positive amount in favor of Sellers, then within five days following the
agreement of the parties as to such Final Settlement Statement Sellers shall be
entitled to receive from Purchaser, in addition to the Purchase Price, a payment
in an amount equal to such net positive amount. Any payment required to be made
pursuant to this Section 2.5 or pursuant to Section 2.2(g) that is not made when
due shall bear interest at a per annum rate equal to the lesser of (a) the
Interest Rate plus 10% and (b) 18%, from the date such payment was due until
paid. Any error in the Preliminary Closing Statement which was not observed
prior to the Closing shall be corrected on the Final Closing Statement.


                                   ARTICLE III
                                  TITLE MATTERS

         3.1 MARKETABLE TITLE; TITLE DEFECT. As used herein, the term
"Marketable Title" shall mean, as to each Property, such title as meets each of
the following requirements: (a) as to each Property that constitutes or includes
an Overriding Royalty Interest, (i) the Specified Percentage of the applicable
Seller with respect to the properties burdened by such Overriding Royalty
Interest is the percentage indicated on Exhibit C, (ii) the WI of the Assignor
with respect to the oil and gas leases and (if applicable) mineral fee interests
burdened by such Overriding Royalty Interest does not exceed the WI percentage
for such Property indicated on Exhibit C by more than 0.5%, (iii) the sum of (x)
the NRI of the Assignor with respect to the oil and gas leases and (if
applicable) mineral fee interests burdened by such Overriding Royalty Interests
and (y) if such Property includes one or more Royalty Interests, the aggregate
NRI of the applicable Seller with respect to such Royalty Interest(s), is not
more than 0.5% less than the NRI percentage for such Property indicated on
Exhibit C, (b) as to the Property described under item 15 and the Property
described under item 19 of Exhibit D, the NRI of Sellers with respect to such
Royalty Interest is not more than 0.5% less then the NRI percentage for such
Royalty Interest indicated on Exhibit C, and (c) the Overriding Royalty
Interests, Royalty Interests and Ancillary Rights relating to each Property are
not subject to any preferential purchase right or consent to assignment
applicable to the transactions contemplated hereby and are free and clear of
liens, claims and encumbrances, other than any liens for taxes and assessments
not yet delinquent, or if delinquent, that are being contested in good faith in
the ordinary course of business. There shall be deemed to exist a "Title Defect"
with respect to any Property listed in Exhibit C as to which Sellers do not have
Marketable Title. The bankruptcy or insolvency of any Assignor shall not
constitute a Title Defect, and as reflected in Section 2.2 the Case shall not
constitute a Title Defect. For purposes of this Section 3.1, as to each
Property, the term "NRI" refers to the sum of the NRI's of all Royalty Interests
included in such Property and the Assignor's NRI attributable to the properties
encumbered by the Overriding Royalty Interest included in such Property.

         3.2 NOTICE OF TITLE DEFECT. Purchaser shall notify Sellers of any Title
Defect as soon as reasonably practicable after Purchaser has knowledge thereof,
and in all events within 15 days after




                                       10

<PAGE>   18



the date hereof. Each such notice shall include Purchaser's proposed Defect
Value as to each Title Defect reflected therein. Any matters that would
otherwise constitute Title Defects but that are not specifically raised in
writing by Purchaser within such 15-day period shall conclusively be deemed
waived by Purchaser, but such waiver shall not affect any representations and
warranties set forth in Article IV.

         3.3 REMEDIES FOR TITLE DEFECT. Sellers shall have the right, but not
the obligation, to attempt to cure any Title Defect. With respect to any Title
Defect that Sellers elect not to cure or that Sellers fail to cure within 15
days after receiving notice of the Title Defect, the following shall be
applicable:

             (a)  If Sellers disagree with Purchaser's characterization of any
                  matter as a Title Defect, then the characterization of such
                  matter shall be submitted to Al Cummings, Houston, Texas, who
                  shall serve as the arbitrator (the "Arbitrator") who shall
                  determine whether each such matter so submitted constitutes a
                  Title Defect. The cost of the Arbitrator shall be borne
                  one-half by Sellers and one-half by Purchaser. Each party
                  shall present its position on the matter in question to the
                  Arbitrator within two business days after the Arbitrator is
                  requested to make a determination regarding the matter (each
                  party having the right to request such determination), and the
                  Arbitrator shall make a determination regarding the existence
                  of the alleged Title Defect and the extent of the property
                  interest affected by the alleged Title Defect as soon as
                  practicable thereafter (with an effort to have the
                  determination made within five business days after the
                  Arbitrator is requested to make the determination). The
                  determination by the Arbitrator shall be conclusive and
                  binding on the parties, and shall be enforceable against any
                  party in any court of competent jurisdiction.

             (b)  If Sellers do not agree as to the proposed Defect Value of a
                  particular Title Defect, then Ryder, Scott and Company
                  ("Consultant") shall determine the value from the Ryder Scott
                  Report, to the extent of the reserves therein determined
                  attributable to the lands covered by the particular proposed
                  Title Defect, and attributable to the particular property
                  interest in such lands which is subject to the particular
                  proposed Title Defect. The cost of the Consultant shall be
                  borne one-half by Sellers and one-half by Purchaser. Each
                  party shall present its position on the value in question to
                  the Consultant within two business days after the Consultant
                  is requested to determine the value (each party having the
                  right to request such determination), and the Consultant shall
                  make a determination of the value involved as soon as
                  practicable thereafter (with an effort to have the
                  determination made within five business days after the
                  Consultant is requested to determine the value). The
                  determination by the Consultant shall be conclusive and
                  binding on the parties, and shall be enforceable against any
                  party in any court of competent jurisdiction.

             (c)  If the aggregate Defect Value of all Title Defects is less
                  than $1,500,000, then the parties shall proceed to the closing
                  of the transaction contemplated





                                       11

<PAGE>   19



                  by this Agreement (subject to the conditions set forth
                  elsewhere in this Agreement) without any adjustment to the
                  Purchase Price.

             (d)  If the aggregate Defect Value of all Title Defects exceeds
                  $1,500,000, then Sellers and Purchaser shall seek to reach
                  mutual agreement on a reduction in the Purchase Price because
                  of such Title Defects, any such agreement to be satisfactory
                  to each party in its sole discretion and to be evidenced by a
                  written instrument executed by all of the parties. If no such
                  agreement is reached within three days after the date it is
                  determined that the aggregate Defect Value of all Title
                  Defects exceeds $1,500,000, each Property as to which one or
                  more of such Title Defects apply, together with all related
                  Ancillary Rights and Specified Agreements, shall be excluded
                  from the Assets to be transferred to Purchaser pursuant to
                  this Agreement, and the Purchase Price shall be reduced by the
                  allocated value set forth in Exhibit D with respect to each
                  such Property; provided, if in the aggregate the reduction in
                  the Purchase Price pursuant to this Section 3.3 should exceed
                  15.0% of the original Purchase Price, then Sellers, on the one
                  hand, or Purchaser, on the other hand, shall have the right,
                  by so notifying the other at least two days prior to the
                  Closing Date, to terminate this Agreement.


                                   ARTICLE IV

         12.1 APPORTIONMENT OF AD VALOREM AND PROPERTY TAXES. All ad valorem
taxes, real property taxes, personal property taxes and similar obligations with
respect to the Assets for the tax period in which the Effective Time occurs
shall be apportioned as of the Effective Time between Sellers and Purchaser. To
the extent any of such taxes attributable to the period prior to the Effective
Time by virtue of such apportionment have not been debited as an Expense to a
Net Cash Flow Account or otherwise paid by Sellers as of the Closing and
subsequent to the Closing Purchaser pays such taxes or such taxes are debited as
an Expense under a Net Cash Flow Account, Sellers shall pay to Purchaser
Sellers' portion of each such tax within 30 days after receipt of Purchaser's
invoice therefor indicating that such tax has been paid. To the extent any of
such taxes attributable to the period following the Effective Time by virtue of
such apportionment have not been debited as an Expense to a Net Cash Flow
Account but have otherwise been paid by Sellers as of the Closing, such taxes
shall be reflected on the Preliminary Closing Statement (to the extent of
available information) and on the Final Closing Statement.

         12.2 SALES TAXES. The Purchase Price provided for hereunder is net of
any sales taxes or other transfer taxes in connection with the sale of the
Assets. The parties believe that this sale is exempt from sales and transfer
taxes. Purchaser shall be liable for any applicable conveyance, transfer and
recording fees, and for real estate transfer stamps or taxes imposed on the
transfer of the Assets pursuant to this Agreement and, if a determination is
ever made that a sales tax or other transfer tax applies, for such sales tax or
transfer tax.

         12.3 PRODUCTION TAXES. All production, severance, excise, windfall
profit and other taxes relating to production of Minerals attributable to the
Assets prior to the Effective Time shall be borne by and for the account of
Sellers, and all such taxes relating to such production after the Effective Time
shall be borne by and for the account of Purchaser.

party with reasonable access to all relevant documents, data and other
information that may be required by the other party for the purpose of preparing
tax returns and responding to any audit by any taxing jurisdiction, including
the providing by Purchaser to Sellers after Closing with access to the Books and
Records, it being recognized that Sellers shall have the right at their expense

status as prior owners of the Assets. Each party to this Agreement shall
cooperate with all reasonable requests of the other party made in connection
with contesting the imposition of taxes.


                                  ARTICLE XIII
                    INDEPENDENT INVESTIGATION AND DISCLAIMER

         13.1 INDEPENDENT INVESTIGATION AND DISCLAIMER. Purchaser acknowledges
that (a) it has had and pursuant to this Agreement will have prior to the

has relied solely on the basis of its own independent investigation of the
Assets and such other matters and information deemed relevant by Purchaser, and
upon the representations, obligations, covenants and agreements in this
Agreement. Accordingly, Purchaser acknowledges that Sellers have not made, and
SELLERS HEREBY EXPRESSLY DISCLAIM AND NEGATE, ANY REPRESENTATION OR WARRANTY,
EXPRESSED, IMPLIED, AT COMMON LAW, BY STATUTE, OR OTHERWISE RELATING TO (i) THE
CONDITION OF THE ASSETS (INCLUDING WITHOUT LIMITATION, ANY IMPLIED OR EXPRESSED

         14.9 CONSEQUENTIAL DAMAGES. The parties waive any rights to incidental,
consequential, exemplary or punitive damages resulting from a breach of this
Agreement, including, without limitation, loss of profits.

         14.10 SURVIVAL. The representations, warranties, obligations, covenants
and agreements of the parties under this Agreement shall survive the Closing,
provided that any claim for a breach of representations and warranties set forth
in Articles IV and V must be brought within one year after the Closing Date, and
there shall be no remedy for any such claim not brought within such period.

         14.11 COUNTERPARTS. This Agreement may be executed in one or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         14.12 MUSTANG. Reference is made to the fact that the operator of the
Ramirez wells (wherein Mustang is the Assignor party) is asserting the right to
set-off against proceeds from the sale of production attributable to such wells
various amounts owed by Mustang. Morgan and Purchaser each agree that it shall
not enter into or consent to any settlement agreement or similar agreement
wherein such operator is given the right to set-off against proceeds of
post-Effective Time production attributable to such wells any of such amounts
owed by Mustang that were incurred by such operator prior to the Effective Time.
Notwithstanding the foregoing, if the operator of the Ramirez wells files an
action to foreclosure any lien it has on the Assignor's interest in such wells,
then (i) upon becoming aware thereof each party shall give notice thereof to the
other, (ii) to the extent either party desires to negotiate a settlement with
the operator to avoid such foreclosure, the party shall have the right to
participate in such negotiations, and (iii) if by the fifth day preceding the
foreclosure date Morgan has not reached a settlement, then Queen Sand shall have
the right to enter into a settlement with the operator (without Morgan's
consent) and if such settlement is so entered Morgan shall reimburse Queen Sand
for the amount paid in such settlement up to $980,000 less any amounts
previously paid to Queen Sand pursuant to Section 2.3(b) within ten days
following written demand by Queen Sand.

         14.13 TRUSTEE LIABILITY. Notwithstanding anything express or implied to
the contrary, none of Morgan Guaranty Trust Company of New York ("Morgan") or
any of its affiliates (including, without limitation J.P. Morgan Investment
Management, Inc.), any directors, officers, employees or agents of Morgan or any
such affiliate, and any directors, officers, employees or agents of Seller III
or Seller IV shall have any personal or corporate liability under or in any
manner resulting from this Agreement; rather, Purchaser agrees that any claim or
cause of action that Purchaser may have or assert against a Seller and prevail
on shall be satisfied solely from the assets of the trusts that constitute
Seller I and Seller II and the assets of Seller III and Seller IV, as
applicable. Purchaser acknowledges that Morgan is acting hereunder in its
trustee capacity only and that J. P. Morgan Investment Management, Inc. has
acted only as an advisor to Morgan.

    Morgan believes that Mustang may not have paid the operator for all or a
    substantial part of the operations covered by the invoices, and if so then
    the corresponding amounts under these invoices are invalid. In addition,
    Morgan has not and will not pay such amounts; rather, Morgan has and will
    set-off such amounts against the payments of Net Cash Flow due to Morgan for
    periods prior to the Effective Time but which have not been paid by Mustang.

2.  Morgan has sent to Mustang and Gulf notices that Mustang has failed to:

    a.   Pay to Morgan amounts due pursuant to the terms of the Conveyance of
         Overriding Royalty Interest to which Mustang is a party.

    b.   Properly establish and cause proceeds of production to be deposited in
         the segregated account required to be established pursuant to the terms
         of such Conveyance of Overriding Royalty Interest.

    c.   Pay lease operating expenses, drilling expenses and other costs and
         expenses associated with the properties burdened by the Overriding
         Royalty Interest granted to Morgan by Mustang.

3.  Morgan has sent to WRT Energy Corporation notice that WRT has failed to
    provide accounting information and make payments, if any, pursuant to
    the terms of its Conveyance for the accounting months of November and
    December, 1997 and January 1998.

                                ESCROW AGREEMENT


         THIS ESCROW AGREEMENT (as the same may be amended or modified from time
to time and including any and all written instructions given to "Escrow Agent"
(hereinafter defined) pursuant hereto, this "Escrow Agreement") is made and
entered into as of             , 1998 by and among MORGAN GUARANTY TRUST COMPANY
OF NEW YORK, a Trustee under Declaration of Trust dated November 10, 1982, as
amended, for the Commingled Pension Trust Fund (Petroleum II) ("Party A"), QUEEN
SAND RESOURCES, INC., a Nevada corporation ("Party B", and together with Party
A, sometimes referred to collectively as the "Other Parties"), and CHASE BANK OF
TEXAS, NATIONAL ASSOCIATION, a national banking association with its principal
offices in Houston, Harris County, Texas (the "Bank").

                              W I T N E S S E T H :

         Party A, Party B and certain other entities are parties to a Purchase
and Sale Agreement dated March 19, 1998 (the "Purchase Agreement"). The closing
of the transaction contemplated by the Purchase Agreement is occurring on or
about the date hereof and in connection with such closing $8,000,000 of the
purchase price consideration to be paid under the Purchase Agreement, together
with a reconveyance, is required to be placed in escrow pursuant to this Escrow
Agreement.

         WHEREAS, Party A and Party B have requested Bank to act in the capacity
of escrow agent under this Escrow Agreement, and Bank, subject to the terms and
conditions hereof, has agreed so to do.

         NOW, THEREFORE, in consideration of the premises and mutual covenants
and agreements contained herein, the parties hereto hereby agree as follows:

         1. Appointment of Escrow Agent. Each of Party A and Party B hereby
appoints the Bank as the escrow agent under this Escrow Agreement (the Bank in
such capacity, the "Escrow Agent"), and Escrow Agent hereby accepts such
appointment.

         2. Deposit; Documents. (a) Upon execution of this Escrow Agreement,
Party B will deliver to the Escrow Agent the sum of U.S. Eight Million and
No/100 Dollars ($8,000,000) (as said amount may increase or decrease as a result
of the investment and reinvestment thereof and as said amount may be reduced by
charges thereto and payments and setoffs therefrom to compensate or reimburse
Escrow Agent for amounts owing to it pursuant hereto, the "Deposit") to be held
by Escrow Agent in accordance with the terms hereof. Subject to and in
accordance with the terms and conditions hereof, Escrow Agent agrees that it
shall receive, hold in escrow, invest and reinvest and release or distribute the
Deposit. It is hereby expressly stipulated and agreed that all interest and
other earnings on the Deposit shall become a part of the Deposit for all
purposes, and that all losses resulting from the investment or reinvestment
thereof from time to time and all amounts charged thereto to compensate or
reimburse the Escrow Agent from time to time for amounts owing to it hereunder
shall from the time of such loss or charge no longer constitute part of the
Deposit. For purposes of any applicable income tax laws and for all other
purposes of this Escrow Agreement,


                                        1

<PAGE>   87



the Deposit and all income thereon shall constitute the property of Party A, but
shall only be disbursed in accordance with the terms of this Agreement.

            (b) Upon execution of this Escrow Agreement, Party B will execute,
acknowledge and deliver to Escrow Agent a Reconveyance and Assignment of Royalty
Interests in a form previously approved by Party A and Party B (the
"Assignment"), and Party A, Party B and Bank will execute, acknowledge and
deliver to each other original counterparts of a Memorandum of Reconveyance and
Assignment, which memorandum will be placed of record in Real Property Records
of Zapata County, Texas by Party A. The Assignment shall be held in escrow by
Escrow Agent in accordance with the terms of this Agreement.

         3. Investment of the Deposit. Escrow Agent shall invest and reinvest
the Deposit in the Vista Treasury Plus Money Market Fund, unless otherwise
instructed jointly in writing by Party A and Party B. Such written instructions,
if any, referred to in the foregoing sentence shall specify the type and
identity of the investments to be purchased and/or sold and shall also include
the name of the broker-dealer, if any, which Party A and Party B direct the
Escrow Agent to use in respect of such investment, any particular settlement
procedures required, if any (which settlement procedures shall be consistent
with industry standards and practices), and such other information as Escrow
Agent may require. Escrow Agent shall not be liable for failure to invest or
reinvest funds absent sufficient written direction. Unless Escrow Agent is
otherwise directed in such written instructions, Escrow Agent may use a
broker-dealer of its own selection, including a broker-dealer owned by or
affiliated with Escrow Agent or any of its affiliates. It is expressly agreed
and understood by the parties hereto that Escrow Agent shall not in any way
whatsoever be liable for losses on any investments, including, but not limited
to, losses from market risks due to premature liquidation or resulting from
other actions taken pursuant to this Escrow Agreement.

         Receipt, investment and reinvestment of the Deposit shall be confirmed
by Escrow Agent as soon as practicable by account statement, and any
discrepancies in any such account statement shall be noted by Party A or Party B
to Escrow Agent within 30 calendar days after receipt thereof. Failure to inform
Escrow Agent in writing of any discrepancies in any such account statement
within said 30-day period shall conclusively be deemed confirmation of such
account statement in its entirety. For purposes of this paragraph, (a) each
account statement shall be deemed to have been received by the party to whom
directed on the earlier to occur of (i) actual receipt thereof and (ii) three
"Business Days" (hereinafter defined) after the deposit thereof in the United
States Mail, postage prepaid and (b) the term "Business Day" shall mean any day
of the year, excluding Saturday, Sunday and any other day on which national
banks are required or authorized to close in Houston, Texas.

         4. Disbursement of Deposit; Delivery of Assignment. Escrow Agent is
hereby authorized to make disbursements of the Deposit and to deliver the
Assignment only as follows:

            (a) Upon receipt of written instructions signed by either Party A or
Party B (which instructions shall have attached thereto a certified copy of the
unappealable judgment or order of dismissal as against Seller II as a defendant
in the case styled "Lannie Mecom f/k/a/ Lannie Mecom Moses v. Vinson & Elkins,
et al," Cause No. 96-25436, formerly in the 80th Judicial District Court of
Harris County (and now on appeal)) and otherwise in form and substance
satisfactory to Escrow Agent, in accordance with such instructions; provided, at
least five business days prior to undertaking any performance pursuant to said
written instructions, the Escrow Agent shall deliver

                                        2

<PAGE>   88



notice to the other party (being either Party A or Party B, who did not deliver
the written instructions) of the written instructions so received by the Escrow
Agent.

            (b) As to the Deposit, as permitted by this Escrow Agreement to
Escrow Agent; and

            (c) Into the registry of the court in accordance with Sections 8 or
15 hereof.

Notwithstanding anything contained herein or elsewhere to the contrary, the
Other Parties hereby expressly agree that the Escrow Agent shall be entitled to
charge the Deposit for, and pay and setoff from the Deposit, any and all
amounts, if any, then owing to it pursuant to this Escrow Agreement prior to the
disbursement of the Deposit in accordance with clauses (a) through (c) (both
inclusive) of this Section 4.

         5. Tax Matters. Party A shall provide Escrow Agent with its taxpayer
identification number documented by an appropriate Form W 8 or Form W 9 upon
execution of this Escrow Agreement. Failure so to provide such forms may prevent
or delay disbursements from the Deposit and may also result in the assessment of
a penalty and Escrow Agent's being required to withhold tax on any interest or
other income earned on the Deposit. Any payments of income shall be subject to
applicable withholding regulations then in force in the United States or any
other jurisdiction, as applicable.

         6. Scope of Undertaking. Escrow Agent's duties and responsibilities in
connection with this Escrow Agreement shall be purely ministerial and shall be
limited to those expressly set forth in this Escrow Agreement. Escrow Agent is
not a principal, participant or beneficiary in any transaction underlying this
Escrow Agreement and shall have no duty to inquire beyond the terms and
provisions hereof. Escrow Agent shall have no responsibility or obligation of
any kind in connection with this Escrow Agreement or the Deposit and shall not
be required to deliver the Deposit or any part thereof or take any action with
respect to any matters that might arise in connection therewith, other than to
receive, hold, invest, reinvest and deliver the Deposit as herein provided.
Without limiting the generality of the foregoing, it is hereby expressly agreed
and stipulated by the parties hereto that Escrow Agent shall not be required to
exercise any discretion hereunder and shall have no investment or management
responsibility and, accordingly, shall have no duty to, or liability for its
failure to, provide investment recommendations or investment advice to the Other
Parties or either of them. Escrow Agent shall not be liable for any error in
judgment, any act or omission, any mistake of law or fact, or for anything it
may do or refrain from doing in connection herewith, except for, subject to
Section 7 hereinbelow, its own willful misconduct or gross negligence. It is the
intention of the parties hereto that Escrow Agent shall never be required to
use, advance or risk its own funds or otherwise incur financial liability in the
performance of any of its duties or the exercise of any of its rights and powers
hereunder.

         7. Reliance; Liability. Escrow Agent may rely on, and shall not be
liable for acting or refraining from acting in accordance with, any written
notice, instruction or request or other paper furnished to it hereunder or
pursuant hereto and believed by it to have been signed or presented by the
proper party or parties. Escrow Agent shall be responsible for holding,
investing, reinvesting and disbursing the Deposit pursuant to this Escrow
Agreement; provided, however, that in no event shall Escrow Agent be liable for
any lost profits, lost savings or other special, exemplary, consequential or
incidental damages in excess of Escrow Agent's fee hereunder and provided,

                                        3

<PAGE>   89



further, that Escrow Agent shall have no liability for any loss arising from any
cause beyond its control, including, but not limited to, the following: (a) acts
of God, force majeure, including, without limitation, war (whether or not
declared or existing), revolution, insurrection, riot, civil commotion,
accident, fire, explosion, stoppage of labor, strikes and other differences with
employees; (b) the act, failure or neglect of any Other Party or any agent or
correspondent or any other person selected by Escrow Agent; (c) any delay,
error, omission or default of any mail, courier, telegraph, cable or wireless
agency or operator; or (d) the acts or edicts of any government or governmental
agency or other group or entity exercising governmental powers. Escrow Agent is
not responsible or liable in any manner whatsoever for the sufficiency,
correctness, genuineness or validity of the subject matter of this Escrow
Agreement or any part hereof or for the transaction or transactions requiring or
underlying the execution of this Escrow Agreement, the form or execution hereof
or for the identity or authority of any person executing this Escrow Agreement
or any part hereof or depositing the Deposit.

         8. Right of Interpleader. Should any controversy arise involving the
parties hereto or any of them or any other person, firm or entity with respect
to this Escrow Agreement or the Deposit, or should a substitute escrow agent
fail to be designated as provided in Section 15 hereof, or if Escrow Agent
should be in doubt as to what action to take, Escrow Agent shall have the right,
but not the obligation, either to (a) withhold delivery of the Deposit until the
controversy is resolved, the conflicting demands are withdrawn or its doubt is
resolved or (b) institute a petition for interpleader in any court of competent
jurisdiction to determine the rights of the parties hereto. In the event Escrow
Agent is a party to any dispute, Escrow Agent shall have the additional right to
refer such controversy to binding arbitration. Should a petition for
interpleader be instituted, or should Escrow Agent be threatened with litigation
or become involved in litigation or binding arbitration in any manner whatsoever
in connection with this Escrow Agreement or the Deposit, the Other Parties
hereby jointly and severally agree to reimburse Escrow Agent for its attorneys'
fees and any and all other expenses, losses, costs and damages incurred by
Escrow Agent in connection with or resulting from such threatened or actual
litigation or arbitration prior to any disbursement hereunder.

         9. Indemnification. The Other Parties hereby jointly and severally
indemnify Escrow Agent, its officers, directors, partners, employees and agents
(each herein called an "Indemnified Party") against, and hold each Indemnified
Party harmless from, any and all expenses, including, without limitation,
attorneys' fees and court costs, losses, costs, damages and claims, including,
but not limited to, costs of investigation, litigation and arbitration, tax
liability and loss on investments suffered or incurred by any Indemnified Party
in connection with or arising from or out of this Escrow Agreement, except such
acts or omissions as may result from the willful misconduct or gross negligence
of such Indemnified Party. IT IS THE EXPRESS INTENT OF EACH OF PARTY A AND PARTY
B TO INDEMNIFY EACH OF THE INDEMNIFIED PARTIES FOR, AND HOLD THEM HARMLESS
AGAINST, THEIR OWN NEGLIGENT ACTS OR OMISSIONS.

         10. Compensation and Reimbursement of Expenses. Party A and Party B
each hereby agrees to pay Escrow Agent for its services hereunder in accordance
with Escrow Agent's fee schedule as in effect from time to time and to pay all
expenses incurred by Escrow Agent in connection with the performance of its
duties and enforcement of its rights hereunder and otherwise in connection with
the preparation, operation, administration and enforcement of this Escrow
Agreement, including, without limitation, attorneys' fees, brokerage costs and
related expenses incurred by Escrow Agent. As between Party A and Party B, such
fees and expenses shall be borne

                                        4

<PAGE>   90



one-half by Party A and one-half by Party B. The foregoing notwithstanding, the
Other Parties shall be jointly and severally liable to Escrow Agent for the
payment of all such fees and expenses. In the event the Other Parties for any
reason fail to pay any such fees and expenses as and when the same are due, such
unpaid fees and expenses shall be charged to and set-off and paid from the
Deposit by Escrow Agent without any further notice.

         11. Lien. Each of the Other Parties hereby grants to Escrow Agent a
lien upon, and security interest in, all its right, title and interest in and to
all of the Deposit as security for the payment and performance of its
obligations owing to Escrow Agent hereunder, including, without limitation, its
obligations of payment, indemnity and reimbursement provided for hereunder,
which lien and security interest may be enforced by Escrow Agent without notice
by charging and setting off and paying from, the Deposit any and all amounts
then owing to it pursuant to this Escrow Agreement or by appropriate foreclosure
proceedings.

         12. Notices. Any notice or other communication required or permitted to
be given under this Escrow Agreement by any party hereto to any other party
hereto shall be considered as properly given if in writing and (a) delivered
