Dear Shareholder:

     Attached to this letter is a supplement to our Proxy Statement dated
December 27, 2000 relating to a special meeting of shareholders of Universal
Compression Holdings, Inc., which updates our proposed financing transactions in
connection with our pending acquisition of Weatherford Global Compression
Services, L.P. and certain related entities (WGC). The supplement also includes
revised unaudited pro forma combined condensed financial information to
illustrate the effect of the proposed WGC acquisition and related financing
transactions.

     OUR BOARD OF DIRECTORS BELIEVES THAT THE ISSUANCE OF 13,750,000 SHARES OF
OUR COMMON STOCK IN CONNECTION WITH THE WGC ACQUISITION AND THE AMENDMENT TO OUR
INCENTIVE STOCK OPTION PLAN TO INCREASE THE NUMBER OF SHARES OF OUR COMMON STOCK
AUTHORIZED FOR ISSUANCE UNDER THE PLAN FROM 1,912,421 SHARES TO 3,012,421 SHARES
ARE FAIR TO AND IN THE BEST INTERESTS OF OUR SHAREHOLDERS AND RECOMMENDS THAT
YOU VOTE FOR THESE PROPOSALS.

     In order to give you an opportunity to evaluate the attached supplement, we
will not submit the proposed issuance of our common stock in the acquisition and
the amendment to our Incentive Stock Option Plan to a vote when the special
meeting is convened on February 6, 2001. Instead, the only action that will be
taken at such meeting will be to adjourn the meeting until Friday, February 9,
2001, on which date the special meeting will reconvene at 9:00 a.m., local time,
at the Drury Inn, 100 Highway 6, Houston, Texas 77079.

broker, your shares will not be voted on the proposals and will have no effect
on the result of the vote, provided that holders of at least a majority of the
shares entitled to vote at the special meeting cast votes.

     Our Board of Directors does not presently intend to bring any business
before the special meeting other than that referred to in the proxy statement,
as modified by this supplement.

RECENT DEVELOPMENTS

     We have been negotiating the financing transactions that are necessary to
consummate our acquisition of Weatherford Global Compression Services, L.P. and
certain related entities ("WGC"). We intend to raise at least $427 million under
a new operating lease facility to be funded primarily through an offering of
approximately $350 million in senior secured notes by an unaffiliated entity. We
also intend to enter into a new secured revolving credit facility of up to $125
million and a new asset-backed securitization operating lease facility of up to
$200 million (the "ABS Operating Lease Facility"). We initially expect to fund
approximately $75 million under the ABS Operating Lease Facility and expect to
have no amounts initially outstanding under the new revolving credit facility.
The proceeds from the two new operating lease facilities will be used to
refinance certain existing indebtedness and restructure existing operating lease
obligations of Universal and WGC.

     On January 2, 2001, Universal Compression, Inc., a Texas corporation and
wholly owned subsidiary of Universal Compression Holdings, Inc. ("UCI"),
commenced an offer to purchase all of its existing 9 7/8% Senior Discount Notes
due 2008. UCI also solicited the consent of the holders of the 9 7/8% Senior
Discount Notes to amend the indenture governing the notes to eliminate
substantially all the restrictive covenants.

     On January 26, 2001, UCI announced that it had terminated its offer to
purchase its 9 7/8% Senior Discount Notes. The related consent solicitation
expired at 5:00 p.m., New York City time, on January 24, 2001. Our pending
acquisition of WGC and related financing transactions are not conditioned upon
the completion of the tender offer and consent solicitation. The requisite
consents from the holders of the 9 7/8% notes for the proposed amendment to the
indenture governing the notes were not received prior to the extended deadline.

     The existing 9 7/8% notes will remain outstanding and, upon consummation of
the pending WGC acquisition, will be subject to the right of the holders to
require Universal to repurchase the notes at 101% of the accreted value, plus
accrued and unpaid interest, if any, pursuant to the terms of the indenture. To
the extent holders exercise such right, we intend to fund such repurchase of the
9 7/8% notes under our new revolving credit facility or the ABS Operating Lease
Facility. As a result of the termination of the tender offer and expiration of
the consent solicitation, we adjusted the amount we initially expected to fund
under the ABS Operating Lease Facility.

     In connection with the proposed financing transactions, we have updated our
unaudited pro forma financial information contained in the proxy statement. The
section entitled "Selected Unaudited Pro Forma Combined Condensed Financial
Information of Universal Compression Holdings, Inc." on page 17 of the proxy
statement is revised to give effect to the events recited above under "Recent
Developments" by replacing in its entirety the table set forth on page 17 of the
proxy statement with the following:

           SELECTED UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL
              INFORMATION OF UNIVERSAL COMPRESSION HOLDINGS, INC.

     The pro forma financial data set forth in the table below has been derived
from the Unaudited Pro Forma Combined Condensed Financial Statements and the
notes thereto which are included in this proxy statement, as modified by this
supplement. You should read those statements for a further description of the
financial data summarized here. The selected unaudited pro forma statements of
operations data for the six months ended September 30, 2000 and the year ended
March 31, 2000 give effect to UCH's initial public offering, the WGC acquisition
and related financing transactions as if the transactions had occurred on April
1, 2000 for purposes of the six months ended September 30, 2000 and on April 1,
1999 for the year ended March 31, 2000. The unaudited pro forma balance sheet as
of September 30, 2000 gives effect to UCH's initial public offering, the WGC
acquisition and the related financing transactions as if the transactions had
occurred on September 30, 2000. Because the fiscal years of Universal and WGC
differ, WGC's historical operating results for the year ended March 31, 2000
include its first quarter results of 2000, combined with its results for the
nine months ended December 31, 1999. The pro forma financial data shown in the
table below are not necessarily indicative of what our results of operations or
financial position would have been had the WGC acquisition been completed as of
the date reflected or that may be achieved in the future. Please see "Unaudited
Pro Forma Combined Condensed Financial Information" in this supplement for a
description of the pro forma adjustments to the historical financial statements
of Universal and WGC showing the effect of the WGC acquisition and the related
financing transactions. You should also read the historical financial statements
and accompanying disclosures contained in the proxy statement. You should also
read Universal's Annual Report on Form 10-K for the fiscal year ended March 31,
2000, as amended, Universal's Quarterly Report on Form 10-Q for the quarter
ended September 30, 2000 and Universal's Current Reports on Form 8-K filed since
such date.

     The section entitled "Risk Factors" commencing on page 18 of the proxy
statement is amended to give effect to the events recited above under "Recent
Developments" in this supplement by adding the following risk factor:

TO THE EXTENT THAT HOLDERS OF UCI'S 9 7/8% SENIOR DISCOUNT NOTES REQUIRE UCI TO
REPURCHASE THE NOTES FOLLOWING THE ACQUISITION OF WGC, WE MUST FINANCE SUCH
REPURCHASE.

     The completion of the WGC acquisition will result in a change of control of
UCI under the indenture for the 9 7/8% Senior Discount Notes. As such, each
holder of the 9 7/8% Senior Discount Notes will have the right to require UCI to
repurchase such holder's 9 7/8% Senior Discount Notes at a price equal to 101%
of their accreted value, plus accrued and unpaid interest, if any, to the date
of repurchase. To the extent that holders of UCI's 9 7/8% Senior Discount Notes
require UCI to repurchase the notes, we currently intend to finance any such
repurchase through the use of commitments under our proposed new revolving
credit facility or our proposed ABS Operating Lease Facility. There can,
however, be no assurance as to the terms and conditions that will be available
to us for any such financing.

     The section entitled "Unaudited Pro Forma Combined Condensed Financial
Information" commencing on page 43 is revised to give effect to the events
recited above under "Recent Developments" in this supplement by replacing in
their entirety the data and tables beginning on page 43 and ending on page 50 of
the proxy statement with the following:

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL INFORMATION

     The following unaudited pro forma combined condensed financial statements
are based on the historical consolidated financial statements and the notes
thereto of Universal and WGC (or "Enterra" in reference to the parent company of
WGC) and have been prepared to illustrate the effect of the WGC acquisition and
the related financing transactions. The unaudited pro forma combined condensed
financial statements should be read in conjunction with the historical financial
statements and accompanying disclosures contained in the proxy statement. You
should also read Universal's Annual Report on Form 10-K for the fiscal year
ended March 31, 2000, as amended, its Quarterly Report on Form 10-Q for the
quarter ended September 30, 2000 and its Current Reports on Form 8-K filed since
such date.

     The unaudited pro forma combined condensed balance sheet as of September
30, 2000 and the unaudited pro forma combined condensed statements of operations
for the six months ended September 30, 2000 and the fiscal year ended March 31,
2000 have been prepared to give effect to the transactions set forth below as if
those transactions had occurred at the balance sheet date and at the beginning
of the income statement periods. Because the fiscal years of Universal and WGC
differ, WGC's historical operating results for the fiscal year ended March 31,
2000 include its first quarter results of 2000, combined with its results for
the nine months ended December 31, 1999.

     The unaudited pro forma combined condensed financial statements presented
herewith give effect to:

     - the initial public offering of UCH's common stock and concurrent debt
       restructuring and operating lease facility, which occurred in May 2000,
       as well as UCH's common stock split and conversion of UCH's preferred
       stock and non-voting common stock that occurred concurrently with our
       initial public offering;

     - the transfer of GSI and related assets to Weatherford entities other than
       Enterra and its subsidiaries prior to the WGC acquisition as described
       more fully in "The Merger Agreement -- Certain Pre-Closing Transfers"
       (page 65 of the proxy statement); and

     - completion of the WGC acquisition and the related financing transactions.

     We have not included in the unaudited pro forma combined condensed
financial statements the annual cost savings and other synergies of an estimated
$20 million that Universal's management expects to realize by the end of fiscal
2002 as a result of the WGC acquisition. While Universal believes these savings
and synergies will occur, we cannot assure you they will be realized either as
quickly or as fully expected, if at all. The unaudited pro forma combined
condensed financial statements also do not give effect to our acquisition of Gas
Compression Services, Inc. ("GCSI") on September 15, 2000. The unaudited pro
forma condensed combined financial statements presented below do not reflect
future events that may occur after the WGC acquisition.

     At this time, Universal's management is finalizing negotiations with
several financial institutions to determine the appropriate debt structure of
the combined company. For purposes of the accompanying unaudited pro forma
combined condensed financial information the assumptions are (a) a new $427
million operating lease facility with an unaffiliated entity primarily funded
through an offering of approximately $350 million of senior secured notes by
such entity, (b) a new $125 million secured revolving credit facility and (c) a
new $200 million asset-backed securitization operating lease facility. We have
assumed that none of the current holders of our 9 7/8% Senior Discount Notes
will exercise their right to require Universal to repurchase the outstanding
bonds at 101% of the accreted value, plus accrued and unpaid interest, if any,
pursuant to the terms of the indenture following consummation of the WGC
acquisition. At this time, we cannot determine the final terms of the new
indebtedness and operating lease
                                        5
   8

arrangements, or the final amount of our existing senior notes, if any, that the
holders of such notes may require us to repurchase, which amount could vary
significantly.

     We have accounted for the WGC acquisition using the purchase method of
accounting. WGC's property, plant and equipment balances have been adjusted to
their estimated fair values. In addition, WGC's reported current assets and
current liabilities are assumed to be their estimated fair values included in
the unaudited pro forma combined condensed financial statements. The final
allocation of the purchase price of the merger will differ from the amounts
represented in the unaudited pro forma combined condensed financial statements.

     The accompanying unaudited pro forma combined condensed financial
statements should be read in conjunction with the historical consolidated
financial statements of Universal and WGC and the notes thereto, which are
included in the proxy statement. The unaudited pro forma combined condensed
financial statements are provided for informational purposes only and do not
purport to represent what our financial position or results of operations would
actually have been had the WGC acquisition occurred on such dates or to project
our results of operations or financial position for any future period.

     References to "Enterra" in the pro forma combined condensed financial
statements mean WGC as defined in the "Recent Developments" section of, and used
elsewhere in, this proxy statement, as modified by this supplement.

                NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED
                              FINANCIAL STATEMENTS

 (1) Reflects Enterra's historical balances adjusted to exclude its
     Singapore-based operations (other than Australia and Thailand) and $10
     million of accounts receivable, which are not included in the WGC
     acquisition.

 (2) Reflects (a) the preliminary revaluation of Enterra's property, plant and
     equipment historical balances to estimated fair value ($63.2 million) and
     (b) the estimated initial sale and leaseback of additional compression
     equipment ($104.2 million) pursuant to the proposed new operating lease
     facilities assumed to be consummated concurrently with the WGC acquisition.

 (3) Represents the elimination of Enterra Adjusted Actual goodwill ($224.7
     million) offset by Universal's preliminary estimate of the excess of the
     total purchase price over the allocated fair value of the net assets of
     Enterra ($90.5 million). The purchase price includes advisory fees but not
     all acquisition related costs. The final allocation of the purchase price
     in the WGC acquisition will differ from the amounts represented in the
     unaudited pro forma combined condensed financial statements.

 (4) Represents adjustment for (a) the elimination of prepaid financing costs
     associated with UCI's operating lease facility and revolving credit
     facility ($4.9 million), which, for purposes of these pro forma
     adjustments, are assumed to be entirely refinanced concurrently with the
     WGC acquisition and (b) the recording of prepaid finance costs associated
     with the proposed operating lease facilities and revolving credit facility
     ($16.7 million).

 (5) Represents the retirement of WGC's debt using proceeds from the proposed
     new operating lease facilities ($16.1 million).

 (6) Represents the estimated deferred income taxes related to expense items
     associated with the elimination of prepaid financing costs associated with
     UCI's operating lease facility and revolving credit facility.

 (7) Reflects the elimination of Enterra's minority interest liability as a
     result of the purchase of GE Capital's interest by Enterra concurrently
     with the WGC acquisition.

 (8) Reflects the forgiveness of Enterra's payable to Weatherford concurrently
     with the WGC acquisition.

 (9) Represents the elimination of the deferred gain associated with the
     retirement of the existing operating lease facilities of WGC ($92.9
     million). Also reflects the estimated additional deferred gain ($32.6
     million) associated with the sale of compression equipment pursuant to the
     proposed new operating lease facilities. Additional deferred gain is
     assumed to equal approximately 30% of the proceeds from the sale of
     compression equipment pursuant to such new operating lease facilities.

(10) Reflects the elimination of Enterra's stockholders' equity ($216.3 million)
     and the valuation of UCH's common stock issued to an affiliate of
     Weatherford in the WGC acquisition ($392.7 million). Valuation assumes
     13,750,000 shares of UCH common stock valued at $28.56 per share, which is
     the five-day average closing price surrounding October 24, 2000, the
     announcement date of the WGC acquisition. Also reflects the write-off of
     prepaid finance costs ($3.1 million, net of taxes) associated with the
     proposed restructuring of the existing operating lease facility and
     revolving credit facility.

(11) Reflects the elimination of depreciation expense associated with the sale
     of compression equipment pursuant to the existing operating lease facility,
     with initial funding under the existing operating lease of $62.6 million.

(12) Reflects the expenses associated with the existing operating lease
     facility, including the related commitment fee.

                                       10

(13) Reflects the adjustment of interest expense related to the redemption of
     certain indebtedness at the beginning of the period and incremental
     borrowing during the period with the proceeds of UCH's initial public
     offering and its existing operating lease facility. Also includes the
     commitment fees associated with the new revolving credit facility.

(14) Represents the non-recurring charges related to the elimination of a
     management agreement and a consulting agreement and other related fees in
     connection with UCH's initial public offering and concurrent financing
     transactions in May 2000.

(15) An estimated statutory tax rate of 37.5% is assumed for pro forma
     adjustments. The effective tax rate may differ.

(16) Reflects (a) an estimated adjustment to goodwill amortization resulting
     from the change in the goodwill balance resulting from the preliminary
     allocation of the purchase price in the WGC acquisition ($1.7 million), (b)
     the estimated reduction of depreciation expense resulting from the
     preliminary revaluation of the purchase price to rental equipment acquired
     in the WGC acquisition and the estimated additional sale of compression
     equipment pursuant to the proposed new operating lease facilities ($5.7
     million), with an aggregate assumed funding under the proposed operating
     leases of $478.4 million by the end of the period, which funding includes
     the transfer of equipment from the existing operating lease facilities and
     the sale and leaseback of additional equipment under the new facilities and
     (c) the reduction of depreciation expense resulting from the preliminary
     revaluation of the purchase price to non-compression equipment acquired in
     the WGC acquisition ($3.4 million). Depreciation and amortization is
     calculated using an estimated useful life of 15 years with a 20% salvage
     value for rental equipment and an estimated useful life of seven years for
     non-compression equipment, while goodwill is amortized over 40 years.

(17) Reflects the net rental payments associated with the proposed new operating
     lease facilities ($20.7 million) and amortization of the lease structuring
     and arrangement fees ($1.1 million) estimated to be approximately $15.0
     million on the closing of the facilities. Also reflects the elimination of
     the existing facilities ($14.5 million), including the expected related
     commitment fee, with assumed funding under the new facilities of $478.4
     million by the end of the period, which facilities are currently being
     negotiated. The proposed operating lease facilities will replace
     Universal's and WGC's existing facilities. The rental payments under the
     lease facilities are assumed to include an amount based on LIBOR plus a
     variable amount depending on UCI's operating and financial results, applied
     to the funded amount of the leases. The operating lease calculations assume
     an interest rate of 9.16% and a seven-year lease term. A fluctuation of
     .125% of actual rates related to the proposed new operating lease
     facilities would result in an approximate change of $523,000 in rental
     payments on an annual basis.

(18) Reflects the adjustment of interest expense related to the retirement of
     WGC's indebtedness at the beginning of the period.

(19) Represents interest income generated on an average excess cash balance of
     $56.2 million invested at a rate equivalent to Universal's proposed new
     senior secured notes operating lease facility. The effect of a .25% change
     in interest rates on income (loss) before extraordinary items would be
     $44,000.

(20) Reflects the elimination of Enterra's minority interest expense as a result
     of the purchase of GE Capital's interest by Enterra concurrently with the
     WGC acquisition.

(21) Includes the effect of the 7,275,000 shares of common stock offered in, and
     the outstanding stock split and conversion that occurred concurrently with,
     UCH's initial public offering and the 13,750,000 shares of UCH's common
     stock to be issued to an affiliate of Weatherford in the WGC acquisition as
     if these transactions had occurred at April 1, 2000. Also includes the
     weighted average effect of the 1,400,726 shares of UCH's common stock
     issued as partial consideration for the GCSI acquisition that occurred on
     September 15, 2000. Excludes options to purchase up to 318,000 shares of
     UCH's common stock that we are obligated to issue to certain WGC employees
     in connection with the WGC acquisition.
                                       11

(22) Represents elimination of Castle Harlan management fees ($3.0 million) and
     Mr. Urcis' consulting fees ($0.2 million) which were terminated at the time
     of UCH's initial public offering and related debt restructuring.

(23) Reflects the elimination of depreciation expense associated with the sale
     of compression equipment pursuant to the existing operating lease facility,
     with initial funding under such facility of $61.3 million.

(24) Reflects the adjustment of interest expense related to the redemption of
     certain indebtedness at the beginning of the period totaling $177.8 million
     and $12.8 million of incremental borrowing during the period from the
     proceeds of UCH's initial public offering and its existing operating lease
     facility. Also includes the commitment fees associated with Universal's
     existing revolving credit facility.

(25) Reflects (a) an estimated adjustment to goodwill amortization resulting
     from the change in the goodwill balance resulting from the preliminary
     allocation of the purchase price in the WGC acquisition ($3.2 million), (b)
     the estimated reduction of depreciation expense resulting from the
     preliminary revaluation of the purchase price to rental equipment acquired
     in the WGC acquisition and the estimated additional sale of compression
     equipment pursuant to the proposed new operating lease facilities ($7.4
     million), with an aggregate assumed funding under such facilities of $478.4
     million by the end of the period, which funding includes the transfer of
     equipment from the existing operating lease facilities and the sale and
     leaseback of additional equipment under the new facilities and (c) the
     reduction of depreciation expense resulting from the preliminary
     revaluation of the purchase price to non-compression equipment acquired in
     the WGC acquisition ($6.7 million). Depreciation and amortization for
     rental equipment is calculated using an estimated useful life of 15 years
     with a 20% salvage value for rental equipment and an estimated useful life
     of seven years for non-compression equipment, while goodwill is amortized
     over 40 years.

(26) Reflects the net rental payments associated with the proposed new operating
     lease facilities ($40.0 million) and amortization ($2.1 million) of the
     lease structuring and arrangement fees, estimated to be approximately $15.0
     million on the closing of the facilities. Also reflects the elimination of
     the existing operating lease facilities ($20.0 million), including the
     related commitment fee, with assumed aggregate funding under the new
     facilities of $478.4 million by the end of the period, which facilities are
     currently being negotiated. The proposed operating lease facilities will
     replace Universal's and WGC's existing facilities. The rental payments
     under the lease facilities are assumed to include an amount based on LIBOR
     plus a variable amount depending on UCI's operating and financial results,
     applied to the funded amount of the leases. The operating lease
     calculations assume an interest rate of 8.86% and a seven-year lease term.
     A fluctuation of .125% of actual rates related to the proposed new
     operating lease facilities would result in an approximate change of
     $507,000 in rental payments on an annual basis.

(27) Reflects the adjustment of interest expense ($5.3 million) related to the
     retirement of WGC's indebtedness at the beginning of the period. Also
     includes the net adjustment for the amortization of up-front financing
     costs and commitment fees associated with the proposed revolving credit
     facility ($0.1 million).

(28) Represents interest income generated on an average excess cash balance of
     $128.5 million invested at a rate equivalent to Universal's proposed new
     senior secured notes operating lease facility. The effect of a .25% change
     in interest rates on income (loss) before extraordinary items would be $0.2
     million.

(29) Includes the effect of the 7,275,000 shares offered in, and the outstanding
     stock split and conversion that occurred concurrently with, UCH's initial
     public offering and the 13,750,000 shares of UCH's common stock to be
     issued to an affiliate of Weatherford in the WGC acquisition as if these
     transactions had occurred at April 1, 1999. Excludes options to purchase up
     to 318,000 shares of UCH's common stock that we are obligated to issue to
     certain WGC employees in connection with the WGC acquisition.
